Bug fix for pr18841:
http://llvm.org/bugs/show_bug.cgi?id=18841
This change creates a stub Python readline.so module that does almost
nothing. Its whole purpose is to prevent Python from loading the real
module, something it does during the embedded Python interpreter's
initialization sequence (and way before lldb ever requests it within
embedded_interpreter.py).
On Ubuntu 12.04 and 13.10 x86_64, and in the Python 2.7.6 tree, the
stock Python readline module links against the GNU readline library.
This appears to be the case on all Pythons except where __APPLE__ is
defined. LLDB now requires linking against the libedit library.
Something about having both libedit.so and libreadline.so linked into
the same process space is causing the Python readline.so to trigger a
NULL memory access. I have put in a separate patch to python.org.
This suppression of embedded interpreter readline support can be
removed if at least any one of the following happens:
1. The stock python distribution accepts a patch similar to what I
submitted to Python 2.7.6's Modules/readline.c file.
2. The stock python distribution implements Modules/readline.c in
terms of libedit's readline compatibility mode (i.e. essentially
compiles it the way __APPLE__ compiles that module) under Linux.
3. a clean-room implementation of the python readline module is
implemented against libedit (either readline compatibility mode or
native libedit). This could be implemented within the readline.cpp
file that this change introduces. It cannot be a fork of python's
readline.c module due to llvm licensing.
The net effect of this change on Linux is that the embedded python's
readline support will not exist.

- missing definitions were causing different definitions of type 'off_t', resulting in linker errors
- fix is to define _LARGEFILE_SOURCE and _FILE_OFFSET_BITS=64

Unbreaks the build on FreeBSD
People that are using Linux: if you have any problems with this patch
please let me know, and tell us how you are compiling lldb with the
makefiles.

a new POSIX platform. It also contains fixes for 64bit FreeBSD.
The patch is based on changes by Mark Peek <mp@FreeBSD.org> and
"K. Macy" <kmacy@freebsd.org> in their github repo located at
https://github.com/fbsd/lldb.

I did not take the patch for ClangExpressionParser.cpp since there was a
recent change by Peter for the same line. Feel free to disagree. :-)

Add reloc arg to standard JIT createJIT()
Fixes non-__APPLE__ build. Patch by Matt Johnson!

Also, I ignore the part of the patch to remove the RegisterContextDarwin*.h/.cpp.

With the current target revision of Clang libclangChecker no longer exists and
is not needed. Update the include path so we can get at ARM_DWARF_Registers.h
and friends.

In particular, we are looking to ignore the "#pragma mark" construct which GCC
warns about on platforms other than Darwin. This cleans up diagnostic output
significantly.

enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.
