daedalus-v4l2{,-dkms}: f0d4186 -> 79256dc — H.264 B-frame reorder + menu ctrls

Browse Source 
Lock-step bump of both packages to daedalus-v4l2#7 + #4.  PROTO_VERSION
bumps 0 → 1 at the daemon ↔ kernel chardev wire: REQ_DECODE adds
__u64 src_pts (the OUTPUT vb2 timestamp); RESP_FRAME adds __u32 flags
(HAS_PIXELS / SRC_CONSUMED) + __u64 output_src_pts (= frame->pts on
drain).  Both .debs must be installed atomically or the chardev
handshake rejects the version mismatch.

  * daedalus-v4l2: daemon's send_packet → receive_frame loop now
    stamps pkt->pts = req->src_pts and looks up the cookie for each
    drained frame via frame->pts.  chardev_client emits multiple
    RESP_FRAME messages per REQ_DECODE when libavcodec's display-
    order DPB releases an earlier frame on receipt of a later
    bitstream — fixes the "2 1 4 3 6 5" pair-swap on H.264 streams
    with B-frames.

  * daedalus-v4l2-dkms: kernel device_run mirrors src_buf timestamp
    into REQ_DECODE.src_pts.  Completion path splits HAS_PIXELS /
    SRC_CONSUMED: src is released as soon as send_packet succeeds
    (so the m2m scheduler moves on), dst stays parked until the
    matching frame is drained later.  TIMESTAMP_COPY's auto src→dst
    pairing no longer applies once lifecycles decouple — dst is
    stamped explicitly from inflight->src_pts at HAS_PIXELS time.

  * daedalus-v4l2-dkms also carries forward the -2 multi-kernel
    postinst fix (#64) from the prior PKGREL.  PKGREL resets to 1 on
    the new upstream pin.

The daedalus-v4l2#4 H.264 DECODE_MODE + START_CODE menu controls (a
cosmetic warning fix that PR landed alongside #7) is also subsumed —
"Unable to set control(s) error_idx=2/2" no longer fires.
