Converting those types to unsigned should help in
creating DRSUAPI dissector for Wireshark also.

When a samba server process dies hard, it has no chance to clean up its entries
in locking.tdb, brlock.tdb, connections.tdb and sessionid.tdb.
For locking.tdb and brlock.tdb Samba is robust by checking every time we read
an entry from the database if the corresponding process still exists. If it
does not exist anymore, the entry is deleted. This is not 100% failsafe though:
On systems with a limited PID space there is a non-zero chance that between the
smbd's death and the fresh access, the PID is recycled by another long-running
process. This renders all files that had been locked by the killed smbd
potentially unusable until the new process also dies.
This patch is supposed to fix the problem the following way: Every process ID
in every database is augmented by a random 64-bit number that is stored in a
serverid.tdb. Whenever we need to check if a process still exists we know its
PID and the 64-bit number. We look up the PID in serverid.tdb and compare the
64-bit number. If it's the same, the process still is a valid smbd holding the
lock. If it is different, a new smbd has taken over.
I believe this is safe against an smbd that has died hard and the PID has been
taken over by a non-samba process. This process would not have registered
itself with a fresh 64-bit number in serverid.tdb, so the old one still exists
in serverid.tdb. We protect against this case by the parent smbd taking care of
deregistering PIDs from serverid.tdb and the fact that serverid.tdb is
CLEAR_IF_FIRST.
CLEAR_IF_FIRST does not work in a cluster, so the automatic cleanup does not
work when all smbds are restarted. For this, "net serverid wipe" has to be run
before smbd starts up. As a convenience, "net serverid wipedbs" also cleans up
sessionid.tdb and connections.tdb.
While there, this also cleans up overloading connections.tdb with all the
process entries just for messaging_send_all().

Also found by the WINREG torture test enhancements by gd.
|

This should let the new WINREG tests written by gd at least pass against us.

sscanf can return also on short reads, in this case an invalid escape
sequence like '\1k' would be accepted, returning 1 as value and swallowing the
'k'. Use an auxiliar function to validate and convert hex escapes.

Also add torture test to check filter parsing.

Also fix some indentations.

against Windows Server 2008
This is a reworked version of the mentioned test which passes against Windows
Server 2008. The previous version, also mainly written by me passed only against
Windows Server <= 2003.

Windows 2008
Add more security checks and other corrections to imitate Windows Server >= 2008.
