nptl: Rename lll_timedlock to lll_clocklock and add clockid parameter Rename lll_timedlock to lll_clocklock and add clockid parameter to indicate the clock that the abstime parameter should be measured against in preparation for adding pthread_mutex_clocklock. The name change mirrors the naming for the exposed pthread functions: timed => absolute timeout measured against CLOCK_REALTIME (or clock specified by attribute in the case of pthread_cond_timedwait.) clock => absolute timeout measured against clock specified in preceding parameter. * sysdeps/nptl/lowlevellock.h (lll_clocklock): Rename from lll_timedlock and add clockid parameter. (__lll_clocklock): Rename from __lll_timedlock and add clockid parameter. * sysdeps/unix/sysv/linux/sparc/lowlevellock.h (lll_clocklock): Likewise. * nptl/lll_timedlock_wait.c (__lll_clocklock_wait): Rename from __lll_timedlock_wait and add clockid parameter. Use __clock_gettime rather than __gettimeofday so that clockid can be used. This means that conversion from struct timeval is no longer required. * sysdeps/sparc/sparc32/lowlevellock.c (lll_clocklock_wait): Likewise. * sysdeps/sparc/sparc32/lll_timedlock_wait.c: Update comment to refer to __lll_clocklock_wait rather than __lll_timedlock_wait. * nptl/pthread_mutex_timedlock.c (lll_clocklock_elision): Rename from lll_timedlock_elision, add clockid parameter and use meaningful names for other parameters.
