How to keep lldb and gdb from stopping on the faults the handler is meant
to catch, and the crash_*.prx tests as a quick check that it works.

Apple platforms now use the same SIGSEGV/SIGBUS handler as Linux instead of
a Mach exception port. The Mach port was only set on the installing thread,
which is the loader thread, not the one running JIT code. ARM64 had no
context definition at all.
Also pass the thread state (not the mcontext) to the handler, accept SIGBUS
fault codes, and fix restoring a disabled altstack on Darwin.

An interpreter state always claimed an uneaten VFPU prefix, which made a
JIT loading it run in unknown-prefix mode for the rest of the session.

Drop an ISO handle whose file isn't in the loaded image instead of keeping
a null file, and don't reopen a directory file with exclusive create.

Missing sections (videocodec, audiocodec, aac, mp3) and old-version
branches (impose, io, umd, gps, mic, display, font) left the session
before the load in place.

sceMpeg's AVC resource flag, whether the VSH is running, sceReg's handle
counter, sceNet's pending apctl events and product code block, and the
save dialog's copy of the original request (without which the first
Update after a load reloaded the request and lost its results).

__DmacDoState and __UsbCamDoState existed but weren't in the module list,
so the memcpy deadline and camera state carried over from before a load.
The NpDrm licensee key wasn't saved or reset at all, so EDATA opened after
a load in a fresh session couldn't be decrypted.

Without saved flags, those states were resolved against today's defaults,
and everything graduated since (sceMpeg, sceFont, the leaf libraries) ended
up on unresolved stubs.

The first one got n-1, which is the state's last event, so that one moved
to a new id while its queued occurrences fired the newcomer. n-1 dates
from before RestoreRegisterEvent could fall back when out of range. Also
recompute a debugger run-until deadline against the loaded clock.

gpu/clut/offset and gpu/commands/material take over 1s each in a Debug
build, and every so often pushed past the 5s limit mid-run, which reads
as a failure with truncated output.

Same as the exit callback: states from before them numbered the action
types without them, so the boot-time ids can belong to other types.
Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
A state from before the event kept its boot-time id, which Atrac restores
first, so the event the state had under that id moved to a new one while
its queued occurrences kept firing AtracOutput. In Outrun 2006 that was
the vblank, and the game waited for it forever.

MP3 emulation already went through FFmpeg, leaving MiniMp3Audio dead.
The one live user was loading MP3 UI sound effects (custom achievement
sounds), which now splits the file into frames and decodes them with
the FFmpeg MP3 decoder.

gpu/rendertarget/copy no longer prints a million pixels one at a time,
and runs in 0.17s under the interpreter rather than ~4.5s.

Neither is serialized, and both went stale on load. The ME busy time was
measured against the pre-load clock, so loading an earlier state made the
next SAS/codec job wait until the old time came around, freezing the game.

The write pass stores memory with the JIT's emuhacks cleared, but the
verify pass compared against memory that still had them, so it would
report a mismatch under a JIT. Only EMULATOR_DEVCTL__VERIFY_STATE runs it,
and nothing currently does. It also counted as a save in the generation.

Some DoState code meant for after a load ran on every save:
- scePower reset the bus frequency a game set (and with a locked CPU
speed, applied the current setting to the clock).
- sceDisplay reset the lag sync baseline, and could schedule lag sync in
the measuring pass only, which failed the save.
- GPUState dirtied the texture, sceUmd notified the UI, and sceMpeg
dropped a pending ringbuffer fix-up for an old state.

CoreTiming::DoState replaced every event's callback with the anti-crash
one in every mode, relying on each module's restore to put it back. A save
that failed partway never got to those, and left the running game with
events that break into the debugger. The missing-section fallbacks then
also ran on the save: cheats and the mic re-registered events into the
wrong slots, and achievements reset the runtime.

SetError overwrote the first bad section with whichever section a later
error came from, and an error before any section read an uninitialized
curTitle_.

DoMap and DoSet cleared them, but only once the count had been read. A
state truncated right there left the deleted pointers in place, to be
freed again when the failed load reset the game.

The list belongs to the sceGe call still in progress, whose end would have
run on the loaded CPU state. Also stop the camera and GPS when a state has
them off, don't restart capture when saving, and fix a double free of the
pmp frame queue (it only holds the media engine's own frame).

Reject sizes past the end of the state before allocating (FPL, PGF,
achievements, SAS grain, savedata list, the memory fast path), fail
instead of desyncing on a SAS voice count mismatch, and free what old
states' paths and shrinking pointer containers dropped.
Co-Authored-By: Claude Opus 5.5 (1M context) <[email protected]>
Containers of pointers are filled with nullptr and then DoClass'd, and
once an error switches the load to MODE_NOOP, every remaining element
called DoState on null.

DirectoryFileSystem reused one entry across files, so a failed reopen
could seek another file's handle. VirtualDiscFileSystem leaked every open
handle on each load. MemoryStick ignored the saved free space basis.

They were recreated without block size or extradata, which Atrac3 needs,
so it stayed silent after a load. Also drop the old decoders when the
state has none, and don't overflow on v1 states.

Delete the old HLE mips call actions instead of leaking them or keeping
stale ones, fail the load on an unknown action type instead of crashing,
and derive the exit-callback-pending flag from the loaded state.

The function list is from before the load, where other code (an overlay
module) may have been. Hashing it again from the loaded memory keeps the
hooks to code that actually matches.

With WLAN on and no server reachable, sceNetAdhocctlInit keeps its thread
waiting for the login. The load dropped the request, and the wait ended in
BUSY, which Init can't retry. Splinter Cell then ran its failure path with
a deleted event flag. Also stop freeing matching event buffers into the
restored allocator, and take the event lock when clearing.

The old icons stayed in PPGe's decimation list with kernel addresses from
before the load, and got freed out of whatever the loaded state had there.

Both drained only in their own DoState, after memory and Atrac contexts
had already been replaced under a mix or read still in flight. Also fix
sceUmd loading umdActivated into the wrong variable, and count each save
once in saveStateGeneration (it also bumped in the measuring pass).

KernelHeap was missing from CreateByIDType, and an unknown type returned
without an error, desyncing the rest of the load. States from before exit
callbacks kept the boot-time action slot, which sceMpeg's restore took over.

DoState replaced native_ while holding a lock_guard on its mutex, so the
old NativeInput could be freed before the guard unlocked it. Crashed every
state load (e.g. Splinter Cell Essentials, anywhere in the game).

since 7e6405291 only full 64 KB reads get cached, so any read touching the
shorter last block of a file came back short. count blocks with
blocks_.size() too, so failed reads can't inflate the count until
MakeCacheSpaceFor loops forever. also stop read-ahead from asking the
backend for blocks past the end of the file.
