rpc: split FOPs enum from glusterfs.h

Moving the enumeration of FOPs and some of the other parts that are
defining the network protocol to the rpc/xdr/ section. These structures
need some care when modifications are made, moving them out of the
common glusterfs.h header helps with that.

The protocol definition structures are generated in a new glusterfs-fops
header. This file is present in rpc/xdr/src/ and libglusterfs/src/, it
is a little ugly, but prevents the need to update all Makefile.am files
with the additional -I option for finding the new header file.

The generation of the .c and .h files from the .x descriptions needed
small modifications to accommodate these changes. The build/xdrgen
script was improved slightly for this. The .c and .h files are
incorrectly in the $(top_srcdir), instead of $(top_builddir). This is
an existing issue, and bug 1330604 has been filed to get that addressed.
