r7938: * move the hardcoded registry value names from _reg_query_value()

  to a thin layer in fetch_reg_values().  Not entirely efficient
  seeing as the the dynamic value paths are stored in an unsorted
  array but it is one strequal() per path.  If this was really big
  it should be worked into the reghook_cache().
(This used to be commit 63b81ad3cb484090a181fbd13e04922a5c17e7d9)
