Update.
* stdlib/stdlib.h (drand48_data): Make available only for
__USE_MISC. Rename elements to protect namespace. Change type
and position of a and init element.
* stdlib/drand48-iter.c: Don't handle unsigned short > 16 bit
differently. Adjust for drand48_data change. Don't compute a here,
it comes from drand48_data.
* stdlib/lcong48_r.c: Don't handle unsigned short > 16 bit
differently. Adjust for drand48_data change. Compute a here.
* stdlib/srand48_r.c: Likewise.
* stdlib/drand48.c: Adjust for drand48_data change.
* stdlib/lrand48.c: Likewise.
* stdlib/mrand48.c: Likewise.
* stdlib/seek48.c: Likewise.
* stdlib/drand48_r.c: Likewise.
* stdlib/lrand48_r.c: Likewise.
* stdlib/mrand48_r.c: Likewise.
* stdlib/seed48_r.c: Likewise. Don't handle unsigned short > 16 bit
differently.
* stdlib/erand48_r.c: Don't handle unsigned short > 16 bit differently.
* stdlib/jrand48_r.c: Likewise.
