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

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.

daedalus-v4l2-dkms (0.1.0+r28+g79256dc-1) bookworm trixie; urgency=medium
* Bump to 79256dc — H.264 B-frame display reorder fix (closes
daedalus-v4l2#6). libavcodec's H.264 decoder reorders output to
display order before returning from avcodec_receive_frame; the
daemon was binding each REQ_DECODE's pixels to the cookie of the
bitstream that triggered the receive_frame call, not the cookie
of the bitstream that actually produced the picture. For B-frame
sequences this paired cookie N's CAPTURE buffer with cookie N-2's
pixels and silently lost intermediate frames — visible as
"2 1 4 3 6 5" frame pairing in mpv / Firefox on Pi CM5.
* Wire-protocol bump (DAEDALUS_PROTO_VERSION 0 → 1): REQ_DECODE
gains __u64 src_pts; RESP_FRAME gains __u32 flags +
__u64 output_src_pts. Kernel + daemon must install atomically
(this package + daedalus-v4l2 0.1.0+r28+g79256dc).
* Carries forward the #64 multi-kernel postinst fix from -2:
autoinstall for every /lib/modules/*/build that resolves to real
headers, not just $(uname -r).
* Closes #64.

* Bump to 79256dc — H.264 B-frame display reorder fix (closes
daedalus-v4l2#6 + #4 menu controls). Daemon side: the
avcodec_send_packet → receive_frame loop now stamps pkt->pts =
req->src_pts so libavcodec's display-ordered frame->pts identifies
which OUTPUT bitstream's pixels each drained frame belongs to.
chardev_client maintains a (src_pts → cookie) lookup table so the
daemon can ship pixels to the cookie of the *originating*
bitstream, not the cookie of whatever REQ triggered the
receive_frame call. Multiple RESP_FRAME messages per REQ_DECODE
are now possible (one for the just-consumed src, one or more for
drained pixels).
* Wire-protocol bump (DAEDALUS_PROTO_VERSION 0 → 1): REQ_DECODE
gains __u64 src_pts; RESP_FRAME gains __u32 flags +
__u64 output_src_pts. Daemon + kernel must install atomically
(this package + daedalus-v4l2-dkms 0.1.0+r28+g79256dc).
* Also subsumes 79256dc's predecessor 7ff2d89 — H.264 DECODE_MODE +
START_CODE menu-control registration that retires the
"Unable to set control(s) error_idx=2/2" warning libva-v4l2-
request emitted on every context init.
