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