* libc/include/stdlib.h: Add declarations of rand48 functions and
their reentrant versions.
* libc/include/sys/reent.h: Move macros from rand48.h. Add
struct _rand48 for shared parameters of rand48 functions.
(struct _reent): Add a variable _r48 of struct _rand48.
(_REENT_INIT): Add _r48 initialization.
* libc/stdlib/Makefile.am (lib_a_SOURCES): Add rand48 functions.
(CHEWOUT_FILES): Add rand48.def.
* libc/stdlib/Makefile.am: Add dependencies for rand48 functions.
* libc/stdlib/Makefile.in: Regenerated.
* libc/stdlib/drand48.c (drand48, _drand48_r): Derived from the
NetBSD C library.
* libc/stdlib/erand48.c (erand48, _erand48_r): Ditto.
* libc/stdlib/jrand48.c (jrand48, _jrand48_r): Ditto.
* libc/stdlib/lcong48.c (lcong48, _lcong48_r): Ditto.
* libc/stdlib/lrand48.c (lrand48, _lrand48_r): Ditto.
* libc/stdlib/mrand48.c (mrand48, _mrand48_r): Ditto.
* libc/stdlib/nrand48.c (nrand48, _nrand48_r): Ditto.
* libc/stdlib/seed48.c (seed48, _seed48_r): Ditto.
* libc/stdlib/srand48.c (srand48, _srand48_r): Ditto.
* libc/stdlib/rand48.c (__dorand48): Ditto.
* libc/stdlib/rand48.h: Ditto, and modify declarations of global
parameters into macros referring them in the reentrant structure.
