Michael Adam 6090601c8b r23485: This checkin consists mostly of refactorings in preparation of the
activation of global registry options in loadparm.c, mainly to
extract functionality from net_conf.c to be made availabel elsewhere
and to minimize linker dependencies.

In detail:

* move functions registry_push/pull_value from lib/util_reg.c to new file
  lib/util_reg_api.c

* create a fake user token consisting of builtin administrators sid and
  se_disk_operators privilege by hand instead of using get_root_nt_token()
  to minimize linker deps for bin/net.

  + new function registry_create_admin_token() in new lib/util_reg_smbconf.c
  + move dup_nt_token from auth/token_util.c to new file lib/util_nttoken.c
  + adapt net_conf.c and Makefile.in accordingly.

* split lib/profiles.c into two parts: new file lib/profiles_basic.c
  takes all the low level mask manipulation and format conversion functions
  (se_priv, privset, luid). the privs array is completely hidden from
  profiles.c by adding some access-functions. some mask-functions are not
  static anymore.

  Generally, SID- and LUID-related stuff that has more dependencies
  is kept in lib/profiles.c

* Move initialization of regdb from net_conf.c into a function
  registry_init_regdb() in lib/util_reg_smbconf.c.
