rc_client frees a request's async handle right after calling back. The
error path didn't clear pendingAsyncCall_, so closing the screen after a
failed fetch aborted a freed handle. Switching between Top players and
Around me also overwrote the handle without aborting the old request,
which could then call back into a closed screen, or leak an entry list.

rc_client keeps raw pointers to itself in the callback data of award,
leaderboard submit and ping requests, so destroying it with one in flight
(disabling achievements mid-game) had the late callback write to freed
memory. Count requests per client, retire a busy client instead of
destroying it, and destroy it when its last request completes.
Request timeouts in naett are per operation and the plain HTTP client has
none for the body, so a retired client is also destroyed after 60 seconds
regardless. Its late callbacks are then dropped, leaking their data.
Clients are tracked by ID so a new client at a reused address can't get an
old one's callbacks. At app exit, pending requests are cancelled without
callbacks, so everything is destroyed immediately.

PreferredToolArchitecture has no effect; the MSBuild.exe that runs decides
the compiler host. The earlier note claimed otherwise, from a build that
passed by luck.

naett reports a connection failure as -1, which rcheevos reads as
RC_API_SERVER_RESPONSE_CLIENT_ERROR, a non-retryable client error. An
unlock or leaderboard submission during a network dropout was then
treated as a server rejection and dropped, on every platform using naett.
Map any non-HTTP result to RC_API_SERVER_RESPONSE_RETRYABLE_CLIENT_ERROR.

rc_client doesn't call back for a game load aborted by unload, or for
anything pending when the client is destroyed. g_isIdentifying or
g_isLoggingIn then stayed set, and IsBlockingExecution kept every later
boot on a black screen until restart. Quitting during identification, or
disabling achievements during a token login, was enough.

UWP compiled naett with the WinHTTP backend but never reported
SYSPROP_SUPPORTS_HTTPS, so achievement traffic and badge icons went over
plain http. When the media server redirected to https, icons failed.
A failed icon download also left the URL marked pending, so it was never
retried for the rest of the session. Mark it failed instead, and let
IconCache retry it after 30 seconds.
The set-completed badge also skipped RemoveHttpsIfNeeded.

Read as an integer, a float's bits are its log2 with the mantissa a
straight line between powers of two, scaled by 2^23, and writing an
integer back is the matching exp2. That's exactly the GE's
approximation, without log2/exp2/floor. pspPow now also returns 1 for
e <= 0 itself, so the callers drop their checks. Shader languages
without integers fall back to a true pow.

Without SSE or NEON, triangle pixels got the secondary color in place of
the primary one plus it, so lit triangles came out black. It showed as
the "unexplained" known failures on riscv64 and loongarch64, and broke
the new gpu/lighting/shademap there. Reproduced on arm64 by building
without NEON.

Environment map S and T are (N.L + 1) / 2 with L the light's vector as
lighting uses it: from the vertex to the light for point and spot lights,
a zero vector staying zero, and the half vector for a light that does
specular. Whether lighting or the light is enabled still doesn't matter
(gpu/lighting/shademap).
The vertex shader ID now carries the type and computation of the shade
mapping lights (the ubershader reads them from u_lightControl), so both
shader caches get a new version.
Fixes the hair shine in iDOLM@STER SP (#12376).

The viewer is at infinity along view space +z, so in world space, where
lighting happens, it's the view matrix's third column rather than
(0,0,1): turning the camera moves the highlights (gpu/lighting/specular).
The shaders read it from u_view.
In a Need for Speed Carbon frame replayed on a PSP, this and the pow

The shaders and the software renderer only add specular when N.L >= 0,
as the GE does (gpu/lighting/specular); the CPU lighter, used for points,
lines and rectangles, didn't check.

The GE computes these powers as exp2(e * log2(x)), with log2 and exp2
each a straight line between powers of two (Mitchell's approximation),
and only uses the top 4 bits of the specular coefficient's mantissa.
Through a highlight's falloff a true pow is 10-30 steps of 255 brighter
at the exponents games use. Measured in gpu/lighting/specular.

x86 normalizes with a bare _mm_rsqrt_ps, so normal lengths are only good
to about 3.7e-4 there and the 1e-4 check failed on every x86 CI job.
Compare direction after normalizing instead.

