Currently you can ask the target symbols add command to locate the debug
symbols for the current frame. This patch add an options to do that for
the whole call stack.

This moves the logic for adding symbols based on UUID, file and frame

Modify OpenOptions enum to open the future path into synchronizing
vFile:open bits with GDB. Currently, LLDB and GDB use different flag
models effectively making it impossible to match bits. Notably, LLDB
uses two bits to indicate read and write status, and uses union of both
for read/write. GDB uses a value of 0 for read-only, 1 for write-only
and 2 for read/write.
In order to future-proof the code for the GDB variant:
1. Add a distinct eOpenOptionReadWrite constant to be used instead
of (eOpenOptionRead | eOpenOptionWrite) when R/W access is required.
2. Rename eOpenOptionRead and eOpenOptionWrite to eOpenOptionReadOnly
and eOpenOptionWriteOnly respectively, to make it clear that they
do not mean to be combined and require update to all call sites.
3. Use the intersection of all three flags when matching against
the three possible values.
This commit does not change the actual bits used by LLDB.

Mostly by converting uses of GetErrorStream to AppendError,
so that the call to SetStatus is implicit.
Some remain where it isn't certain that you'll have a message
to set, or you want the output to be on stdout.
One place in CommandObjectWatchpoint previously didn't set
the status to failed at all. However it's pretty obvious
that it should do so.

A long time ago LLDB wanted to start using StringRef instead of
C-Strings/ConstString but was blocked by the fact that the StringRef constructor
that takes a C-string was asserting that the C-string isn't a nullptr. To
workaround this, D24697 introduced a special function called `withNullAsEmpty`
and that's what LLDB (and only LLDB) started to use to build StringRefs from
C-strings.
A bit later it seems that `withNullAsEmpty` was declared too awkward to use and
instead the assert in the StringRef constructor got removed (see D24904). The
rest of LLDB was then converted to StringRef by just calling the now perfectly
usable implicit constructor.
However, all the calls to `withNullAsEmpty` just remained and are now just
strange artefacts in the code base that just look out of place. It's also
curiously a LLDB-exclusive function and no other project ever called it since
it's introduction half a decade ago.
This patch removes all uses of `withNullAsEmpty`. The follow up will be to
remove the function from StringRef.

TargetList::CreateTarget automatically adds created target to the list, however,
CommandObjectTargetCreate does some additional preparation after creating a target
and which can fail. The command should remove created target if it failed. Since
the function has many ways to return, scope guard does this work safely.
Changes to the TargetList make target adding and selection more transparent.
Other changes remove unnecessary SetSelectedTarget after CreateTarget.

Currently, `target create` has no --platform option. However,
TargetList::CreateTargetInternal which is called under the hood, will
return an error when either no platform or multiple matching platforms
are found, saying that a platform should be specified with --platform.
This patch adds the platform option, but that doesn't solve either of
these errors.
- If more than one platform matches, specifying the platform isn't
going to fix that. The current code will only look at the
architecture instead. I've updated the error message to ask the user
to specify an architecture.
- If no architecture is found, specifying a new one via platform isn't
going to change that either because we already try to find one that
matches the given architecture.

This patch has no effect for C and C++. In more dynamic languages,
such as Objective-C and Swift GetByteSize() needs to call into the
language runtime, so it's important to pass one in where possible. My
primary motivation for this is some work I'm doing on the Swift
branch, however, it looks like we are also seeing warnings in
Objective-C that this may resolve. Everything in the SymbolFile
hierarchy still passes in nullptrs, because we don't have an execution
context in SymbolFile, since SymbolFile transcends processes.

values in CommandObjects
Summary:
This replaces the current use of LLDB's own `StringConvert` with LLVM's
`to_integer` which has a less error-prone API and doesn't use special 'error
values' to designate parsing problems.
Where needed I also added missing error handling code that prints a parsing
error instead of continuing with the error value returned from `StringConvert`
(which either gave a cryptic error message or just took the error value
performed an incorrect action with it. For example, `frame recognizer delete -1`
just deleted the frame recognizer at index 0).

