The small_query parameter for SMB_VFS_DISK_FREE() was, prior to the
previous commit, used to obtain 16-bit wide free-space information for
the deprecated dskattr SMB_COM_QUERY_INFORMATION_DISK command.
With the dskattr handler now performing the 16-bit collapse directly,
the small_query parameter can be removed from the entire code path.

With the notify code I've hit another case where self-sends caused
a problem. This time messages were lost because we tried to do
multiple dispatch_rec calls from within a single inotify callback.
Only the first one was being taken care of, the others did not find
receivers.
This patch makes self-sends go through the kernel as well, the
kernel queues everything nicely for us. With dgram messaging this
should be pretty fast. If it turns out to be a performance problem,
we can solve it later by doing proper queueing in user space. We
need to completely decouple any processing from callbacks.

With this pair of programs I did some performance tests of the messaging
system. Guess what -- I found two bugs :-)
See the subsequent patches.
With 1500 msg_source processes I can generate message overload: A
Intel(R) Xeon(R) CPU L5640 @ 2.27GHz
can receive roughly 100k messages per second. When using
messaging_read_send/recv user/system time is roughly even, a bit more
work done in user space. When using messaging_register, due to less
malloc activity, user space chews a lot less.
By the way: 1.500 helper threads in a blocking sendto() against a single
datagram socket reading as fast as it can (with epoll_wait in between)
only drove the loadavg to 12 on a 24-core machine. So I guess unix domain
datagram sockets are pretty well protected against overload. No thundering
herd or so. Interestingly "top" showed msg_sink at less than 90% CPU,
although it was clearly the bottleneck. But that must be a "top" artifact.

This is a testcase for the rpc-style messaging nested event context. We have to
fork here: The nested event context does not reply to the PING message, it only
listens for the PONG response. But that's the point of the patches: Correctly
pick just one message in a nested event context. I think this is the best we
can do with nested event contexts.

In the messaging_read receivers we already defer the callback: We need to
reply on potentially different tevent contexts, thus the defer_callback.
The callback case in messaging_dispatch_rec was direct before this
patch. This changes messaging_dispatch_rec to also defer the callback
in the self-send case.
Now we need only two roundtrips in local-messaging-read1 :-)
