In an effort to reduce binary size for components not wishing to
link against all of LLDB, as well as a parallel effort to reduce
link dependencies on Python, this patch splits out the notion of
LLDB initialization into "full" and "common" initialization.
All code related to initializing the full LLDB suite lives directly
in API now. Previously it was only referenced from API, but because
it was defined in lldbCore, it would get implicitly linked against
by everything including lldb-server, causing a considerable
increase in binary size.
By moving this to the API layer, it also creates a better layering
for the ongoing effort to make the embedded interpreter replacable
with one from a different language (or even be completely removeable).
One semantic change necessary to get this all working was to remove
the notion of a shared debugger refcount. The debugger is either
initialized or uninitialized now, and calling Initialize() multiple
times will simply have no effect, while the first Terminate() will
now shut it down no matter how many times Initialize() was called.
This behaves nicely with all of our supported usage patterns though,
and allows us to fix a number of nasty hacks from before.

This resubmits r230380. The primary cause of the failure was
actually just a warning, which we can disable at the CMake level
in a followup patch on the LLVM side. The other thing which was
actually an error on the bot should be able to be fixed with
a clean.

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.
llvm-svn: 230380
Previously the CMake had a lot of duplication for the public API
due to some differences regarding how we link on Windows. This
fixes the issue, so making changes to the public API should be
much easier now.

Reverting this commit led to other failures which I did not see at
first. This turned out to be an easy problem to fix, so I added
SBVariablesOptions.cpp to the CMakeLists.txt. In the future please
try to make sure new files are added to CMake.
llvm-svn: 229516
We talked about it internally - and came to the conclusion that it's time to have an options class
This commit adds an SBVariablesOptions class and goes through all the required dance

CMake build of any part of LLVM with LLDB checked out fails immediately.
=[
We appear to not even have a build bot covering the CMake build of LLDB
which makes this truly terrible. That needs to be fixed immediately.

See http://reviews.llvm.org/D4221 for details.
This commit allows you to control the signals that lldb will suppress, stop or forward using the Python and C++ APIs.

Xcode build system changes (and any mistakes) by Todd Fiala. Tested on MacOSX 10.9.3 and Xcode 6 beta. (Xcode 5 is hitting the dependency checker crasher on all my systems).

The many many benefits include:
1 - Input/Output/Error streams are now handled as real streams not a push style input
2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)
We will need to deal with and fix any buildbot failures and tests and arise now that input/output and error are correctly hooked up in all cases.

libdispatch aka Grand Central Dispatch (GCD) queues. Still fleshing out the
documentation and testing of these but the overall API is settling down so it's
a good time to check it in.

- generate-vers.pl has to be called by cmake to generate the version number
- parallel builds not yet supported; dependency on clang must be explicitly specified
Tested on Linux.
- Building on Mac will require code-signing logic to be implemented.
- Building on Windows will require OS-detection logic and some selective directory inclusion
Thanks to Carlo Kok (who originally prepared these CMakefiles for Windows) and Ben Langmuir
who ported them to Linux!
