r4724: Add support for Windows privileges in Samba 3.0
(based on Simo's code in trunk). Rewritten with the following changes: * privilege set is based on a 32-bit mask instead of strings (plans are to extend this to a 64 or 128-bit mask before the next 3.0.11preX release). * Remove the privilege code from the passdb API (replication to come later) * Only support the minimum amount of privileges that make sense. * Rewrite the domain join checks to use the SeMachineAccountPrivilege instead of the 'is a member of "Domain Admins"?' check that started all this. Still todo: * Utilize the SePrintOperatorPrivilege in addition to the 'printer admin' parameter * Utilize the SeAddUserPrivilege for adding users and groups * Fix some of the hard coded _lsa_*() calls * Start work on enough of SAM replication to get privileges from one Samba DC to another. * Come up with some management tool for manipultaing privileges instead of user manager since it is buggy when run on a 2k client (haven't tried xp). Works ok on NT4. (This used to be commit 77c10ff9aa6414a31eece6dfec00793f190a9d6c)
