This removes references to PT_XXX macros from the file, as they were not used anyway. It also
changes the macro used to check for the definition of __ptrace_request, as there are other C

trade-offs. When LLDB's multi-line editing support was first introduced
for expressions / REPL contexts the behavior was as follows:
* The Return key is treated as a line-break except at the end of the input
buffer, where a completeness test is applied
This worked well enough when writing code, and makes it trivial to insert
new lines above code you've already typed. Just use cursor navigation to
move up and type freely. Where it was awkward is that the gesture to insert
a line break and end editing is conflated for most people. Sometimes you
want Return to end the editing session and other times you want to insert
a line break.
This commit changes the behavior as follows:
* The Return key is treated as the end of editing except at the end of the
input buffer, where a completeness test is applied
* The Meta+Return sequence is always treated as a line break. This is
consistent with conventions in Facebook and elsewhere since
Alt/Option+Return is often mapped to Meta+Return. The unfortunate
exception is on macOS where this *can* be the case, but isn't by
default. Sigh.
Note that by design both before and after the patch pasting a Return
character always introduces a line break.

Summary:
In the case of client sockets, we are not binding to a specific port, so we
should be able to just request a new one. Disregarding refactors, this code
has been here since the initial LLDB checkin, so I was unable to figure out
whether it was added as a fix for a specific problem, or just for symmetry
with server sockets, but I see no side-effect from removing it now. I was
still able to create 10000 connections within a couple of seconds, so I think
it's unlikely we will exhaust the port space (previously, I would get an
error after a couple thousand connections).
This fixes an occasional issue with connecting to the android debug bridge
deamon on OSX when running the test suite, which would occasionaly fail with
EADDRINUSE. My best guess is that this was happening because two processes
were assigned the same client port number, and then things blew up because
they were both trying to connect to the same ADB server port. I have not
observed this issue happening on Linux or Windows.

When USE_SETUPTERM_WORKAROUND is enabled, we were calling setupterm() multiple times and leaking memory on each subsequent call. This is now fixed by calling setupterm() once in the constructor and tracking if we have already setup a terminal for a file descriptor.
Calls to "el_set (m_editline, EL_ADDFN, ..." were leaking memory. If we switch over to call el_wset with wide strings when LLDB_EDITLINE_USE_WCHAR is set, then we no longer leak memory each time we construct a new Editline object.
The calls to "el_set (m_editline, EL_ADDFN, ..." were changed over to call "el_wset (m_editline, EL_ADDFN, ...". Note that when LLDB_EDITLINE_USE_WCHAR is not defined, then el_wset is #define'ed to el_set. All strings are wrapped in EditLineConstString which will use wide strings when needed, and normal C strings when LLDB_EDITLINE_USE_WCHAR is not defined.

This is a pretty straightforward first pass over removing a number of uses of
Mutex in favor of std::mutex or std::recursive_mutex. The problem is that there
are interfaces which take Mutex::Locker & to lock internal locks. This patch
cleans up most of the easy cases. The only non-trivial change is in
CommandObjectTarget.cpp where a Mutex::Locker was split into two.

The main issues were:
- Listeners recently were converted over to used by getting a shared pointer to a listener. And when they listened to broadcasters they would get a strong reference added to them meaning the listeners would never go away. This caused memory usage to increase and would cause performance issue if many steps were done.
- The lldb_private::Process private state thread had an issue where if a "stop" contol signal was attempted to be sent to that thread, it could end up not responding in 2 seconds and end up getting cancelled which might cause us to cancel a thread that had a mutex locked and it would deadlock the test.
This change makes broadcasters hold onto weak references to listeners. It also fixes some bad threading code that had races inside of it by making the m_events_mutex be non-recursive and getting rid of fragile use of a Predicate<bool> to say that new events are available, and replacing it with using the m_events_mutex with a new m_events_condition to control access to the events in a safer way.
The private state thread now uses a safer way to communicate that the control event has been received by the private state thread: it makes a EventDataReceipt instance that it attaches to the event that sends the control to the private state thread and used this to synchronize the fact that the private state thread has received the event instead of using a Predicate<bool> to convey the info. When the signal event is received, it will pull the event off of the queue in the private state thread and cause the EventData::DoOnRemoval() to be called, which will signal that the event has been received. This cleans up the signal delivery notification so it doesn't rely on a member variable of the process class to convey the info.
std::shared_ptr<EventDataReceipt> event_receipt_sp(new EventDataReceipt());
m_private_state_control_broadcaster.BroadcastEvent(signal, event_receipt_sp);

Summary:
This replaces the C-style "void *" baton of the child process monitoring functions with a more
C++-like API taking a std::function. The motivation for this was that it was very difficult to
handle the ownership of the object passed into the callback function -- each caller ended up
implementing his own way of doing it, some doing it better than others. With the new API, one can
just pass a smart pointer into the callback and all of the lifetime management will be handled
automatically.
This has enabled me to simplify the rather complicated handshake in Host::RunShellCommand. I have
left handling of MonitorDebugServerProcess (my original motivation for this change) to a separate
commit to reduce the scope of this change.

Summary:
AdbClient was attempting to handle the case where the socket input arrived in pieces, but it was
failing to handle the case where the connection was closed before that happened. In this case, it
would just spin in an infinite loop calling Connection::Read. (This was also the cause of the
spurious timeouts on the darwin->android buildbot. The exact cause of the premature EOF remains
to be investigated, but is likely a server bug.)
Since this wait-for-a-certain-number-of-bytes seems like a useful functionality to have, I am
moving it (with the infinite loop fixed) to the Connection class, and adding an
appropriate test for it.

environment and that might not always be set. Our FileSpec class uses this function to resolve any paths that start with "~/" on systems that support home directories as '~'. I have modified FileSpec::ResolveUsername (llvm::SmallVectorImpl<char> &path) to deal with the cases where llvm::sys::path::home_directory() returns false by digging a little further on unix systems and setting "HOME" in the environment so that subsequent calls to llvm::sys::path::home_directory() will succeed.

