[PATCH] <string.h>: Make strchrnul, strcasestr, memmem available by default

[PATCH] <string.h>: Make strchrnul, strcasestr, memmem available by default

[Florian Weimer]

FreeBSD makes them available by default, too, so there does not seem
to be a reason to restrict these functions to _GNU_SOURCE.

Tested on x86_64-linux-gnu.

Thanks, finally pushed this after re-testing.
