Support a new CLANG_LIBRARY_PATH environment variable for the Python
binding tests. This variable can be used to force the bindings to load
libclang.* from a specific directory.
I plan to use this when integrating Python binding tests with the CMake
build system. Currently, those tests load libclang.so from default
search paths, so I would have to rely on platform-specific mechanics
such as LD_LIBRARY_PATH. Instead of copying the whole logic necessary
to handle platform differences into yet another place, it's easier to
just add a dedicated variable for this purpose.

Rewrite the tests from using plain 'assert' mixed with some nosetests
methods to the standard unittest module layout. Improve the code
to use the most canonical assertion methods whenever possible.
This has a few major advantages:
- the code uses standard methods now, resulting in a reduced number
of WTFs whenever someone with basic Python knowledge gets to read it,
- completely unnecessary dependency on nosetests is removed since
the standard library supplies all that is necessary for the tests
to run,
- the tests can be run via any test runner, including the one built-in
in Python,
- the failure output for most of the tests is improved from 'assertion
x == y failed' to actually telling the values.

Bendersky. Specifically:
* Implemented a new function in libclang: clang_isAttribute
* Fixing TranslationUnit.get_includes to only go through the argument
* buffer when it contains something. This fixed a crash on Windows
* clang_getFileName returns CXString, not char*. Made appropriate
* fixes in cindex.py - now the relevant tests pass and we can see the
* full locations correctly again (previously there was garbage in
* place of the file name)
* Exposed clang_getCursorDisplayName to the python bindings
