Windows Server starts some named pipe services on demand, and responds
to initial open requests with STATUS_PIPE_NOT_AVAILABLE. The FssagentRpc
named pipe on Windows Server 2012 exhibits this behaviour.
This change sees rpcclient retry named pipe open requests when the
server responds with STATUS_PIPE_NOT_AVAILABLE. The retry logic is
contained in an asynchronous tevent_timer callback, to allow for
non-blocking callers.

If the same process tries to re-lock the same record
it has already locked, don't go to the ctdbd again.
There are situations where we already have a lock on a record
and then do a dbwrap_parse_record() on that record, for instance
in locking code:
do_lock()
-> grabs lock on brl record with brl_get_locks()
-> calls brl_lock()
-> calls brl_lock_posix or _windows_default()
-> calls contend_level2_oplocks_begin()
-> calls brl_locks_get_read_only()
-> calls dbwrap_parse_record on the same brl record as above
In the local (tdb) case, this is not a problem, because
identical fcntl locks in the same process don't contend each other,
but calling out to ctdb for this lets smbd and ctdb deadlock.
db_ctdb_fetch_lock() already correclty checks first
whether we can simply try to lock locally. But db_ctdb_parse_record()
failed to do so for empty records, i.e. records that only
consist of the ctdb record header. (These can be deleted records
but can also be freshly created and still empty records.)
This patch lets db_ctdb_parse_record() not skip local access
for empty records, hence fixing the deadlock.
PLAN: In the long run, it would be better to solve this
generically on the dbwrap_layer, i.e. root the notion of
an already locked record there, and skip any call to the
db (tdb or ctdb backend) if we have it. This would also
solve the problem for all calls like fetch_locked, parse_record
and possibly others. But this is the urgent fix for now.

brl_get_locks_readonly() currently returns NULL when it can't
find any byte range locks on the file. This is an error - it
should return a valid struct byte_range_lock containing num_locks == 0
so it can be cached.
Returning NULL when there are no locks causes POSIX lock
tests to fail returning NT_STATUS_NO_MEMORY (as it thinks
it can't allocate the struct) instead of NT_STATUS_OK.

This doesn't implement what was recommended. That would require
