Move source files into gfapi/ dir

Currently, many source files are directly placed under gluster/ dir:
gluster/exceptions.py
gluster/gfapi.py
gluster/utils.py

When multiple packages (RPMs) are sharing the same gluster namespace,
these source files will conflict if there are source files with same
names provided by other projects.

Fix: Move all source files in gluster/* to gluster/gfapi/*
Note that this patch does not break how existing users import gfapi.

-# Wow, the Linux kernel folks really play nasty games with this structure.  If

-# fact that's exactly how they're defined *for 64-bit systems*; for 32-bit
-# they're in the man-page order.  Even uglier, the man page makes no mention of
-# the *nsec fields, but they are very much present and if they're not included
-# then we get memory corruption because libgfapi has a structure definition
-# that's longer than ours and they overwrite some random bit of memory after
-# the space we allocated.  Yes, that's all very disgusting, and I'm still not
-# sure this will really work on 32-bit because all of the field types are so