When trying to read a core file that is not owned by the user running lldb
and that doesn't have read permission on the file, lldb shows a misleading
error message:
```
Unable to find process plug-in for core file
```
This is due to the fact that currently, lldb doesn't check the file
ownership. And when trying to to open and read a core file, the syscall
fails, which prevents a process to be created.
Since lldb already have a portable `open` syscall interface, lets take
advantage of that and delegate the error handling to the syscall
itself. This way, no matter if the file exists or if the user has proper
ownership, lldb will always try to open the file, and behave accordingly
to the error code returned.

Summary:
The interactions between the environment settings (`target.env-vars`,
`target.inherit-env`) and the inferior life-cycle are non-obvious
today. For example, if `target.inherit-env` is set, the `target.env-vars`
setting will be augmented with the contents of the host environment
the first time the launch environment is queried (usually at
launch). After that point, toggling `target.inherit-env` will have no
effect as there's no tracking of what comes from the host and what is
a user setting.
This patch computes the environment every time it is queried rather
than updating the contents of the `target.env-vars` property. This
means that toggling the `target.inherit-env` property later will now
have the intended effect.
This patch also adds a `target.unset-env-vars` settings that one can
use to remove variables from the launch environment. Using this, you
can inherit all but a few of the host environment.
The way the launch environment is constructed is:
1/ if `target.inherit-env` is set, then read the host environment
into the launch environment.
2/ Remove for the environment the variables listed in
`target.unset-env`.
3/ Augment the launch environment with the contents of
`target.env-vars`. This overrides any common values with the host
environment.
The one functional difference here that could be seen as a regression
is that `target.env-vars` will not contain the inferior environment
after launch. The patch implements a better alternative in the
`target show-launch-environment` command which will return the
environment computed through the above rules.

pointers
Summary:
All of our lookup APIs either use `CompilerDeclContext &` or `CompilerDeclContext *` semi-randomly it seems.
This leads to us constantly converting between those two types (and doing nullptr checks when going from
pointer to reference). It also leads to the confusing situation where we have two possible ways to express
that we don't have a CompilerDeclContex: either a nullptr or an invalid CompilerDeclContext (aka a default
constructed CompilerDeclContext).
This moves all APIs to use references and gets rid of all the nullptr checks and conversions.

* [NFC] Renamed local `matching_module_list` to `matching_modules` for
conciseness.
* [NFC] Eliminated redundant local variable `num_matches` to reduce the risk
that changes get it out of sync with `matching_modules.GetSize()`.
* Used an early return from case where the symbol file specified matches
multiple modules. This is a slight behavior change, but it's an improvement:
It didn't make sense to tell the user that the symbol file simultaneously
matched multiple modules and no modules.
* [NFC] Used an early return from the case where no matches are found, to
better align with LLVM coding style.
* [NFC] Simplified call of `AppendWarningWithFormat("%s", stuff)` to
`AppendWarning(stuff)`. I don't think this adds any copies. It does
construct a StringRef, but it was going to have to scan the string for the
length anyway.
* [NFC] Removed unnecessary comments and reworded others for clarity.
* Used an early return if the symbol file could not be loaded. This is a
behavior change because previously it could fail silently.
* Used an early return if the object file could not be retrieved from the
symbol file. Again, this is a change because now there's an error message.
* [NFC] Eliminated a namespace alias that wasn't particularly helpful.

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of

This doesn't actually modify StringRef yet, I'll do that in a follow-up.

Summary:
A *.cpp file header in LLDB (and in LLDB) should like this:
```
//===-- TestUtilities.cpp -------------------------------------------------===//
```
However in LLDB most of our source files have arbitrary changes to this format and
these changes are spreading through LLDB as folks usually just use the existing
source files as templates for their new files (most notably the unnecessary
editor language indicator `-*- C++ -*-` is spreading and in every review
someone is pointing out that this is wrong, resulting in people pointing out that this
is done in the same way in other files).
This patch removes most of these inconsistencies including the editor language indicators,
all the different missing/additional '-' characters, files that center the file name, missing
trailing `===//` (mostly caused by clang-format breaking the line).

Summary:
CompileUnit is a complicated class. Having it be implicitly convertible
to a FileSpec makes reasoning about it even harder.
This patch replaces the inheritance by a simple member and an accessor
function. This avoid the need for casting in places where one needed to
force a CompileUnit to be treated as a FileSpec, and does not add much
verbosity elsewhere.
It also fixes a bug where we were wrongly comparing CompileUnit& and a
CompileUnit*, which compiled due to a combination of this inheritance
and the FileSpec*->FileSpec implicit constructor.
