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.

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.

__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/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.
