prep for flex file layout server

Changes in v2:

- moved "4.1 client: reclaim_complete after create_session" to "dataserver: reclaim_complete after create_session" as the implicit reclaim complete is needed in DS path, but not in all server tests.

- dropped "4.1 server: service RECLAIM_COMPLETE operations" as it's unneeded.

- formatted these patches with -M flag so we can see moved files

.. and I pushed the changes to my ff_prep branch.

Thanks!

These patches are in preparation for the pynfs implementation of a flex file layout server.

I already have patches for a working flex file server, but I figure those should wait until the spec is complete ;)

I pushed these patches to my linux-nfs.org tree on branch 'ff_prep':

git://git.linux-nfs.org/projects/dros/pynfs.git

The prep includes:

- patches that enable pynfs mds using real v4.1 DSes (on the backend, not usable from clients as there is no stateid sharing between mds and ds)

- fix several bugs in pnfs path

- move .x files to subdir 'xdrdef' - the nfs4.1 directory was getting crowded and we're going to add several more .x files along with all of the autogenerated files. Note this change touches server tests too.

- clean up the nfs4server's output - no longer print out EVERY part of EVERY operation which was very efficient at hiding tracebacks and made pynfs even slower. Old functionality is now switched on with -v flag. Also added an in-between mode "-s" that prints a summary of whats going on.

- support for NFSv3 backend communication - this is not actually used yet, but can be tested with file layout by always returning NFS4ERR_LAYOUTUNAVAILABLE in layoutget and using DataServer3 class instead of DataServer41

Weston Andros Adamson (16):
dataserver: reclaim_complete after create_session
dataserver: only catch connection error 4.1 server: avoid traceback in DS disconnect() move .x files to subdir 'xdrdef'
4.1 client: remove unused imports
4.1 server: add -v flag & silence random output 4.1 server: add -s option to print summary of ops
dataserver: make generic interface to ops
dataserver: don't import * from nfs4 specific mods 4.1 server: move nfs4_ops.py to nfs_ops.py add mntv3, portmapv2 and nfsv3 .x files
dataserver: separate generic and 4.1 code 4.1 server: add support for NFSv3 data servers 4.1 server: get rid of old op_getdeviceinfo
rpc: on socket error, close and mark pipe inactive
nfs3clnt: reconnect when sending on inactive pipe
