hurd: Reimplement libc locks using mach's gsync
* hurd/Makefile (routines): Add hurdlock. * hurd/Versions (GLIBC_PRIVATE): Added new entry to export the above interface. (HURD_CTHREADS_0.3): Remove __libc_getspecific. * hurd/hurdpid.c: Include <lowlevellock.h> (_S_msg_proc_newids): Use lll_wait to synchronize. * hurd/hurdsig.c: (reauth_proc): Use __mutex_lock and __mutex_unlock. * hurd/setauth.c: Include <hurdlock.h>, use integer for synchronization. * mach/Makefile (lock-headers): Remove machine-lock.h. * mach/lock-intern.h: Include <lowlevellock.h> instead of <machine-lock.h>. (__spin_lock_t): New type. (__SPIN_LOCK_INITIALIZER): New macro. (__spin_lock, __spin_unlock, __spin_try_lock, __spin_lock_locked, __mutex_init, __mutex_lock_solid, __mutex_unlock_solid, __mutex_lock, __mutex_unlock, __mutex_trylock): Use lll to implement locks. * mach/mutex-init.c: Include <lowlevellock.h> instead of <cthreads.h>. (__mutex_init): Initialize with lll. * manual/errno.texi (EOWNERDEAD, ENOTRECOVERABLE): New errno values. * sysdeps/mach/Makefile: Add libmachuser as dependencies for libs needing lll. * sysdeps/mach/hurd/bits/errno.h: Regenerate. * sysdeps/mach/hurd/cthreads.c (__libc_getspecific): Remove function. * sysdeps/mach/hurd/bits/libc-lock.h: Remove file. * sysdeps/mach/hurd/setpgid.c: Include <lowlevellock.h>. (__setpgid): Use lll for synchronization. * sysdeps/mach/hurd/setsid.c: Likewise with __setsid. * sysdeps/mach/bits/libc-lock.h: Include <tls.h> and <lowlevellock.h> instead of <cthreads.h>. (_IO_lock_inexpensive): New macro (__libc_lock_recursive_t, __rtld_lock_recursive_t): New structures. (__libc_lock_self0): New declaration. (__libc_lock_owner_self): New macro. (__libc_key_t): Remove type. (_LIBC_LOCK_INITIALIZER): New macro. (__libc_lock_define_initialized, __libc_lock_init, __libc_lock_fini, __libc_lock_fini_recursive, __rtld_lock_fini_recursive, __libc_lock_lock, __libc_lock_trylock, __libc_lock_unlock, __libc_lock_define_initialized_recursive, __rtld_lock_define_initialized_recursive, __libc_lock_init_recursive, __libc_lock_trylock_recursive, __libc_lock_lock_recursive, __libc_lock_unlock_recursive, __rtld_lock_initialize, __rtld_lock_trylock_recursive, __rtld_lock_lock_recursive, __rtld_lock_unlock_recursive __libc_once_define, __libc_mutex_unlock): Reimplement with lll. (__libc_lock_define_recursive, __rtld_lock_define_recursive, _LIBC_LOCK_RECURSIVE_INITIALIZER, _RTLD_LOCK_RECURSIVE_INITIALIZER): New macros. Include <libc-lockP.h> to reimplement libc_key* with pthread_key*. * hurd/hurdlock.c: New file. * hurd/hurdlock.h: New file. * mach/lowlevellock.h: New file
