First stage of support for Extended API set 2. Most of the think is
unimplemented, except enough of linkat(2) to hardlink to a symlink.
Everything new in headers is guarded #ifdef _INCOMPLETE_XOPEN_C063 since
some software (e.g.: xcvs in our own tree) will assume they can use openat(2)
when AT_FDCWD is defined. _INCOMPLETE_XOPEN_C063 will go away once support
will be completed.
regen
improve comment about AT_* defines: they are not only used by linkat(2)
Add macros to hide OpenGroup extened API set 2 from GNU configure. This
is a temporary  workaround until the implementation is completed.
