We were incorrectly parsing the -C argument to breakpoint set as the
column breakpoint, even though according to the help this should be the
breakpoint command. This fixes that by renaming the option to -u, adding
it to help, and adding a test case.

The 'asynchronously' argument to both GetLLDBCommandsFromIOHandler and
GetPythonCommandsFromIOHandler is true for all call sites. This commit
simplifies the API by dropping it and giving the baton a default
argument.
Currently, there is no option to delete all the watchpoint without LLDB
asking for a confirmation. Besides making the watchpoint delete command
homogeneous with the breakpoint delete command, this option could also
become handy to trigger automated watchpoint deletion i.e. using
breakpoint actions.

The `-r` option for `command script import` is there for legacy
compatibility, however the can_reload flag is always set to true. This
patch removes the flag and any code that relies on it being false.
This ensures that watchpoint command honors the scripting language
passed with `-s`. Currently the argument ignores the actual language and
only uses it to differentiate between lldb and script commands.
- Fix enum entry order.
- Fix missing enum case in CommandObjectBreakpointCommand.
- Add Lua entry to swtich in LanguageToString and simplify the code.

Summary: This removes most of unnecessary includes in the `source/Commands` directory. This was generated by IWYU and a script that fixed all the bogus reports from IWYU. Patch is tested on Linux and macOS.

When running the test suite with always capture on, a handful of tests
are failing because they have multiple targets and therefore multiple
GDB remote connections. The current reproducer infrastructure is capable
of dealing with that.
This patch reworks the GDB remote provider to support multiple GDB
remote connections, similar to how the reproducers support shadowing
multiple command interpreter inputs. The provider now keeps a list of
packet recorders which deal with a single GDB remote connection. During
replay we rely on the order of creation to match the number of packets
to the GDB remote connection.

Summary:
The FileSpec class is often used as a sort of a pattern -- one specifies
a bare file name to search, and we check if in matches the full file
name of an existing module (for example).
These comparisons used FileSpec::Equal, which had some support for it
(via the full=false argument), but it was not a good fit for this job.
For one, it did a symmetric comparison, which makes sense for a function
called "equal", but not for typical searches (when searching for
"/foo/bar.so", we don't want to find a module whose name is just
"bar.so"). This resulted in patterns like:
if (FileSpec::Equal(pattern, file, pattern.GetDirectory()))
which would request a "full" match only if the pattern really contained
a directory. This worked, but the intended behavior was very unobvious.
On top of that, a lot of the code wanted to handle the case of an
"empty" pattern, and treat it as matching everything. This resulted in
conditions like:
if (pattern && !FileSpec::Equal(pattern, file, pattern.GetDirectory())
which are nearly impossible to decipher.
This patch introduces a FileSpec::Match function, which does exactly
what most of FileSpec::Equal callers want, an asymmetric match between a
"pattern" FileSpec and a an actual FileSpec. Empty paterns match
everything, filename-only patterns match only the filename component.
I've tried to update all callers of FileSpec::Equal to use a simpler
interface. Those that hardcoded full=true have been changed to use
operator==. Those passing full=pattern.GetDirectory() have been changed
to use FileSpec::Match.
There was also a handful of places which hardcoded full=false. I've
changed these to use FileSpec::Match too. This is a slight change in
semantics, but it does not look like that was ever intended, and it was
more likely a result of a misunderstanding of the "proper" way to use
FileSpec::Equal.
[In an ideal world a "FileSpec" and a "FileSpec pattern" would be two
different types, but given how widespread FileSpec is, it is unlikely
we'll get there in one go. This at least provides a good starting point
by centralizing all matching behavior.]

Summary:
The IOHandler class source file is currently around 4600 LOC. However only 200
of these lines are concerned with the actual IOHandler class and the rest are the
implementations for Editline, IOHandlerConfirm and the Curses interface. All these
large features also cause that the IOHandler (which is in Core) has a large set of dependencies
on other parts of LLDB.
This patch splits out the code for the curses interface into its own file. This way
the simple IOHandler code is no longer buried in-between much larger functionalities.
Next up is splitting out the other IOHandlers into their own files and then move them
to more appropriate parts of LLDB.

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.

This patch hooks the reproducer infrastructure with the signal handlers.
When lldb crashes with reproducers capture enabled, it will now generate
the reproducer and print a short message the standard out. This doesn't
affect the pretty stack traces, which are still printed before.
This patch also introduces a new reproducer sub-command that
intentionally raises a given signal to test the reproducer signal
handling.
Currently the signal handler is doing too much work. Instead of copying
over files into the reproducers in the signal handler, we should
re-invoke ourselves with a special command line flag that looks at the
VFS mapping and performs the copy.
This is a NO-OP when reproducers are disabled.

Currently nothing prevents you from continuing your debug session after

Summary:
The permissions in a memory region have ternary states (yes, no, don't
know), but the memory region command only prints in binary, treating
"don't know" as "yes", which is particularly confusing as for instance
the unwinder will treat an unknown value as "no".
This patch makes is so that we distinguish all three states when
printing the values, using "?" to indicate the lack of information. It
is implemented via a special argument to the format provider for the
OptionalBool enumeration.

For example, it is pretty easy to write a breakpoint command that implements "stop when my caller is Foo", and
it is pretty easy to write a breakpoint command that implements "stop when my caller is Bar". But there's no
way to write a generic "stop when my caller is..." function, and then specify the caller when you add the
command to a breakpoint.
With this patch, you can pass this data in a SBStructuredData dictionary. That will get stored in
the PythonCommandBaton for the breakpoint, and passed to the implementation function (if it has the right
signature) when the breakpoint is hit. Then in lldb, you can say:
(lldb) break com add -F caller_is -k caller_name -v Foo
More generally this will allow us to write reusable Python breakpoint commands.
