This patch introduces a concept of "frame recognizer" and "recognized frame". This should be an extensible mechanism that retrieves information about special frames based on ABI, arguments or other special properties of that frame, even without source code. A few examples where that could be useful could be 1) objc_exception_throw, where we'd like to get the current exception, 2) terminate_with_reason and extracting the current terminate string, 3) recognizing Objective-C frames and automatically extracting the receiver+selector, or perhaps all arguments (based on selector).

This change allows you to write a new breakpoint type where the
logic for setting breakpoints is determined by a Python callback
written using the SB API's.

Summary:
Swig wraps C++ code into SWIG_PYTHON_THREAD_BEGIN_ALLOW; ... SWIG_PYTHON_THREAD_END_ALLOW;
Thus, LLDB crashes with "Fatal Python error: Python memory allocator called without holding the GIL" when calls an lldb_SB***___str__ function.

Summary:
This change fixes one issue with `lldb.command`, and also reduces the implementation.
The fix: a command function's docstring was not shown when running `help <command_name>`. This is because the docstring attached the source function is not propagated to the decorated function (`f.__call__`). By returning the original function, the docstring will be properly displayed by `help`.
Also with this change, the command name is assumed to be the function's name, but can still be explicitly defined as previously.
Additionally, the implementation was updated to:
* Remove inner class
* Remove use of `inspect` module
* Remove `*args` and `**kwargs`

When introduced, breakpoint names were just tags that you could
apply to breakpoints that would allow you to refer to a breakpoint
when you couldn't capture the ID, or to refer to a collection of
breakpoints.
This change makes the names independent holders of breakpoint options
that you can then apply to breakpoints when you add the name to the
breakpoint. It adds the "breakpoint name configure" command to set
up or reconfigure breakpoint names. There is also full support for
then in the SB API, including a new SBBreakpointName class.
The connection between the name and the breakpoints
sharing the name remains live, so if you reconfigure the name, all the
breakpoint options all change as well. This allows a quick way
to share complex breakpoint behavior among a bunch of breakpoints, and
a convenient way to iterate on the set.
You can also create a name from a breakpoint, allowing a quick way
to copy options from one breakpoint to another.
I also added the ability to make hidden and delete/disable protected
names. When applied to a breakpoint, you will only be able to list,
delete or disable that breakpoint if you refer to it explicitly by ID.
This feature will allow GUI's that need to use breakpoints for their
own purposes to keep their breakpoints from getting accidentally
disabled or deleted.

Summary:
The current version of LLDB installs six.py into global python library directory. This approach produces conflicts downstream with distribution's py-six copy.
Introduce new configure option LLDB_USE_SYSTEM_SIX (disabled by default). Once specified as TRUE, six.py won't be installed to Python's directory.
Add new option in finishSwigWrapperClasses.py, namely --useSystemSix.

A combination of broken escaping in CMake and in the python swig
generation scripts meant that the swig generation step would fail
whenever there were spaces or special characters in parameters passed to
swig.
The fix for this in CMakeLists is to use the VERBATIM option on all
COMMAND-based custom builders relying on CMake to properly escape each
argument in the generated file.
Within the python swig scripts, the fix is to call subprocess.Popen with
a list of raw argument strings rather than ones that are incorrectly
manually escaped, then passed to a shell subprocess via
subprocess.Popen(' '.join(params)). This also prevents nasty things
happening such as accidental command-injection.
This allows us to have the swig / python executables in paths containing
special chars and spaces, (or on shared storage on Win32, e.g
\\some\path or C:\Program Files\swig\swig.exe).

Rationale:
scripts/Python/modules: android is excluded at a higher level, so no point in
checking here
tools/lldb-mi: lldb-mi builds fine (with some cosmetic tweaks) on android, and
there is no reason it shouldn't.
tools/lldb-server: LLDB_DISABLE_LIBEDIT/CURSES already take the platform into
account, so there is no point in checking again.
I am reasonably confident this should not break the build on any platform, but
I'll keep an eye out on the bots.

Summary:
If Python is installed to a location that contains spaces
(e.g. "C:\Program Files\Python3") then the build fails while attempting
to run the modify-python-lldb.py script because the path to the Python
executable is not double-quoted before being passed to the shell. The
fix consists of letting Python handle the formatting of the command
line, since subprocess.Popen() is perfectly capable of handling paths
containing spaces if it's given the command and arguments as a list
instead of a single pre-formatted string.

Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.
With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.
The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.
With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

Summary:
Do not assume that liblldb.so is located in $(lldb -P)/../../../lib
when creating the _lldb python symlink. Instead, use the path passed
to LLVM_LIBDIR_SUFFIX, defaulting to $(lldb -P)/../../../lib when this
variable is not set.
