Changes:

        - Removed obsolete palloc checks, they get trapped in the
          alloc.c

        - Removed static msql-err string claim (to make future treading
          easier; although the linked in libmsql still has quite a few)

        - Be more strict on the group/user specifications; and output
          some diagnostics to the error log file if the admin does not
          specify a require (valid-)user with a group when the module
          is authorative.
