Currently, the interpreter's context is not updated until a command is executed.
This has resulted in the behavior of SB-interface functions and some commands
depends on previous user actions. The interpreter's context can stay uninitialized,
point to a currently selected target, or point to one of previously selected targets.
This patch removes any usages of CommandInterpreter::UpdateExecutionContext.
CommandInterpreter::HandleCommand* functions still may override context temporarily,
but now they always restore it before exiting. CommandInterpreter saves overriden
contexts to the stack, that makes nesting commands possible.
Added test reproduces one of the issues. Without this fix, the last assertion fails
because interpreter's execution context is empty until running "target list", so,
the value of the global property was updated instead of process's local instance.

The intention is not to allow stop-hook commands to query the
user, so this is correct. It also works around a deadlock in
switching to the Python Session to execute python based commands
in the stop hook when the Debugger stdin is backed by a FILE *.

Make it possible to use a relative path in command script import to the
location of the file being sourced. This allows the user to put Python
scripts next to LLDB command files and importing them without having to
specify an absolute path.
To enable this behavior pass `-c` to `command script import`. The
argument can only be used when sourcing the command from a file.

This is the first in a series of patches that will adds a new processor trace plug-in to LLDB.
The idea for this first patch to to add the plug-in interface with simple commands for the trace files that can "load" and "dump" the trace information. We can test the functionality and ensure people are happy with the way things are done and how things are organized before moving on to adding more functionality.
Processor trace information can be view in a few different ways:
- post mortem where a trace is saved off that can be viewed later in the debugger
- gathered while a process is running and allow the user to step back in time (with no variables, memory or registers) to see how each thread arrived at where it is currently stopped.
This patch attempts to start with the first solution of loading a trace file after the fact. The idea is that we will use a JSON file to load the trace information. JSON allows us to specify information about the trace like:
- plug-in name in LLDB
- path to trace file
- shared library load information so we can re-create a target and symbolicate the information in the trace
- any other info that the trace plug-in will need to be able to successfully parse the trace information
- cpu type
- version info
- ???
A new "trace" command was added at the top level of the LLDB commmands:
- "trace load"
- "trace dump"
I did this because if we load trace information we don't need to have a process and we might end up creating a new target for the trace information that will become active. If anyone has any input on where this would be better suited, please let me know. Walter Erquinigo will end up filling in the Intel PT specific plug-in so that it works and is tested once we can agree that the direction of this patch is the correct one, so please feel free to chime in with ideas on comments!

Previously, before loading the REPL language-specific init file, lldb
checked the selected target language in which case it returned an unknown
language type with the REPL target.
Instead, the patch calls `Language::GetLanguagesSupportingREPLs` and
look for the first element of that set. In case lldb was not configured
with a REPL language, then, it will just stop sourcing the REPL init
file and fallback to the original logic (continuing with the default
init file).

This patch changes the command interpreter sourcing logic for the REPL
init file. Instead of looking for a arbitrary file name, it standardizes
the REPL init file name to match to following scheme:
`.lldbinit-<language>-repl`

This patch adds the infrastructure to have language specific REPL init
files. It's the foundation work to a following patch that will introduce
Swift REPL init file.
When lldb is launched with the `--repl` option, it will look for a REPL
init file in the home directory and source it. This overrides the
default `~/.lldbinit`, which content might make the REPL behave
unexpectedly. If the REPL init file doesn't exists, lldb will fall back
to the default init file.

This is relanding D81001. The patch originally failed as on newer editline
versions it seems CC_REFRESH will move the cursor to the start of the line via
\r and then back to the original position. On older editline versions like
the one used by default on macOS, CC_REFRESH doesn't move the cursor at all.
As the patch changed the way we handle tab completion (previously we did
REDISPLAY but now we're doing CC_REFRESH), this caused a few completion tests
to receive this unexpected cursor movement in the output stream.
This patch updates those tests to also accept output that contains the specific
cursor movement commands (\r and then \x1b[XC). lldbpexpect.py received an
utility method for generating the cursor movement escape sequence.
Original summary:
I implemented autosuggestion if there is one possible suggestion.
I set the keybinds for every character. When a character is typed, Editline::TypedCharacter is called.
Then, autosuggestion part is displayed in gray, and you can actually input by typing C-k.
Editline::Autosuggest is a function for finding completion, and it is like Editline::TabCommand now, but I will add more features to it.
Testing does not work well in my environment, so I can't confirm that it goes well, sorry. I am dealing with it now.

This patch moves the `history` subcommand from the `command` to `session`
command. I think it makes more sense to have it there because as the `command`
usage suggests, it should be used to manage custom LLDB commands.
However, `history` is essentially tied to a debugging session and holds
all the commands (not specifically custom ones).
This also makes it more discoverable by adding an alias for it (mimicking
the shell builtin).

This patch introduce a new feature that allows the users to save their
debugging session's transcript (commands + outputs) to a file.
It differs from the reproducers since it doesn't require to capture a
session preemptively and replay the reproducer file in lldb.
The user can choose the save its session manually using the session save
command or automatically by setting the interpreter.save-session-on-quit
on their init file.
To do so, the patch adds a Stream object to the CommandInterpreter that
will hold the input command from the IOHandler and the CommandReturnObject
output and error. This way, that stream object accumulates passively all
the interactions throughout the session and will save them to disk on demand.
The user can specify a file path where the session's transcript will be
saved. However, it is optional, and when it is not provided, lldb will
create a temporary file name according to the session date and time.

This patch introduces the `(-h|--host)` option to the `platform shell`
command. It allows the user to run shell commands from the host platform
(always available) without putting lldb in the background.
Since the default behaviour of `platform shell` is to run the command of
the selected platform, having such a choice can be quite handy when
debugging remote targets, for instances.
This patch also introduces a `shell` alias, to improve the command
discoverability and make it more convenient to use for the user.

This is mostly mechanical from a custom clang-tidy check, with a lot of

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:
This patch removes File::SetStream() and File::SetDescriptor(),
and replaces most direct uses of File with pointers to File.
Instead of calling SetStream() on a file, we make a new file and
replace it.
My ultimate goal here is to introduce a new API class SBFile, which
has full support for python io.IOStream file objects. These can
redirect read() and write() to python code, so lldb::Files will
need a way to dispatch those methods. Additionally it will need some
form of sharing and assigning files, as a SBFile will be passed in and
assigned to the main IO streams of the debugger.
In my prototype patch queue, I make File itself copyable and add a
secondary class FileOps to manage the sharing and dispatch. In that
case SBFile was a unique_ptr<File>.
(here: https://github.com/smoofra/llvm-project/tree/files)
However in review, Pavel Labath suggested that it be shared_ptr instead.
(here: https://reviews.llvm.org/D67793)
In order for SBFile to use shared_ptr<File>, everything else should
as well.
If this patch is accepted, I will make SBFile use a shared_ptr
I will remove FileOps from future patches and use subclasses of File
instead.

This is beneficial on its own, as llvm::Expected is a more modern

We currently have two lists in the CompletionRequest that we
inherited from the old API: The complete list of arguments ignoring
where the user requested completion and the list of arguments that
stops at the cursor. Having two lists of arguments is confusing
and can lead to subtle errors, so let's remove the complete list
until we actually need it.

The fact that index==-1 means "no arguments" is not obvious and only

Not fully NFC as we now also correctly update the partial argument list
when injecting the fake empty argument in the CompletionRequest
constructor.
