This reverts commit f775fe5964.
I fixed a return type error in the original patch that was causing a test failure.
Also added a REQUIRES: python to the shell test so we'll skip this for
people who build lldb w/o Python.
Also added another test for the error printing.
`struct Py_buffer_RAII` definition uses explicit deleted functions which are not supported by SWIG 2 (only 3).
To get around this I moved this struct to an .h file that is included to avoid being parsed by swig.

LLVM install component targets needs to be in the form of: install-{target}[-stripped]
I tested with:
```
cmake ... -DLLVM_ENABLE_PROJECTS="clang;lldb" -DLLVM_DISTRIBUTION_COMPONENTS="lldb;liblldb;lldb-python-scripts;" ...
DESTDIR=... ninja install-distribution
```
@JDevlieghere `finish_swig_python_scripts` is a really weird name for a distribution component, any reason that it has to be this way?

This patch is a big sed to rename the following variables:
s/PYTHON_LIBRARIES/Python3_LIBRARIES/g
s/PYTHON_INCLUDE_DIRS/Python3_INCLUDE_DIRS/g
s/PYTHON_EXECUTABLE/Python3_EXECUTABLE/g
s/PYTHON_RPATH/Python3_RPATH/g
I've also renamed the CMake module to better express its purpose and for
consistency with FindLuaAndSwig.

After moving python.swig and lua.swig into their respective
subdirectories, the relative paths in these files were out of date. This
fixes that and ensures the appropriate include paths are set in the SWIG
invocation.

Separate the CMake logic for Lua and Python to clearly distinguish
between code specific to either scripting language and the code shared
by both.
What this patch does is:
- Move Python specific code into the bindings/python subdirectory.
- Move the Lua specific code into the bindings/lua subdirectory.
- Add the _python suffix to Python specific functions/targets.
- Fix a dependency issue that would check the binding instead of
whether the scripting language is enabled.
Note that this patch also changes where the bindings are generated,
which might affect downstream projects that check them in.

This was reverted due to a python2-specific bug. Re-landing with a fix
for python2.
Summary:
One small step in my long running quest to improve python exception handling in
LLDB. Replace GetInteger() which just returns an int with As<long long> and
friends, which return Expected types that can track python exceptions

Summary:
The buffer protocol does not allow us to just call PyBuffer_Release
and assume the buffer will still be there. Most things that implement the
buffer protocol will let us get away with that, but not all. We need
to release it at the end of the SWIG wrapper.

Summary:
`SBThread.GetStopDescription` is a curious API as it takes a buffer length as a parameter that specifies
how many bytes the buffer we pass has. Then we fill the buffer until the specified length (or the length
of the stop description string) and return the string length. If the buffer is a nullptr however, we instead
return how many bytes we would have written to the buffer so that the user can allocate a buffer with
the right size and pass that size to a subsequent `SBThread.GetStopDescription` call.
Funnily enough, it is not possible to pass a nullptr via the Python SWIG bindings, so that might be the
first API in LLDB that is not only hard to use correctly but impossible to use correctly. The only way to
call this function via Python is to throw in a large size limit that is hopefully large enough to contain the
stop description (otherwise we only get the truncated stop description).
Currently passing a size limit that is smaller than the returned stop description doesn't cause the
Python bindings to return the stop description but instead the truncated stop description + uninitialized characters
at the end of the string. The reason for this is that we return the result of `snprintf` from the method
which returns the amount of bytes that *would* have been written (which is larger than the buffer).
This causes our Python bindings to return a string that is as large as full stop description but the
buffer that has been filled is only as large as the passed in buffer size.
This patch fixes this issue by just recalculating the string length in our buffer instead of relying on the wrong
return value. We also have to do this in a new type map as the old type map is also used for all methods
with the given argument pair `char *dst, size_t dst_len` (e.g. SBProcess.GetSTDOUT`). These methods have
different semantics for these arguments and don't null-terminate the returned buffer (they instead return the
size in bytes) so we can't change the existing typemap without breaking them.

All the code required to generate the language bindings for Python and
Lua lives under scripts, even though the majority of this code aren't
scripts at all, and surrounded by scripts that are totally unrelated.
I've reorganized these files and moved everything related to the
language bindings into a new top-level directory named bindings. This
makes the corresponding files self contained and much more discoverable.
