This generic implementation already expects a getdents API which
is Linux specific. It also allows simplify it by assuming
_DIRENT_HAVE_D_RECLEN and _DIRENT_HAVE_D_OFF support.
The readdir are also expanded on each required implementation,
futher fixes and improvements will make parametrize the
implementation more complex.
Checked on x86_64-linux-gnu, i686-linux-gnu, and with a build
for all affected ABIs.
This patch consolidates Linux readdir{64}{_r} implementation on just
the default sysdeps/unix/sysv/linux/readdir{64}{_r}.c ones. The
default implementation handle the Linux requirements:
* readdir{_r} is only built for _DIRENT_MATCHES_DIRENT64 being 0.
* readdir64{_r} is always built and aliased to readdir{_r} for
ABI that define _DIRENT_MATCHES_DIRENT64.
* A compat symbol is added for readdir64{_r} for ABI that used to
export the old non-LFS version.
Checked on aarch64-linux-gnu, x86_64-linux-gnu, i686-linux-gnu,
sparcv9-linux-gnu, sparc64-linux-gnu, powerpc-linux-gnu, and
powerpc64le-linux-gnu.

is hidden with libc_hidden_proto and libc_hidden_def since the exported
