* tst-context.c: #define IS_IN_libpthread around #include <tls.h>
before other headers, so FLOATING_STACKS is not defined wrongly.
* sysdeps/i386/tls.h [!IS_IN_libpthread]: Enable TLS support
even if [! FLOATING_STACKS].
(TLS_DO_MODIFY_LDT_KERNEL_CHECK): New macro.
If not under [__ASSUME_LDT_WORKS > 0], then do a runtime check of
dl_osversion >= 2.3.99 and fatal if not.
(TLS_DO_MODIFY_LDT): Use it.

* pthreadP.h (__stack_user, __nptl_create_event, __nptl_death_event):
Declare using hidden_proto instead of attribute_hidden, so there are
non-.hidden static symbols for gdb to find.
(__pthread_keys): Likewise.
* events.c (__nptl_create_event, __nptl_death_event): Add hidden_def.
* allocatestack.c (__stack_user): Likewise.
* pthread_create.c (__pthread_keys): Likewise.
(__nptl_threads_events, __nptl_last_event): Make these static instead
of hidden.
* pthread_key_create.c (__pthread_pthread_keys_max,
__pthread_pthread_key_2ndlevel_size): Renamed from __linuxthreads_*.
