[PATCH v2] <stdio.h>: Make fopencookie, vasprintf, asprintf available by default

[PATCH v2] <stdio.h>: Make fopencookie, vasprintf, asprintf available by default

[Florian Weimer via Libc-alpha]

FreeBSD makes these functions available by default, so we should
not treat them as GNU-specific and restrict them to _GNU_SOURCE.

v2: Do not include fcloseall because it's broken.
