Align seekdir and telldir API to POSIX definition.
* Makefile.in (NEW_FUNCTIONS): Remove seekdir and telldir mappings.
* dir.cc (telldir): Move functionality from telldir64 here. Use
long, rather than _off_t.
(telldir64): Just call telldir. Only keep for backward compatibility.
(seekdir): Move functionality from seekdir64 here. Use long, rather
than _off_t.
(seekdir64): Just call seekdir. Only keep for backward compatibility.
* fhandler.h: Throughout, change prototypes of seekdir and telldir
methods to use long, rather than _off64_t.
* fhandler_disk_file.cc: Change aforementioned methods accordingly.
* fhandler_netdrive.cc: Ditto.
* fhandler_registry.cc: Ditto.
* fhandler_virtual.cc: Ditto.
* include/sys/dirent.h (struct __DIR): Change __d_position from
_off_t to long to reflect API change.
(telldir): Change prototype to use long, rather than off_t.
(seekdir): Ditto.
