r4805: Last planned change to the privileges infrastructure:
* rewrote the tdb layout of privilege records in account_pol.tdb (allow for 128 bits instead of 32 bit flags) * migrated to using SE_PRIV structure instead of the PRIVILEGE_SET structure. The latter is now used for parsing routines mainly. Still need to incorporate some client support into 'net' so for setting privileges. And make use of the SeAddUserPrivilege right. (This used to be commit 41dc7f7573c6d637e19a01e7ed0e716ac0f1fb15)