With animated control points the pole is only nearly degenerate, so the
vanishing derivative is rounding noise rather than exactly zero, and the
absolute threshold missed it. The resulting random normals still showed
as dark patches on Pac-Man Arrangement's ghosts (#12354).

Software transform expands each point, line and rectangle to four
vertices, and gave up on the whole draw when that didn't fit
VERTEX_BUFFER_MAX. Batching only counted input vertices, so a batch over
16384 points (or 32768 line or rectangle vertices) vanished silently,
whether it came from one PRIM or several merged ones. Count the expanded
vertices when batching, and submit a PRIM too big on its own in parts.

Compares the software tessellator's positions, normals, UVs and colors
against a longhand double-precision reference (Bernstein polynomials,
Cox-de Boor with clamped knots, finite-difference normals), across
Bezier and spline surfaces, edge types, poles and patch facing, so it
can be optimized with something independent to be wrong against. Also
reports vertices per second.

With only one patch, the open-last-edge adjustment assumed the first edge
was closed, so one knot interval came out as 2 instead of 1, and the
patch wasn't the Bezier patch a fully clamped cubic is. Positions were off
by up to about 7% of the patch.

Four tests had their own copy of "call this until N seconds have passed,

The GLES sampler uniforms and texture slots for the control points and

Where all the control points along a patch edge meet at one point, like
the top of a dome, one derivative is zero and so is the cross product,
and normalizing it gave NaN. Use the limit instead, built from the mixed
second derivative. Fixes the dark spots on the ghosts' heads in Pac-Man
Arrangement (#12354).

The release was counted down on the WebSocket thread, one step per poll
of host time however many vblanks had passed, so how long a scripted
press lasted depended on how fast the emulator ran, and scripted runs
went different ways. sceCtrl now releases it after that many vblank
samples, on the emulator thread; the debugger only reports when it's done.
Also: wsdbg's :screenshot works in headless with Vulkan.

On hardware the last part of a savedata shutdown runs at priority 0x20,
whatever the dialog's own thread priorities, so a caller at 0x20 gets the
CPU back first and sees SHUTDOWN, and one at 0x21 or worse only sees NONE
(pspautotests utility/savedata/shutdownstatus). We ended it at the access
thread's priority, so Freak Out, which calls ShutdownStart from 0x20 and
waits for SHUTDOWN, sat at 'Please press START' forever. NFL Street 3,
which calls it from 111 and then InitStart straight away, still gets NONE.

Taking the highest unused slot instead could steal one that a state event
restores later, as VBlankWake did to MicBlockingResume, which then had
nowhere to go. Also name the event in the assert.

Recorded on hardware (pspautotests threads/tls/timeout), a Tlspl
allocation follows the same timeout rule as the other waits, including
failing at once for 0 and 1us without writing the timeout back, which the
shared rule it moved to in the last commits didn't give it yet. Before
that it waited the raw timeout, ~30us short.

Priority-ordered waiting lists were sorted with a comparator wrapper per
object (msgpipe, fpl, vpl), or searched with a copy of the same function
(mutex, mbx). HLEKernel::SortWaitingThreadsByPriority() and
FindBestPriorityWaiter() now do both for any waiting list, of thread ids
or of structs with a threadID.
HLEKernel::ClearWaitingThreads() replaces the identical cancel/delete
loops in semaphores, event flags, fpl and vpl.

Semaphores, event flags, mutexes, lwmutexes, mbx, msgpipes, fpl, vpl,
tlspl and WaitThreadEnd each had their own CoreTiming event, handler
registration and savestate entry for wait timeouts, and their own function
to schedule one. Now one event (WaitThreadEnd's, renamed) times out all of
them, keyed by thread, and dispatches on the thread's wait type to a
timeoutFunc registered alongside the begin/end callback functions.
__KernelWaitCurThreadWithTimeout() starts such a wait, and the HLEKernel
helpers have overloads that use the shared event.
Old savestates still load: each object's section reads its old event id
and points it at the shared handler, so a timeout pending in the state
goes off as before. Checked with a state saved mid-wait by the previous
build, and with four games.
The one behaviour change: tlspl timeouts now follow the same hardware
rule as the others, where they used the raw timeout.

A state with more event types than are registered now was refused, so no
event could ever be removed or merged. Loading now keeps the extra slots:
modules that still know an old event restore it to a handler, and the rest
stay placeholders that do nothing.
