606398a3a6 s3: VFS: Add SMB_VFS_RENAMEAT().
Currently identical to SMB_VFS_RENAME() - uses
AT_FDCWD for both src and dst directories.

Next, move add to all VFS modules that implement
rename and eventually remove rename.

13921645c4 smbd: Remove "share_access" from files_struct
Nobody used this (except vfs_gpfs, which did not need it really). If
you *really* need this, you can always look in locking.tdb, but this
should never happen in any hot code path, as no runtime decisions are
made on the share access after the open is done.

Bump VFS interface number to 42.

fbbf684338 smbd: Add smbd_smb1_do_locks_send/recv()
This contains the SMB1-specific brlock logic. Right now our core
brlock code has specialized code to deal with pending locks. For
dealing with pending requests waiting for something nowadays we
recommend to use tevent_req. This code also provides the basis to
remove the SMB1 special case handling from the core logic, isolating
protocol features specific to SMB1 and not exposed in SMB2 in
SMB1-specific code.

The core brlock code will not see blocking locks anymore. Instead, the
code in this patch will always immediately fail and take care of the
retries and timeouts.

Retries are implemented by a dbwrap_watch_record_send on the
corresponding locking.tdb entry. A later commit will make unlocks
trigger wakeups there. I chose locking.tdb and not brlock itself to
simplify the implementation. We already have oplock break watchers on
locking.tdb, this will only add one more. This might lead to spurious
wakeups, but they are taken care of by careful retries. An advantage
of doing that is the implicit handling of a killed blocker PID through
dbwrap_watch, obsoleting brl_revalidate.

This will be used to streamline the use of impersonating wrappers

This will allow us to introduce path based async operations
to the SMB_VFS layer.
