libva-v4l2-request-fourier: bump pin to c454618 (#15 transparent resize)

Bumps both Arch PKGBUILD and Debian build-deb.sh pins to PR #16 —
codec_store_buffer + request_pool_resize transparent OUTPUT-pool grow
on a mid-session resolution upshift overrun.  Picks up the frame-
survival path that supersedes #13's drop-and-recreate fallback.

Dual-pin per feedback_marfrit_packages_dual_pin so both Arch and
Debian repos see check-already-published.sh report a new version.

@@ -18,27 +18,30 @@ This patch adds a sibling init path, `InitV4L2RequestDecoder`, that:
   * looks up the codec via two complementary mechanisms libavcodec
     uses for v4l2_request:
       - **named codec** (`h264_v4l2request`, `vp8_v4l2request`, etc.):
-        the legacy AVCodec-per-hwaccel registration. ALARM, Debian,
-        and most distros building with --enable-v4l2-request expose
-        this (avcodec_find_decoder_by_name lookup).
-      - **generic codec + AV_HWDEVICE_TYPE_DRM** in `hw_configs`:
-        the modern hwaccel registration on some upstream-only ffmpeg
-        builds.
+        the legacy AVCodec-per-hwaccel registration.
+      - **generic codec + hw_configs walk**: the modern hwaccel
+        registration. Accepts EITHER AV_HWDEVICE_TYPE_DRM (legacy
+        ffmpeg-v4l2-request-fork output prior to FFmpeg 7.1) OR
+        AV_HWDEVICE_TYPE_V4L2REQUEST (FFmpeg 7.1+ dedicated enum,
+        value 13 on Kwiboo's no-AMF tree, 14 on upstream-AMF tree).
+        Mozilla's bundled libavutil headers may not have the V4L2REQUEST
+        enumerator, so the test is on the integer value via `(int)cast`.
     Probes named-codec first (explicit, portable) and falls back to
-    walking the generic codec's `hw_configs` for the DRM device type;
-  * creates an `AV_HWDEVICE_TYPE_DRM` hwdevice context bound to
-    `/dev/dri/renderD128` via the new `av_hwdevice_ctx_create` wrapper
-    (patch 2/4) and attaches it to the codec context;
+    walking the generic codec's `hw_configs` for either device type;
+  * creates an hwdevice context bound to `/dev/dri/renderD128`. Uses
+    integer 13 (V4L2REQUEST as defined by Kwiboo's v4l2-request-n7.1.3
+    tree, what our libavcodec61-fourier emits) cast to enum
+    AVHWDeviceType for the av_hwdevice_ctx_create call;
   * reuses the existing `ChooseV4L2PixelFormat` get-format callback
     (already returns `AV_PIX_FMT_DRM_PRIME`) and the existing
     `apply_cropping = 0` constraint.
 
 `InitV4L2RequestDecoder` is invoked **before** `InitV4L2Decoder` in
 `InitHWDecoderIfAllowed`. On Rockchip mainline it succeeds via either

+
+  * 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.

+  * postinst: autoinstall for every installed kernel with headers, not
+    just the running one.  Previously `dkms autoinstall $NAME/$VERSION`
+    built only against `$(uname -r)`, so installing the package on
+    kernel A and then rebooting into a separately-installed kernel B
+    left /lib/modules/B/updates/dkms/ empty — /dev/daedalus-v4l2 absent,
+    daedalus daemon nothing to talk to, browser/VAAPI silently falling
+    back to software with no obvious diagnostic.  Now we enumerate every
+    /lib/modules/*/build that resolves to a real directory and run
+    `dkms autoinstall -k <kver>` for each, reporting per-kernel failure
+    only when headers are missing.  Closes #64.

+    bitstream, not the cookie of whatever REQ triggered the
+    receive_frame call.  Multiple RESP_FRAME messages per REQ_DECODE
