Break up the passdb objects (to allow RPC clients to link without brining in

*.o) and implment new enum_dom_users code in the SAMR RPC subsystem.

Incresingly, we are using the pdb_get_{user,group}_sid() functions, in the
eventual hope that we might one day support muliple domains off a single
passdb.  To extract the RID, we use sid_peek_check_rid(), and supply an
'expected' domain SID.

The id21 -> SAM_ACCOUNT and id23 -> SAM_ACCOUNT code has been moved to
srv_samr_util.c, to ease linking in passdb users.

Compatiblity code that uses 'get_global_sam_sid()' for the 'expected' sid is in
pdb_compat.c
