    [BZ #16046] Static dlopen correction fallout fixes.

    Fixes to address issues from BZ #15022 resolution, as follows:

    * TLS updates to csu/libc-tls.c -- we now have a proper main map, so
      there's no longer a need to create a separate fake one to keep TLS
      structures,

    * random updates to elf/dl-close.c -- LM_ID_BASE is now a valid name
      space ID for static executables as well, so assert that we don't
      unload the main map. Similarly dl_nns isn't supposed to be 0 for
      static executables anymore,

    * actual BZ #16046 fix to elf/dl-iteratephdr.c -- the dl_iterate_phdr
      special function for static executables isn't needed anymore, provided
      that l_phdr and l_phnum members of the main map have been properly
      initialized (done in _dl_non_dynamic_init in elf/dl-support.c now),

    * ld.so.cache loader update to elf/dl-load.c --
      GL(dl_ns)[LM_ID_BASE]._ns_loaded is now always initialized in static
      executables so can become the fallback loader map to check for
      DF_1_NODEFLIB, provided that the l_flags_1 member of the main map has
      been properly initialized (done in elf/dl-support.c now); this also
      ensures previous semantics elsewhere in elf/dl-load.c,

    * matching updates to elf/dl-support.c -- to complement the two fixes
      above.
