    linux: Use getdents64 on readdir64 compat implementation

    It uses a similar strategy from the non-LFS readdir that also
    uses getdents64 internally and reserves some space on the allocated
    internal DIR buffer to be used as a temporary buffer. The kernel
    obtained dirent64 data are copied to the temporary buffer for each
    readdir compat call.

    It allows to remove __old_getdents64.

    Checked on i686-linux-gnu.

    linux: Set internal DIR filepos as off64_t [BZ #23960, BZ #24050]

    It allows to obtain the expected entry offset on telldir and set
    it correctly on seekdir on platforms where long int is smaller
    than off64_t.

    On such cases telldir will mantain an internal list that maps the
    DIR object off64_t offsets to the returned long int (the function
    return value).  The seekdir will then set the correct offset from
    the internal list using the telldir as the list key.

    It also removes the overflow check on readdir and the returned value
    will be truncated by the non-LFS off_t size.  As Joseph has noted
    in BZ #23960 comment #22, d_off is an opaque value and since
    telldir/seekdir works regardless of the returned dirent d_off value.

    Finally it removed the requirement to check for overflow values on
    telldir (BZ #24050).

    Checked on i686-linux-gnu and x86_64-linux-gnu.

    linux: Use getdents64 on non-LFS readdir

    It reserves some space on the allocated internal buffer to be
    used as a the returned dirent struct.  The kernel obtained dirent64
    struct are copied to the temporary buffer on each readdir call.

    The overflow test is moved once the dirent64 entry is copied
    to the temporary buffer, and a subsequent readdir will obtain the
    next entry.  The idea is an overflow fails to return the entry on
    readdir, but a next readdir might still obtain the next entry.
    (for filesystem that does not have the concept of sequential d_off,
    such as ext4).

    Checked on x86_64-linux-gnu and i686-linux-gnu.

    linux: Simplify opendir buffer allocation

    THe fallback allocation is removed, so the possible size constraint
    should be analized just once; __alloc_dir assumes that 'statp'
    argument is non-null, and the max_buffer_size move to close its
    used.

    Checked on x86_64-linux-gnu and i686-linux-gnu.

    linux: Move posix dir implementations to Linux

    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 and i686-linux-gnu.
