* elf/elf.h (AT_GID): Fix typo: Read -> Real. * misc/efgvt_r.c: New file. Reentrant version of [efg]cvt functions. * misc/efgcvt.c: Rewrite to use reentrant functions. * misc/hsearch_r.c: New file. Reentrant version of functions from hsearch family. * misc/hsearch.c, misc/tsearch.c: New files. * misc/Makefile (routines): Add efgcvt_r, hsearch_r, hsearch, tsearch. * posix/unistd.h (ttyname_r): Add prototype for new function. * stdlib/drand48_r.c, stdlib/erand48_r.c, stdlib/jrand48_r.c, stdlib/lrand48_r.c, stdlib/mrand48_r.c, stdlib/nrand48_r.c, stdlib/seed48_r.c, stdlib/srand48_r.c, stdlib/lcong48_r.c, stdlib/drand48-iter.c: New files implementing reentrant versions of functions from drand48 family. * stdlib/seed48.c, stdlib/drand48.c, stdlib/erand48.c, stdlib/jrand48.c, stdlib/lrand48.c, stdlib/mrand48.c, stdlib/nrand48.c, stdlib/srand48.c, stdlib/lcong48.c: Rewrite to use reentrant versions. * stdlib/a64l.c, stdlib/l64a.c: New files. Implement a64l() and l64a() functions from SysV library. * stdlib/Makefile (routines): Add drand48_r, erand48_r, lrand48_r, nrand48_r, mrand48_r, jrand48_r, srand48_r, seed48_r, lcong48_r, drand48-iter, a64l, l64a. * stdlib/stdlib.h: Declare them. * stdlib/random_r.c: New file. Reentrant version of functions from random family. * stdlib/stdlib.h: Declare them. * stdlib/random.c: Rewrite to use reentrant functions. * string/strerror_r.c: New file. Reentrant version. * string/strerror.c: Change for new _strerror_internal form. * string/Makefile (routines): Add strerror_r. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Set default value of user_entry to `_start'. Close AT_ENTRY case with `break'. * sysdeps/generic/strstr.c: New and much faster implementation by Stephen R. van den Berg. * sysdeps/generic/_strerror.c: _strerror_internal now takes three argument and has and explicit buffer length. * sysdeps/mach/_strerror.c: Change for new interface with three arguments. * stdio/perror.c, stdio/vfprintf.c: Callers changed. * sysdeps/mach/hurd/ttyname_r.c: New file. Reentrant version. * sysdeps/posix/ttyname_r.c: New file. Reentrant version. * sysdeps/stub/ttyname_r: New file. Define as dummy function. * sysdeps/posix/utimes.c: Include <utime.h> for prototype. (utimes): First parameter to utime must be file, not path. * sysdeps/posix/sysconf.c (__sysconf): Test for CLK_TCK in case _SC_CLK_TCK and return it when available. Test for STREAM_MAX in case _SC_STREAM_MAX and return it when available. Add case for _SC_2_LOCALEDEF which is now available. * posix/sys/types.h [__USE_SVID] (key_t): New type. * sysvipc/Makefile, sysvipc/ftok.c, sysvipc/sys/ipc.h, sysvipc/sys/msg.h, sysvipc/sys/sem.h, sysvipc/sys/shm.h, sysdeps/stub/sys/msq_buf.h, sysdeps/stub/sys/sem_buf.h, sysdeps/stub/sys/shm_buf.h, sysdeps/stub/sys/ipc_buf.h, sysdeps/stub/semctl.c, sysdeps/stub/semget.c, sysdeps/stub/semop.c, sysdeps/stub/shmat.c, sysdeps/stub/shmctl.c, sysdeps/stub/shmdt.c, sysdeps/stub/shmget.c, sysdeps/stub/msgctl.c, sysdeps/stub/msgget.c, sysdeps/stub/msgrcv.c, sysdeps/stub/msgsnd.c: New files. Add implementation of System V IPC.
