Feature test macros overhaul: string.h

Browse Source 
Throughout, remove __STRICT_ANSI__ and use the proper internal macros.

bcmp, bcopy, bzero, index, and rindex were in POSIX prior to 2008.

memrchr is GNU.

strdup and strndup are POSIX.1-2008.

The int-returning form of strerror_r is POSIX.1-2001.
