The host decodes synchronously, so only the infinite timeout that
sceOpusDecDecode itself passes can be honoured. Other timeouts still
return the argument errors and then report the path as unimplemented,
because on the console the result depends on whether the AJM batch
finishes within the timeout.

Both modules route every decode export through one worker. Its checks
run in this order: state, packet, size, PCM pointer, capacity, then a
priority outside 20..100 (+0xA), then the state check (+1). Decode passes
priority 40.
The float exports decode 16-bit PCM into capacity / 4 * 2 bytes of the
caller's buffer and widen each sample in place, dividing positive
samples by 32767 and the rest by 32768. They return the float byte count.
The OpusDec *AndTimeout exports take a timeout for the AJM batch wait and
a pointer that receives the batch ID only when that wait fails. The host
decode is synchronous, so neither is used; the debt entry records this.

AnyPS5 resolves a title's imports by NID, so a title that imports a system
function no library provides fails to load with an unresolved import. The
PS5 3.20 export inventory lists 193 such exports across 37 PS5 system
libraries AnyPS5 implements but does not provide.
Declare them as throwing stubs so those titles load and reach their next
blocker. Each declaration calls NotImplemented_nid_no_patch and returns 0;
none of them implements the function. Declarations with a credible
prototype use it and cite the source with a pinned commit, and the rest
are declared without parameters, which resolves the import without making
an ABI claim. The technical-debt files record the limitation per library.
libSceMbus and libSceSystemService are left out because pull request #7821
declares them. libSceAgc is left out because its exports are versioned, so
the 3.20 NID names a different symbol from the one AnyPS5 ships.
libSceAvPlayer.native is left out because it compiles libSceAvPlayer's
Export.cpp.
Names and NIDs come from the PS5 3.20 export inventory at

Accept every creation rate listed by the public decoder research in
libSceOpusDec and libSceOpusCeltDec, resampling FFmpeg's 48 kHz output.

FFmpeg resamples narrowband SILK (TOC configurations 0-3) from 8 kHz and
holds back 24 samples of the first narrowband packet after the decoder
starts or after a packet of another bandwidth: a 20 ms packet decodes to
936 samples and the next wider packet to 984. sceOpusDecDecode required
exactly the packet's duration and threw, so ProsperoRadio aborted on a
narrowband Opus station.
The decoder now keeps FFmpeg's output in a queue and returns exactly the
packet's duration, as libopus does: the first narrowband packet starts
with 24 samples of silence and the held-back samples follow in the next
calls. The new test decodes three libopus 6 kb/s narrowband packets and
a wideband packet after them; it aborts on main.
