gfapi.py: support dynamic loading of versioned librariesv3.4.2qa5
Currently gfapi.py only loads libraries by filename ending in ".so". On an installed system without development packages, the <lib>.so filenames are not available. ctypes.util.find_library() can be used to detect the files dynamically. In addition to this, also fixing some minor indention errors and package the library into the Python site-packages path. Python applications and libraries can now access libgfapi through 'from glusterfs import gfapi'.
