Do not declare asctime_r and ctime_r for C2X
ISO C2X added the asctime_r, ctime_r, gmtime_r and localtime_r functions from POSIX. It's now removed asctime_r and ctime_r again, reflecting that they are marked obsolescent in POSIX; update glibc's time.h accordingly. The same change that removed those two functions from C2X also marked asctime and ctime as deprecated (reflecting how POSIX shows them as obsolescent), i.e. using the [[deprecated]] attribute in the prototypes shown in C2X. It's less clear if we should explicitly deprecate those functions like that in the glibc headers; this patch does nothing regarding such a deprecation (there's no normative requirement from C2X showing the functions as deprecated). Tested for x86_64 and x86.
