fix the messaging code to call the efficient calls :
save_re_uid()
set_effective_uid(0);
messaging_op
restore_re_uid();
instead of using heavyweight become_root()/unbecome_root()
pairs around all messaging code. Fixup the messaging
code to ensure sec_init() is called (only once) so that non-root
processes still work when sending messages.
This is a lighter weight solution to become_root()/unbecome_root()
(which swaps all the supplemental groups) and should be more
efficient. I will migrate all server code over to using this
(a similar technique should be used in the passdb backend
where needed).

This allows a requestor to set FORCE_OPLOCK_BREAK_TO_NONE
to ensure we don't break to level 2. Fixed a couple
of resource leaks in error paths in open_file_ntcreatex.

fsp pointers. Ensure we cope with this to pass Samba4
DENY tests (we used to pass these, there must have been
a regression with newer code). We now pass them.

always linearize into little-endian. Should fix all
Solaris issues with this, plus provide a cleaner base
moving forward for cluster-aware Samba where smbd's
can communicate across different compilers/architectures
(eventually these message will have to go cross-machine).
Jeremy.
revving the minor version number for libsmbsharemodes (we
now have a new _ex interface that takes the share path
as well as the filename). Needed for #3303. Some code written
by SATOH Fumiyasu <fumiya@samba.gr.jp> included in the changes
to locking/locking.c. The smbstatus output is a bit of a mess
and needs overhauling...

* \PIPE\unixinfo
* winbindd's {group,alias}membership new functions
* winbindd's lookupsids() functionality
* swat (trunk changes to be reverted as per discussion with Deryck)
tests on this as it's very late NY time (just wanted to get this work
into the tree). I'll test this over the weekend....
Jerry - in looking at the difference between the two trees there
seem to be some printing/ntprinting.c and registry changes we might
want to examine to try keep in sync.

new function to make it clear when it's called. Remove async parameter
that had been overloaded into request_oplock_break.
Inspired by work from Nadav Danieli <nadavd@exanet.com>.

message, or we mess up the signing sequence number.... Also improve sign error
reporting. Also when deferring an open that had been deferred due to an oplock
break, don't re-add the mid to the pending sign queue or we increment the sequence
number twice and mess up signing again...
I can now bounce between 2 WinXP/Win2003 boxes opening Excel spreadsheets with
signing turned on and get correct "file in use" messages.
Jeremy.
I was storing the mid of the oplock break - I should have been
storing the mid from the open. There are thus 2 types of deferred
packet sequence returns - ones that increment the sequence number
(returns from oplock causing opens) and ones that don't (change notify
returns etc). Running with signing forced on does lead to some
interesting tests :-).
Jeremy.
level 2 and a request for open with no oplock is received then the
smbd should send *synchronous* break messages, not asynchronous,
otherwise it spins very rapidly, releasing the lock, sending the
'break to none' messages and then re-acquiring the lock before
any other process has a chance to get the lock and remove it's own
oplock (at least on linux).
