PSARC 2010/299 GNU/Linux/BSD compatibility functions

6960818 add get_nprocs(), getline(), strdupa(), strndup() to libc
6901783 strndup would be nice
6824404 libc should provide ffsl() & ffsll()
6793969 RFE: Add|stpcpy|to libc
6735446 Want a __progname symbol for BSD-style source compatibility
6421095 Solaris should provide strcasestr
6275498 Provide string compare functions wcscasecmp,wcsncasecmp in solaris like linux
