final module ID with _dl_next_tls_modid.
* include/link.h (struct link_map): Add l_tls_previmage and
l_tls_align.
* eld/dl-support.c: Define _dl_tls_max_dtv_idx and _dl_tls_dtv_gaps.
* sysdeps/i386/elf/Versions: New file.
* sysdeps/generic/dl-tls.c: New file.
* sysdeps/generic/dl-tls.h: New file.
* sysdeps/i386/dl-tls.h: New file.
attribute((packed)) to counter stupid people misusing gcc options.
* elf/rtld.c (_dl_start): Fill TLS values in link map for rtld.
* include/link.h (struct link_map): Add various members for TLS
information.
* sysdeps/generic/ldsodefs.h (struct rtld_global): Remove
_rtld_tlsoffset, add _dl_initimage_list.
* sysdeps/i386/dl-lookupcfg.h: New file.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Implement missing
TLS relocation. When using TLS we now use RESOLVE_MAP.
(elf_machine_rela): Use RESOLVE_MAP instead of RESOLVE_MAP if TLS
is used.
* sysdeps/generic/dl-cache.c (_dl_cache_libcmp): Mark as possibly
unused.
* elf/rtld.c (_dl_start_final): Allocate TLS and initialize
thread-pointer as soon as possible.
* sysdeps/generic/ldsodefs.h: Include <tls.h>. Define first TLS
elements in rtld_global.
* sysdeps/generic/tls.h: New file.
* elf/Makefile (distribute): Add tls.h.
* sysdeps/i386/dl-machine.h (elf_machine_rel): Add support for TLS
relocations. Not complete yet.
* resolv/resolv.h: Allow user to define __need_res_state and only
define __res_start structure then.
* include/resolv.h: Only declare functions if _RESOLV_H_ is defined.
