Subject: Allow direct access to the dirfd of a directory handle
X-Git-Tag: v2.12.0-rc1~573

Allow direct access to the dirfd of a directory handle

Serialization functions need access to the dirfd of a directory handle
in order to pass the fd and re-build the directory handle in
another process.

This function should not be used for other purposes. It is
also only available in the 'enable-dirfd' configuration, which
is assumed for the session daemon.
