* exceptions.cc (set_signal_mask): Redefine to not pass by address. Report 

calculated mask in debugging output.
* sigproc.h (set_signal_mask): Reflect above change in declaration.
* path.cc (mount_item::build_win32): Take path apart before feeding it to
fnmunge.  Throughout, change use of _reent_winsup()-> to _my_tls.locals.
instead.  Throughout, remove obsolete MT_SAFE/_CYG_THREAD_FAILSAFE
considerations.  Througout, add cygtls.h include.
* Makefile.in (DLL_OFILES): Add cygtls.o.  Add some more objects to the
-fomit-frame-pointer list.
* acconfig.h: Remove obsolete settings.
* config.h.in: Ditto.
* bsdlib.cc: Add cygtls.h include.
* configure.in: Remove --enable-extra-threadsafe-checking.
* configure: Regenerate.
* cygtls.h (_local_storage): New struct renamed from _winsup_t (sic).
(_threadinfo:local_clib): Add new field.
(_threadinfo::locals): Ditto.
(_threadinfo::init_thread): Accept second _reent * argument.
(_threadinfo::call): Define as regparm.
(CYGTLS_PADSIZE): Remove unnecessary slop.
(_getreent): Define as a macro.
* thread.h: Remove _CYG_THREAD_FAILSAFE and MT_SAFE stuff.
(_winsup_t): Move to cygtls.h.
(ResourceLocks::ResourceLocks): Eliminate empty constructor.
(MTinterface::reents): Eliminate.
(MTinterface::thread_self_key): Eliminate.
(MTinterface::MTinterface): Eliminate.
* dcrt0.cc: Include stdio.h for _impure_ptr initialization.
(do_global_ctors): Remove run_ctors_p (sic) considerations.  Don't call atexit
here.
(__main): Initialize destructors for user here.
(dll_crt0_1): Accept a dummy argument.  Don't call init_thread here.  Don't set
_impure_ptr here.  Call do_global_ctors after more things have been
initialized.
(_dll_crt0): Define zeros buffer as max of needed size of CYGTLS_PADSIZE so
that it can be used for two purposes while minimizing stack usage.  Initialize
_impure_ptr specifically, for speed.  Call dll_crt0_1 with buffer argument.
(cygwin_dll_init): Call dll_crt0_1 with dummy argument.
* dtable.cc (dtable::find_unused_handle): Remove call to AssertResourceOwner.
* exceptions.cc: Move _threadinfo stuff to new file.
* cygtls.cc: New file.
* gentls_offsets: Accommodate increasing complexity of cygtls.h.

(AssertResourceOwner): Delete.
(MTinterface::Init): Remove setting of _clib and _winsup, with all that
entails.
(MTinterface::fixup_after_fork): Ditto.
(pthread::thread_init_wrapper): Ditto.  Also remove call to
set_tls_self_pointer.
(pthread::set_tls_self_pointer): Eliminate.
(pthread::get_tls_self_pointer): Just return _my_tls.tid;
