[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.
