glusterfs-fops: fix the modularity

glusterfs-fops.h was moved to rpc/xdr to support compound fops.
(ref: https://review.gluster.org/14032, 2f945b86d3)

This was fine as long as all these header files were in single
include directory after 'install'. With the move to separate out
glusterfs specific header files into another directory inside
/usr/include (ref: https://review.gluster.org/21746, 20ef211cfa),
glusterfs-fops.h file was not in the proper path when an external
.c file tried to include any of glusterfs specific .h file (like
xlator.h).

Now, we have removed compound-fops, with that, none of the enums
declared in glusterfs-fops.h are actually getting used on wire
anymore. Hence, it makes sense to get this to libglusterfs/src
as a single point of definition. With this change, the external
programs can use glusterfs header files.

also remove some enum definitions which are not used in code
anymore.
