Samuel Thibault dc33bef307 hurd: Replace threadvars with TLS 
This gets rid of a lot of kludge and gets closer to other ports.

	* hurd/Makefile (headers): Remove threadvar.h.
	(inline-headers): Remove threadvar.h.
	* hurd/Versions (GLIBC_2.0: Remove __hurd_sigthread_stack_base,
	__hurd_sigthread_stack_end, __hurd_sigthread_variables,
	__hurd_threadvar_max, __hurd_errno_location.
	(HURD_CTHREADS_0.3): Add pthread_getattr_np, pthread_attr_getstack.
	* hurd/hurd/signal.h: Do not include <hurd/threadvar.h>.
	(_hurd_self_sigstate): Use THREAD_SELF to get _hurd_sigstate.
	(_HURD_SIGNAL_H_EXTERN_INLINE): Use THREAD_SELF to get _hurd_sigstate,
	unless TLS is not initialized yet, in which case we do not need a
	critical section yet anyway.
	* hurd/hurd/threadvar.h: Include <tls.h>, do not include
	<machine-sp.h>.
	(__hurd_sigthread_variables, __hurd_threadvar_max): Remove variables
	declarations.
	(__hurd_threadvar_index): Remove enum.
	(_HURD_THREADVAR_H_EXTERN_INLINE): Remove macro.
	(__hurd_threadvar_location_from_sp,__hurd_threadvar_location): Remove
	inlines.
	(__hurd_reply_port0): New variable declaration.
	(__hurd_local_reply_port): New macro.
	* hurd/hurdsig.c (__hurd_sigthread_variables): Remove variable.
	(interrupted_reply_port_location): Add thread_t parameter.  Use it
	with THREAD_TCB to access thread-local variables.
	(_hurdsig_abort_rpcs): Pass ss->thread to
	interrupted_reply_port_location.
	(_hurd_internal_post_signal): Likewise.
	(_hurdsig_init): Use presence of cthread_fork instead of
	__hurd_threadvar_stack_mask to start signal thread by hand.
	Remove signal thread threadvar initialization.
	* hurd/hurdstartup.c: Do not include <hurd/threadvar.h>
	* hurd/sigunwind.c: Include <hurd/threadvar.h>
	(_hurdsig_longjmp_from_handler): Use __hurd_local_reply_port instead
	of threadvar.
	* sysdeps/mach/hurd/Versions (libc.GLIBC_PRIVATE): Add
	__libc_lock_self0.
	(ld.GLIBC_2.0): Remove __hurd_sigthread_stack_base,
	__hurd_sigthread_stack_end, __hurd_sigthread_variables.
	(ld.GLIBC_PRIVATE): Add __libc_lock_self0.
	* sysdeps/mach/hurd/cthreads.c: Add __libc_lock_self0.
	* sysdeps/mach/hurd/dl-sysdep.c (errno, __hurd_sigthread_stack_base,
	__hurd_sigthread_stack_end, __hurd_sigthread_variables, threadvars,
	__hurd_threadvar_stack_offset, __hurd_threadvar_stack_mask): Do not
	define variables.
	* sysdeps/mach/hurd/errno-loc.c: Do not include <errno.h> and
	<hurd/threadvar.h>.
	[IS_IN(rtld)] (rtld_errno): New variable.
	[IS_IN(rtld)] (__errno_location): New weak function.
	[!IS_IN(rtld)]: Include "../../../csu/errno-loc.c".
	* sysdeps/mach/hurd/errno.c: Remove file.
	* sysdeps/mach/hurd/fork.c: Include <hurd/threadvar.h>
	(__fork): Remove THREADVAR_SPACE macro and its use.
	* sysdeps/mach/hurd/i386/init-first.c (__hurd_threadvar_max): Remove
	variable.
	(init): Do not initialize threadvar.
	* sysdeps/mach/hurd/i386/libc.abilist (__hurd_threadvar_max): Remove
	symbol.
	* sysdeps/mach/hurd/i386/sigreturn.c (__sigreturn): Use
	__hurd_local_reply_port instead of threadvar.
	* sysdeps/mach/hurd/i386/tls.h (tcbhead_t): Add reply_port and
	_hurd_sigstate fields.
	(HURD_DESC_TLS, __LIBC_NO_TLS, THREAD_TCB): New macro.
	* sysdeps/mach/hurd/i386/trampoline.c: Remove outdated comment.
	* sysdeps/mach/hurd/libc-lock.h: Do not include <hurd/threadvar.h>.
	(__libc_lock_owner_self): Use &__libc_lock_self0 and THREAD_SELF
	instead of threadvar.
	* sysdeps/mach/hurd/libc-tsd.h: Remove file.
	* sysdeps/mach/hurd/mig-reply.c (GETPORT, reply_port): Remove macros.
	(use_threadvar, global_reply_port): Remove variables.
	(__hurd_reply_port0): New variable.
	(__mig_get_reply_port): Use __hurd_local_reply_port and
	__hurd_reply_port0 instead of threadvar.
