gluster: add fallocate fop support
Implement support for the fallocate file operation. fallocate
allocates blocks for a particular inode such that future writes
to the associated region of the file are guaranteed not to fail
with ENOSPC.
This patch adds fallocate support to the following areas:
- libglusterfs
- mount/fuse
- io-stats
- performance/md-cache,open-behind
- quota
- cluster/afr,dht,stripe
- rpc/xdr
- protocol/client,server
- io-threads
- marker
- storage/posix
- libgfapi
