* 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/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.
