2000-12-11 Joel Sherrill <joel@OARcorp.com> * Merge RTEMS specific .h files into main libc/include. * libc/sys/rtems/include/signal.h: Removed. * libc/sys/rtems/include/time.h: Removed. * libc/sys/rtems/sys/features.h: Removed. * libc/sys/rtems/sys/sched.h: Removed. * libc/sys/rtems/sys/siginfo.h: Removed. * libc/sys/rtems/sys/signal.h: Removed. * libc/sys/rtems/sys/time.h: Removed. * libc/sys/rtems/sys/times.h: Removed. definitions for time_t and clock_t since these are no longer in time.h. * libc/include/pthread.h: New file. * libc/include/sys/sched.h: New file. * libc/include/sys/features.h: New file. * libc/include/time.h: Removed duplicate definition of clock_t and time_t, get them from <sys/types.h> instead. Add prototypes for POSIX clock and timer functionality. * libc/sys/linux/sys/types.h: Changed to include * libc/include/machine/types.h: Add _CLOCKID_T_ and _TIMER_T_. * libc/include/sys/signal.h: Add more complete set of POSIX signal functionality including real-time and threaded signals. * libc/include/sys/types.h: Add clock_t, time_t, struct timespec, and struct itimerspec. Centralizing these makes things cleaner. RTEMS uses 64-bit dev_t. Added numerous primitive definitions for pthreads including macros, pthread_attr_t, pthread_mutexattr_t, pthread_condattr_t, pthread_key_t, pthread_once_t, and pthread_t. * libc/include/sys/unistd.h: Added getlogin_r() prototype. If RTEMS follow POSIX on read(), write() and sbrk() prototype. Feature flags removed and moved to new file <sys/features.h>. Full set of POSIX sysconf() constants
