Y2038: provide kernel support indication
Introduce __ASSUME_KERNEL_Y2038_SUPPORT which means that
the underlying kernel *always* implements 64-bit-time Y2038-proof
syscalls.
If __ASSUME_KERNEL_Y2038_SUPPORT is not defined, glibc must
check dynamically whether the underlying kernel provides these
syscalls or not, and must fallback to 32-bit-time syscalls if
not.
Introduce function __y2038_get_kernel_support(), which returns
true if the underlying kernel supports 64-bit-time syscalls.
Also introduce function __y2038_set_kernel_support(), which
allows an implementation to notify glibc of the absence of
64-bit-time syscalls (ENOSYS) so that they are not needlessly
tried again.
