* [agc] WAIT_REG_MEM suspend/resume, draw packet fixes, new HLE exports, debug cleanup
Rebased onto upstream 79a7437 (par274/sharpemu, rewritten history).
- GpuWaitRegistry: DCBs suspended on unsatisfied WAIT_REG_MEM are re-polled
against guest memory on every submit; fixed 64-bit and standard packet parse
offsets, apply the mask, treat PM4 compare function 0 as "always".
- TryReadSubmittedDrawCount: accept the 5-dword ItDrawIndex2 form emitted by
DcbDrawIndex (count at +4); menu draws were silently discarded before.
- sceAgcDriverSubmitMultiDcbs: reversed ABI (rdi=address array, rsi=dword
sizes, rdx=count).
- VideoOut: vblank events, sceVideoOutGetFlipStatus, buffers registered via
sceVideoOutRegisterBuffers are valid flip targets.
- New HLE: libc stdio (fopen/fread/fseek/ftell/fclose/fgets), Dinkumware
_Getpctype ctype table, NpTrophy2 stubs, AMPR PAK sequential-read tracker,
MsgDialog lifecycle, NGS2 alt NIDs + dummy vtable for handle objects,
guarded memset intrinsic, abort()/strcasecmp null-arg recovery.
- Removed investigation-only code (INT3 breakpoints, qfont/mcpp dumps,
error-candidate printf traces, unconditional debug logs).
First rendered frame: Quake (PPSA01880) presents a 1920x1080 guest frame.
* Implemented a guarded native intrinsic (rep movsb) in DirectExecutionBackend to bypass HLE dispatch overhead, while preserving memory safety checks.
