chgpasswd.c: Added comments to #ifdefs

ipc.c: Caused samba password changing not to be done if UNIX password
       changing requested and not successful.
util.c: Added string_to_sid() and sid_to_string() functions.
lib/rpc/client/cli_samr.c:

lib/rpc/server/srv_util.c: Changes so that instead of passing SIDs
around as char *, they are converted to DOM_SID at the earliest
opportunity, and passed around as that. Also added dynamic memory
allocation of group sids. Preparing to auto-generate machine sid.
Jeremy.
