We only have one messaging_dgm context per process. But we will use this from
two completely independent messaging subsystems which are independently
initialized. We need to coordinate creation and destruction, do this via
talloc.
I know this looks like a step back, but when in the future we have really just
one messaging subsystem, this can go again. My immediate goal is to make
source3 and source4 transport-compatible, and this looks like a quick way
towards that goal.

This is a little set of routines to deal with the ugly fd-passing macros.
This patch is the first step assisting the creation of msghrds for sending fds.
Receiving fd helpers will follow later.
The basic idea behind these routines is that they fill a variable-sized buffer.
They are supposed to be called twice per msghdr preparation. First with a
0-sized NULL output buffer to calculate the required bufsize, and then a second
time filling in the buffer as such.
This does not take care of the old msg_accrights way of passing file
descriptors. CMSG/SCM_RIGHTS is standardized for quite a while now, and I
believe this intreface can be made to also take care of msg_accrights if
needed.

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 patch seems odd, but the pdb_samba_dsdb module has exactly this
semantics. That is, the pdb_samba_dsdb is responsible for all IDMAP
values, due to backing on to the idmap.ldb allocator. This option is
added so we can continue to support the mappings written into that
database even when switching winbindd implementations - the source4/
winbind code would only ask the idmap_ldb code, no matter what the
SID.
Almost all of the behaviour for this is already in winbindd, but we
need this extra flag function so as to avoid (currently intentional)
errors at startup due to not having a per-domain allocation
configured in the smb.conf.

Messaging based on unix domain datagram sockets
This makes every process participating in messaging bind on a unix domain
datagram socket, similar to the source4 based messaging. The details are a bit
different though:
Retry after EWOULDBLOCK is done with a blocking thread, not by polling. This
was the only way I could in experiments avoid a thundering herd or high load
under Linux in extreme overload situations like many thousands of processes
sending to one blocked process. If there are better ideas to do this in a
simple way, I'm more than happy to remove the pthreadpool dependency again.
There is only one socket per process, not per task. I don't think that per-task
sockets are really necessary, we can do filtering in user space. The message
contains the destination server_id, which contains the destination task_id. I
think we can rebase the source4 based imessaging on top of this, allowing
multiple imessaging contexts on top of one messaging_context. I had planned to
do this conversion before this goes in, but Jeremy convinced me that this has
value in itself :-)
Per socket we also create a fcntl-based lockfile to allow race-free cleanup of
orphaned sockets. This lockfile contains the unique_id, which in the future
will make the server_id.tdb obsolete.

This is a messaging layer based on unix domain datagram sockets.
Sending to an idle socket is just one single nonblocking sendmsg call. If the
recv queue is full, we start a background thread to do a blocking call. The
source4 based imessaging uses a polling fallback. In a situation where
thousands of senders beat one single blocked socket, this will generate load on
the system due to the constant polling. This does not happen with a threaded
blocking send call.
The threaded approach has another advantage: We save become_root() calls on the
retries. The access checks are done when the blocking socket is connected, the
threaded blocking send call does not check permissions anymore.
