ctdb: Introduce buffer.offset to avoid memmove
The memmove operation is quite expensive, therefore,
a new buffer attribute "offset" is introduced to support
an optimized buffer processing.
The optimization is to "walk" through the buffer and process
each packet until the buffer is fully processed (empty)
without requiring any memmove.
Only if a packet is in-complete, the buffer content is moved
and the new data is read from the queue.
This way almost all memmove operations are eliminated.
librpc:ndr: Give the optimizer hints for ndr_push_bytes()
Also remove the redundant check in ndr_push_DATA_BLOB.

selftest: Don't run KCC on backup testenvs (to avoid flappiness)
KCC onthe backup domain (i.e. backupfromdc, restoredc, offlinebackupdc)
can establish new connections for replication. Depending on timing,
this can cause the join_ldapcmp test to fail, because there's an extra
object under the NTDS Settings, at the point the ldapcmp is done.
We don't need any replication to happen on the backup domain. The
backup/restore workflow in the real world should mean that the restored DC
is never run in the same network as the original DC.
This patch updates the default KCC command for the backup testenvs to be
a no-op, so the DCs won't create new connection objects.

traffic_replay: Add a max-members option to cap group size
traffic_replay tries to distribute the users among the groups in a
realistic manner - some groups will have almost all users in them.
However, this becomes a problem when testing a really large database,
e.g. we may want 100K users, but no more than 5K users in each group.
This patch adds a max-member option so we can limit how big the groups
actually get.
If we detect that a group exceeds the max-members, we reset the group's
probability (of getting selected) to zero, and then recalculate the
cumulative distribution. The means that the group should no longer get
selected by generate_random_membership(). (Note we can't completely
remove the group from the list because that changes the
list-index-to-group-ID mapping).

ctdb-daemon: Exit with error if a database directory does not exist
Since 4.9.0, the log messages can be confusing if a required database
directory does not exist. Explicitly check for database directories,
logging a clear error and exiting if one is missing.
Ie addtionally check open_access_mask against DELETE_ACCESS. As a result
opens with DELETE_ACCESS go through the code that does an fd_open() plus
a subsequent fstat().
That will trigger a crash in fruit_fstat_meta_stream() when a client
wants to delete a file for deletion. When we open base file for delete,
we call open_streams_for_delete() which internally calls create-file
with NTCREATEX_OPTIONS_PRIVATE_STREAM_DELETE which prevents opening of

This patch allows a list of shares to be specified, and only those
shares are checked, which can be much faster if you're only interested
in a few shares on a server which exports lots.
This subcommand already accepts an optional filename for the output
of net usersidlist, with a default of stdin. Typically you'd just pipe
one command to the other so stdin is most likely what you want. This

specify stdin explicitly when you provide a list of shares, since in
