* 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.
