The Linux kernel has a bug in that it can give spurious
wakeups on a non-blocking UDP socket for a non-deliverable packet.
When nmbd was changed to use non-blocking sockets it
became vulnerable to a spurious wakeup from poll/epoll.
Fix sys_recvfile() to return on EWOULDBLOCK/EAGAIN.

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.

The current messaging implementation is based on a tdb indexed by server_id. If
we have more than one messaging context in a process, messages might not arrive
at the right context and be dropped, depending on which signal handler is
triggered first.
This is the same patch as bd55fdb lifted to messaging.c

The only reason why this could fail is a severe ctdb communications
problem. The normal way to deal with this is ctdb_fatal. This avoids a
confusing panic in get_share_mode_lock when ctdb is shutdown while this
call happens.

default_sys_recvfile() and splice() recvfile were not
written to cope with non-blocking sockets.
When either the socket read() or splice() return
-1 with errno EWOULDBLOCK or EAGAIN, if no bytes have been
processed yet, return -1 and let the caller set
blocking and retry. If bytes have been processed,
just return them as a short read and let the
caller retry with the remaining needed reads.

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 :-)

If we register an additional tevent context, we can now properly do
nested event contexts, listening for just one message type inside a
tevent_req_poll.
At this point this only enhances things without ctdb, but I'm working fixing
that soon.

With this patch it will be possible to use nested event contexts with
messaging_filtered_read_send/recv. Before this patchset only the one and only
event context a messaging_context is initialized with is able to receive
datagrams from the unix domain socket. So if you want to code a synchronous
RPC-like operation using a nested event context, you will not see the reply,
because the nested event context does not have the required tevent_fd's.
Unfortunately, this patchset has to add some advanced array voodoo. The idea
is that state->watches[] contains what we hand out with watch_new, and
state->contexts contains references to the tevent_contexts. For every watch we
need a tevent_fd in every event context, and the routines make sure that the
arrays are properly maintained.