This patch adds support for Linux on SystemZ:
- A new ArchSpec value of eCore_s390x_generic
- A new directory Plugins/ABI/SysV-s390x providing an ABI implementation
- Register context support
- Native Linux support including watchpoint support
- ELF core file support
- Misc. support throughout the code base (e.g. breakpoint opcodes)
- Test case updates to support the platform
This should provide complete support for debugging the SystemZ platform.
Not yet supported are optional features like transaction support (zEC12)
or SIMD vector support (z13).
There is no instruction emulation, since our ABI requires that all code
provide correct DWARF CFI at all PC locations in .eh_frame to support
unwinding (i.e. -fasynchronous-unwind-tables is on by default).
The implementation follows existing platforms in a mostly straightforward
manner. A couple of things that are different:
- We do not use PTRACE_PEEKUSER / PTRACE_POKEUSER to access single registers,
since some registers (access register) reside at offsets in the user area
that are multiples of 4, but the PTRACE_PEEKUSER interface only allows
accessing aligned 8-byte blocks in the user area. Instead, we use a s390
specific ptrace interface PTRACE_PEEKUSR_AREA / PTRACE_POKEUSR_AREA that
allows accessing a whole block of the user area in one go, so in effect
allowing to treat parts of the user area as register sets.
- SystemZ hardware does not provide any means to implement read watchpoints,
only write watchpoints. In fact, we can only support a *single* write
watchpoint (but this can span a range of arbitrary size). In LLDB this
means we support only a single watchpoint. I've set all test cases that
require read watchpoints (or multiple watchpoints) to expected failure
on the platform. [ Note that there were two test cases that install
a read/write watchpoint even though they nowhere rely on the "read"
property. I've changed those to simply use plain write watchpoints. ]

Summary:
In D18689, I removed the call to Normalize() in FileSpec::SetFile, because it no longer seemed
needed, and it resolved a quirk in the FileSpec API (spec.GetCString() returnes a path with
backslashes, but spec.GetDirectory().GetCString() has forward slashes). This turned out to be a
problem because we would consider paths with different separators as different (which led to
unresolved breakpoints for instance).
Here, I am putting back in the call to Normalize() and adding a unittest for FileSpec::Equal. I
am commenting out the GetDirectory unittests until we figure out the what is the expected
behaviour here.

Summary:
Even though FileSpec attempted to handle both kinds of path syntaxes (posix and windows) on both
platforms, it relied on the llvm path library to do its work, whose behavior differed on
different platforms. This led to subtle differences in FileSpec behavior between platforms. This
replaces the pieces of the llvm library with our own implementations. The functions are simply
copied from llvm, with #ifdefs replaced by runtime checks for ePathSyntaxWindows.

We want to do a better job presenting errors that occur when evaluating
expressions. Key to this effort is getting away from a model where all
errors are spat out onto a stream where the client has to take or leave
all of them.
To this end, this patch adds a new class, DiagnosticManager, which
contains errors produced by the compiler or by LLDB as an expression
is created. The DiagnosticManager can dump itself to a log as well as
to a string. Clients will (in the future) be able to filter out the
errors they're interested in by ID or present subsets of these errors
to the user.
This patch is not intended to change the *users* of errors - only to
thread DiagnosticManagers to all the places where streams are used. I
also attempt to standardize our use of errors a bit, removing trailing
newlines and making clients omit 'error:', 'warning:' etc. and instead
pass the Severity flag.
The patch is testsuite-neutral, with modifications to one part of the
MI tests because it relied on "error: error:" being erroneously
printed. This patch fixes the MI variable handling and the testcase.

IOHandler's files instead of always using stdin/out/err.
Removed lldb_private::File::Duplicate() and the copy constructor and the assignment operator that used to duplicate the file handles and made them private so no one uses them. Previously the lldb_private::File::Duplicate() function duplicated files that used file descriptors, (int) but not file streams (FILE *), so the lldb_private::File::Duplicate() function only worked some of the time. No one else excep thee ScriptInterpreterPython was using these functions, so that aren't needed nor desired. Previously every time you would drop into the python interpreter we would duplicate files, and now we avoid this file churn.

PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.
Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows. This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.
This patch only adds support for line tables. It does not return
information about functions, types, global variables, or anything
else. This functionality will be added in a followup patch.

Paths on Windows are not case-sensitive. Because of this, if a file
is called main.cpp, you should be able to set a breakpoint on it
by using the name Main.cpp. In an ideal world, you could just
tell people to match the case, but in practice this can be a real
problem as it requires you to know whether the person who compiled
the program ran "clang++ main.cpp" or "clang++ Main.cpp", both of
which would work, regardless of what the file was actually called.

There were a number of problems preventing this from working:
1. The SWIG typemaps for converting Python lists to and from C++
arrays were not updated for Python 3. So they were doing things
like PyString_Check instead of using the PythonString from
PythonDataObjects.
2. ProcessLauncherWindows was ignoring the environment completely.
So any test that involved launching an inferior with any kind
of environment variable would have failed.
3. The test itself was using process.GetSTDOUT(), which isn't
implemented on Windows. So this was changed to save the
value of the environment variable in a local variable and
have the debugger look at the value of the variable.
