Fix qsort_r namespace (bug 17571).
qsort_r is defined in the same file as qsort, but is not an ISO C function, so should be a weak alias for __qsort_r. The uses in getaddrinfo should also call __qsort_r, since getaddrinfo is a POSIX function and qsort_r isn't. This patch implements this. Because nscd uses the getaddrinfo sources outside libc, as do the tst-rfc3484 tests, a #define of __qsort_r to qsort_r is added there alongside the similar defines for other libc-internal symbols used in getaddrinfo. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). [BZ #17571] * stdlib/msort.c (qsort_r): Rename to __qsort_r and define as weak alias of __qsort_r. (qsort): Call __qsort_r instead of qsort_r. * include/stdlib.h (qsort_r): Do not call libc_hidden_proto. (__qsort_r): Declare. Call libc_hidden_proto. * sysdeps/posix/getaddrinfo.c (getaddrinfo): Call __qsort_r instead of qsort_r. * nscd/gai.c (__qsort_r): Define to qsort_r. * posix/tst-rfc3484.c (__qsort_r): Likewise. * posix/tst-rfc3484-2.c (__qsort_r): Likewise. * posix/tst-rfc3484-3.c (__qsort_r): Likewise.
