* stdlib/stdlib.h: Define __compar_d_fn_t. Declare qsort_r.

Browse Source 
* include/stdlib.h: Add hidden_proto for qsort_t and adjust protoype
	for _quicksort.
	* stdlib/msort.c (qsort): Now a wrapper around qsort_r.
	(qsort_r): Renamed from qsort.  Take additional parameter and pass it
	on as third parameter to compare function and _quicksort.
	* stdlib/qsort.c (_quicksort): Take additional parameter and pass on
	to the compare function.
	* stdlib/Versions [libc] (GLIBC_2.8): Add qsort_r.
	* Versions.def: Add GLIBC_2.8 for libc.
