Pavel Labath 9d5e37ed8c [lldb] (Semi-automatically) format .swig files
I've found my recent ventures into the swig land painful because
of the strange way they are formatted. This patch attempts to alleviate
future headaches by formatting these files into something resembling the
normal llvm style.

Unfortunately, completely formatting these files automatically does not
work because clang format gets confused by swigs % syntax, so I have
employed a hybrid approach where I formatted blocks of c++ code with
clang-format and then manually massaged the code until it looked
reasonable (and compiled).

I don't expect these files to remain perfectly formatted (although, if
one's editor is configured to configure the current line/block on
request, one can get pretty good results by using it judiciously), but
at least it will prevent the (mangled form of the) old lldb style being
proliferated endlessly.

Pavel Labath 82de8df26f [lldb] Clarify StructuredDataImpl ownership
StructuredDataImpl ownership semantics is unclear at best. Various
structures were holding a non-owning pointer to it, with a comment that
the object is owned somewhere else. From what I was able to gather that
"somewhere else" was the SBStructuredData object, but I am not sure that
all created object eventually made its way there. (It wouldn't matter
even if they did, as we are leaking most of our SBStructuredData
objects.)

Since StructuredDataImpl is just a collection of two (shared) pointers,
there's really no point in elaborate lifetime management, so this patch
replaces all StructuredDataImpl pointers with actual objects or
unique_ptrs to it. This makes it much easier to resolve SBStructuredData
leaks in a follow-up patch.

Pedro Tammela 532e4203c5 [lldb/Lua] add support for Lua function breakpoint
Adds support for running a Lua function when a breakpoint is hit.

Example:
   breakpoint command add -s lua -F abc

The above runs the Lua function 'abc' passing 2 arguments. 'frame', 'bp_loc' and 'extra_args'.

A third parameter 'extra_args' is only present when there is structured data
declared in the command line.

Example:
   breakpoint command add -s lua -F abc -k foo -v bar

Pedro Tammela 5997e8987f [lldb/Lua] add initial Lua typemaps
This patch adds the integer handling typemaps and the typemap for
string returning functions.

The integer handling typemaps overrides SWIG's own typemaps to distinct
the handling of integers from floating point.

The typemap for string returning functions is a port of Python's
typemap.

Pedro Tammela a0d7406ae8 [LLDB/Lua] add support for one-liner breakpoint callback
These callbacks are set using the following:
   breakpoint command add -s lua -o "print('hello world!')"

The user supplied script is executed as:
   function (frame, bp_loc, ...)
      <body>
   end

So the local variables 'frame', 'bp_loc' and vararg are all accessible.
Any global variables declared will persist in the Lua interpreter.
A user should never hold 'frame' and 'bp_loc' in a global variable as
these userdatas are context dependent.

Jonas Devlieghere fbfd831dda [lldb] Fix relative imports and set the appropriate include dirs
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.

Jonas Devlieghere c135744b1d [lldb/CMake] Separate CMake code for Lua and Python (NFC)
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.
