NULL
Suppose the get_xlator_by_name returns NULL and the connection is put back
then update the xl_private of the transport by setting to NULL. Otherwise
server_connection_put would have freed the connection object and xl_private
of the transport would still be pointing to the same location which is
freed, thus leading to a segfault when the location is accessed.

If getting bound_xl fails, then while putting the connection back we
should also check for bound_xl pointer for NULL apart from the op_ret
and the connection object. We were checking just op_ret and conn pointer
till now and if the mount from a machine is not allowed as auth.allow
did not permit it, then also we were destroying the connection object.

This patch fixes the success check for xdr_to_generic function across the
codebase.
Also, cleans up the brick_op actors table in glusterfsd-mgmt.c to make sure that
the actors are called directly by rpcsvc.

In server_setvolume, put the connection back (thus removing it
from a the list of connections that protocol/server is maintaining
if the connection object is a newly created one) if some operations
such as getting the bound_xl etc fails. Otherwise the process might
segfault upon statedump, when it tries to access NULL bound_xl of a
connection.

If there is a disconnect observed on the client when the
inode/entry unlock is issued, but the reconnection to server
happens with in the grace-time period the inode/entry lk will
live and the unlock will never come from that client.
The internal locks should be cleared on disconnect.

1) Adding the connection to conf->conns used to
happen in conf->mutex, but removing happened under conn->lock.
Fixed that as below.
When the connection object is created conn's ref, bind_ref count
is set to '1'. For bind_ref ref/unref happens under conf->mutex
whenever server_connection_get, put is called.
When bind_ref goes to '0' connection object is removed from
conf->conns under conf->mutex. After it is removed from the list,
conn_unref is called outside the conf->mutex.
conn_ref/unref still happens under conn->lock.
2) Fixed races in server_connection_cleaup in grace_timer_handler
and server_setvolume.

Currently(with out this patch), on a disconnect the server cleans up
the transport which inturn closes the fd's and releases the locks acquired on
those fd's by that client. On a reconnect, client just reopens the fd's but
doesn't reacquire the locks. The application that had previously acquired
the locks still is under the assumption that it is the owner of those locks
which might have been granted to other clients(if they request) by the server
leading to data corruption.
This patch allows the client to reacquire the fcntl locks (held on the fd's)
during client-server handshake.
* The server identifies the client via process-uuid-xl (which is a combination
of uuid and client-protocol name, it is assumed to be unique) and lk-version
number.
* The client maintains a list of process-uuid-xl, lk-version pair for each
accepted connection. On a connect, the server traverses the list for a
matching pair, if a matching pair is not found the the server returns
lk-version with value 0, else it returns the lk-version it has in store.
* On a disconnect, the server and client enter grace period, and on the
completion of the grace period, the client bumps up its lk-version number
(which means, it will reacquire the locks the next time) and the server will
distroy the connection. If reconnection happens within the grace period, the
server will find the matching (process-uuid-xl, lk-version) pair in its list
which guarantees that the fd's and there corresponding locks are still valid
for this client.
Configurable options:
To set grace-timeout, the following options are
option server.grace-timeout value
option client.grace-timeout value
To enable or disable the lk-heal,
option lk-heal [on|off]
gluster volume set command can be used to configurable options

* As RPC program's name is just used for logging, we now have
'PACKAGE_VERSION' part of the string, which gets logged in client
side.
* From client, we send the PACKAGE_VERSION in handshake dictionary,
which gets logged on serverside handshake.
The change doesn't break any compatibility between client or server
as it would only enhance the logging part of handshake.

Earlier:
step 1: copy the existing <xdr>.x files to /tmp
step 2: generate '.[ch]' files using 'rpcgen <xdr>.x'
step 3: check diff with the to the existing files, add only your part
of changes back to the original file. (ignore other changes).
step 4: there is another file to write wrapper functions to convert
structures to/from XDR buffers, update it with your new structure.
step 5: use these wrapper functions in the newly written procedures.
step 6: commit :-|
Now:
step 1: update (mostly adding only) the <xdr>.x file
step 2: run '<path-to-src>/extras/generate-xdr-files.sh <xdr>.x' command
step 3: implement rpc procedure to handle the request/response.
step 4: commit :-)
