53258e6f9e [python] Fix getting section contents.
The returnvalue was handled as c_char_p which ment that ctypes
handled it as a NUL-terminated string making it cut the contents
at first NUL (or even worse - overrunning the buffer if it doesn't
contain a NUL).

7426771280 Convert getFileOffset to getOffset and move it to its only user.
We normally don't drop functions from the C API's, but in this case I think we
can:

* The old implementation of getFileOffset was fairly broken
* The introduction of LLVMGetSymbolFileOffset was itself a C api breaking
  change as it removed LLVMGetSymbolOffset.
* It is an incredibly specialized use case. The only reason MCJIT needs it is
  because of its odd position of being a dynamic linker of .o files.

e8a957d2a9 python: Fix check for disasm creation failure
Check should be for pointer being NULL, not what it points to.

Also adds a test for this case.

60e4d7f618 python: Properly initialize before trying to create disasm
As the "LLVMInitializeAll*" functions are not available as symbols in
the shared library they can't be used, and as a workaround a list of
the targets is kept and the individual symbols tried. As soon as the
"All"-functions are changed to proper symbols (as opposed to static
inlines in the headers) this hack will be replace with simple calls
to the corresponding "LLVMInitializeAll*" functions.

653212fdd1 [python bindings] Added code to get the length of a memory buffer. Tests are included.
This is a part of a series of patches that have been sitting fallow on a
personal branch that I have been messing with for a bit.

The patches start to flesh out the python llvm-c wrapper to the point where you can:

1. Load Modules from Bitcode/Dump/Print them.
2. Iterate over Functions from those modules/get their names/dump them.
3. Iterate over the BasicBlocks from said function/get the BB's name/dump it.
4. Iterate over the Instructions in said BasicBlocks/get the instructions
   name/dump the instruction.

My main interest in developing this was to be able to gather statistics about
LLVM IR using python scripts to speed up statistical profiling of different IR
level transformations (hence the focus on printing/dumping/getting names).

This is a gift from me to the LLVM community = ).

I am going to be committing the patches slowly over the next bit as I have time
to prepare the patches.

The overall organization follows the c-api like the bindings that are already
implemented.

17cfe87c39 [python] fix get_library()
Before this fix, the LLVM Python bindings on SVN trunk always fail with:
	Exception: LLVM shared library not found!
since it's still looking for a library named "LLVM-3.1svn".

Besides updating the LLVM version in the library name,
this patch also changes llvm.get_library() to make it possible to run
the unit tests without installing the LLVM shared library into a
default linker search path.

e.g. after this patch, running the llvm/python unit tests with:
LD_LIBRARY_PATH=../build/Debug+Asserts/lib nosetests -v bindings/python/llvm/tests/
would work on Linux.

Patch from Scott Tsai (with some minor modifications)

0b3aae906f [llvm.py] Implement interface to enhanced disassembler
This requires a C++ change to EDDisassembler's ctor to function properly
(the llvm::InitializeAll* functions aren't being called currently and
there is no way to call them from Python).

Code is partially tested and works well enough for initial commit. There
are probably many small bugs.

5ae04279e0 [llvm.py] Initial skeleton for Python LLVM bindings
This contains a semi-functional skeleton for the implementation of the
LLVM bindings for Python.

The API for the Object.h interface is roughly designed but not
implemented. MemoryBufferRef is implemented and actually appears to
work!

The ObjectFile unit test fails with a segmentation fault because the
LLVM library isn't being properly initialized. The build system doesn't
know about this code yet, so no alerts should fire.
