Some distributions of python have their version defined as follows in patchlevel.h (note the '+'):
#define PY_VERSION "2.7.9+"
The '+' char needs to be stripped by the cmake regex so that LLDBs python lib detection is successful.

Newer versions of CMake include a "smarter" FindLibxml2 package.
In theory this is a good thing, but on Windows it's now smart
enough to find the version that comes with Gnuwin32, which doesn't
appear to be a valid libxml2 distribution. Or at the very least,
LLDB currently uses some header files from libxml2 that are not
part of this distribution.
Nobody on Windows is using any of this functionality right now
anyway, so just disable it.

Adding the following flag to a cmake line:
-DLLDB_EXPORT_ALL_SYMBOLS=TRUE
will cause all symbols to be exported from liblldb. This enables the llvm
backtrace mechanism to see and report backtrace symbols properly when using
(lldb) log enable --stack ...
Prior to this change, only the SB API symbols would show up on Linux and other
systems that use a public-symbols-based backtrace lookup mechanism.
log enable --stack ... is a very handy, quick way to understand the flow
of how some log lines are getting hit within lldb without having to hook
up a top-level debugger over your current debug session.

Summary:
This is Darwin only.
The symbol defined by ${LLDB_VERS_GENERATED_FILE} is used by
source/lldb.cpp, so anything that uses lldb.cpp (which is in
lldbBase) should also have the generated symbol. This means
that the entire process can be centralized within source/CMakeLists.txt
where lldbBase is constructed.
Additionally, the custom command should have dependencies on the
project file as well as the generation script so that if either
changes, the version file is correctly re-generated and everything
is re-linked appropriately.
* cmake/LLDBDependencies.cmake: Remove everything related to
the generated version file from here.
* source/CMakeLists.txt: On Darwin, add the generated version
file to the sources that make up lldbBase. Also, create a
custom target and make lldbBase depend on it to re-generate
the generated file as needed.
* source/API/CMakeLists.txt: Don't need to build the generated
version file here or use it to control linking against swig_wrapper.
* tools/lldb-server/CMakeLists.txt: Likewise.

Summary:
Previously `CMAKE_BUILD_TYPE` was used to determine whether to link in `python27.lib` or `python27_d.lib`, unfortunately this only works reliably when using a CMake generator that generates a single build configuration (e.g. Ninja). The Visual Studio CMake generator generates four build configurations at once (`Debug`, `Release`, `RelWithDebInfo`, `MinSizeRel`), so if `CMAKE_BUILD_TYPE` is set to `Debug` all four build configurations end up linking in `python27_d.lib`, this is clearly undesirable.
To ensure that the correct Python lib is used for each build configuration the value of `PYTHON_LIBRARY` is now determined using generator expressions that evaluate to either the debug or release Python lib. The values of `PYTHON_EXECUTABLE` and `PYTHON_DLL` are now likewise determined using generator expressions.
Note that these changes only apply to the Windows build.

Ncurses related symbols can either all be found in libnurses or split
between libncurses and libtinfo. The main LLVM cmake scripts look for the
setupterm symbol and stores the library that has it in TERMINFO_LIBS. This
covers the split and unified ncurses case. LLDB uses symbols that can end
up in libtinfo so this library should be pulled in if it is found.
There is still an exotic case left where LLDB is configured with
-DLLDB_DISABLE_CURSES=NO and LLVM with -DLLVM_ENABLE_TERMINFO=NO but
misconfigurations will always be possible. Possibly a diagnostic could be
added for that.
This fixes bug 24693.

Historically, data formatters all exist in a global repository (the category map)
On top of that, some formatters can be "hardcoded" when the conditions under which they apply are not expressible as a typename (or typename regex)
This change paves the way to move formatters into per-language buckets such that the C++ plugin is responsible for ownership of the C++ formatters, and so on
The advantages of this are:
a) language formatters only get created when they might apply
b) formatters for a language are clearly owned by the matching language plugin
The current model is one of static instantiation, that is a language knows the full set of formatters it vends and that is only asked-for once, and then handed off to the FormatManager
In a future revision it might be interesting to add similar ability to the language runtimes, and monitor for certain shared library events to add even more library-specific formatters
No formatters are moved as part of this change, so practically speaking this is NFC

This patch deprecates the three Python CMake variables in favor of
a single variable PYTHON_HOME which points to the root of a python
installation. Since building Python doesn't output the files in
a structure that is compatible with the PYTHONHOME environment
variable, we also provide a script install_custom_python.py which
will copy the output of a custom python build to the correct
directory structure.
The supported workflow after this patch will be to build python
once for each configuration and architecture {Debug,Release} x {x86,x64}
and then run the script. Then run CMake specifying -DPYTHON_HOME=<path>
The first time you do this will probably require you to delete your
CMake cache.
The old workflow is still supported during a transitionary period,
but a warning is printed at CMake time, and this will eventually
be removed.

This creates a new top-level folder called Initialization which
is intended to hold code specific to LLDB system initialization.
Currently this holds the Initialize() and Terminate() functions,
as well as the fatal error handler.
This provides a means to break the massive dependency cycle which
is caused by the fact that Debugger depends on Initialize and
Terminate which then depends on the entire LLDB project. With
this structure, it will be possible for applications to invoke
lldb_private::Initialize() directly, and have that invoke

Sigh. There's really not a good alternative until we decouple
python from lldb better. The only way the build works right now
is by having every executable link against every LLDB library.
This causes implicit transitive link dependencies on the union
of everything that LLDB brings in. Which means that if all we
want is one header file from interpreter, we have to bring in
everything, including everything that everything depends on,
which means python.
There's outstanding efforts to address this, but it's not yet
complete. So until then, this is all we can do.

The existing state of affairs was getting a little unwieldy.

An OBJECT library is a special type of CMake library that produces
no archive, has no link interface, and no link inputs. It is like
a regular archive, just without the physical output. To link
against an OBJECT library, you reference it in the *source* file
list of a library using the special syntax $<TARGET_OBJECTS:lldbAPI>.
This will cause every object file to be passed to the linker
independently, as opposed to a single archive being passed to the
linker.
This is *extremely* important on Windows. lldbAPI exports all of the
SB classes using __declspec(dllexport). Unfortunately for technical
reasons it is not possible (well, extremely difficult) to get the
linker to propagate a __declspec(dllexport) attribute from a symbol
in an object file in an archive to a DLL that links against that
archive. The solution to this is for the DLL to link the object files
directly. So lldbAPI must be an OBJECT library.
This fixes an issue that has been present since the duplicated
lldbAPI file lists were removed, which would cause linker failures.
As a side effect, this also makes LLDB_DISABLE_PYTHON=1 work again
on Windows, which was previously totally broken.
