claude-noether c5fbc5bf04 iter2 step2: GLib/GStreamer compat shim, build succeeds 
Vendored gsth265parser + nalutils + gstbitreader + gstbytereader (the
Step 1 commit) compile cleanly against libc + libv4l2 only after
adding 1 compat translation unit + 5 stub headers, no edits to the
vendored .c/.h files themselves.

src/h265_parser/gst_compat.{h,c} — new files (MIT, original work):
  - GLib type aliases (gboolean, gchar, gint*, guint*, gsize, gpointer)
  - Memory helpers (g_malloc/g_free as #define free, g_memdup2 inline)
  - Asserts as no-op + parser-return-code-propagation
  - All GST_DEBUG/INFO/WARNING/ERROR/LOG/FIXME as no-ops (the parser
    is heavy on debug logging; we compile it all out)
  - GArray implementation (~100 LOC, just enough for gsth265parser.c's
    24 call sites)
  - GList full struct with .data/.next/.prev so callers compile;
    list-manipulation functions abort() — dead code paths only
  - Byte-order read/write macros (GST_READ_UINT8/16/24/32/64_LE/BE,
    GST_WRITE_UINT8/16/24/32_BE) — aarch64 LE inlines
  - g_once_init_enter/leave as simple gate
  - G_MAXUINT*, G_MAXINT*, G_MINxxx, G_GNUC_* attribute macros, etc.
  - Opaque GstBuffer/GstMemory/GstMapInfo + abort-stub functions for
    the encoder-side SEI-insertion paths the libva backend never invokes
  - gst_util_ceil_log2 real impl (used by slice-header parser; dead
    for our SPS-only call path but cheaper to implement than stub)

src/h265_parser/gst/{gst.h,base/base-prelude.h,base/gstbitwriter.h,
codecparsers/codecparsers-prelude.h,glib-compat-private.h} — 5 new
stub headers (MIT). All include gst_compat.h. gstbitwriter.h adds
abort-stub functions for the bit-writer API (used by nalutils.c's NAL
emulation-prevention encoder path — dead code for the parse-only
libva backend).

src/meson.build — added the 5 new .c source files and 10 new .h
headers; added include_directories('h265_parser') to the include path
so the vendored files' '#include <gst/base/...>' style references
resolve to the stub headers + actual vendored files in the local
tree.

Build verified: ninja -C build produces v4l2_request_drv_video.so
(682 KB, up from 485 KB pre-vendor — the +200 KB is the vendored
parser code). nm shows gst_h265_parse_sps, gst_h265_parse_sps_ext,
gst_h265_parser_identify_nalu, and the other functions we need for
Step 4 are present in the binary.

Two #warning messages from gsth265parser.h about API stability are
upstream-intentional and harmless ('The H.265 parsing library is
unstable API and may change in future').

This commit completes Step 2 of ampere-kernel-decoders iter2 Phase 6.
Backend remains functionally identical to pre-iter2 — the new code
compiles + links but is not yet called from h265_set_controls (that's
Step 4). Existing 5 codecs continue to work as before.
