This walks brlock.tdb, which can be time-consuming.
This adds a new includes.h include. It's too much of a pain for me now to
make locking/proto.h clean to include on its own.

The consolidation will soon be done by a separate process. We need to
avoid the getpid() call in smbprofile_cleanup().

We do way too much stuff in the parent smbd in remove_child_pid(). In
particular accessing ctdbd is not a good idea when ctdbd is stuck in something.
We've had a case where smbd exited itself with "ctdb timeout" being set to 60
seconds. ctdb was just stuck doing recoveries, and the parent smbd was sitting
in serverid_exists trying to retrieve a record for a child that had exited. Not
good.
This daemon sits there as parent->cleanupd and receives MSG_SMB_NOTIFY_CLEANUP
messages that hold the serverid and exit status of a former child. The next
commits will step by step empty remove_child_pid in the parent and move the
tasks to the helper.

Removes accessor functions as now this parameter is set
under user control in smb.conf. Default is 100.
Note that this doesn't limit the number of outstanding
aio requests, it just causes them to go onto the
pthreadpool queue.
Now we need to prioritize pthreadpool pipe replies
ahead of incoming SMB2 requests, but that's a patch
for another day.
Based on ideas from Volker.

SMB2 FLUSH mainly calls fsync and there is already code in place to
handle fsync asynchronously, so use the asynchronous code path for SMB2
FLUSH. This avoids a SMB2 FLUSH stalling other requests processing.

This is not what Windows server does, but it seems that Windows
clients expect. Windows->Windows never runs into this issue, because
an encryption-enabled SMB3 connection will always use leases, and lease
breaks *are* unencrypted...
You can reproduce the issue Windows->Windows by disabling leases on the
Windows server. Disable leases using the registry key:
HKLM\SYSTEM\CurrentControlSet\Services\LanmanServer\DisableLeasing
Dochelp confirmed that this is a valid workaround for Windows clients
dropping encrypted oplock breaks.

The array is uint16, doubling the file name length consumes twice the space
required.
As we're hand assembling this as a series of concatinated individual data_blobs,
we must take care to ensure the correct 4 byte alignment that was
being masked by the previous doubling of the filename length.
