* fix(agc): keep the driver's per-thread scratch out of thread_local teardown
With MinGW's emulated TLS, a thread_local with a destructor in a DLL is
destroyed after its storage is gone: when a std::thread ends, winpthread
runs libgcc's emutls key destructor, which frees the thread's thread_local
storage, and only then does the loader's DLL_THREAD_DETACH run the DLL's
tls_atexit list, so the destructors run on freed memory. The queue worker
touches four of them in libSceAgcDriver (the dispatch-ahead map, the
pending waits, the draw-snapshot compare vectors and the image decode
memo), and Driver::stop's join of the worker then corrupts the heap.
Under cdb's checking heap agc_driver_draw_cache_reuse stopped at the
worker's exit with heap corruption in all 127 runs, with graphics
pipeline libraries, with APS5_NO_PIPELINE_LTO=1 and with APS5_NO_GPL=1.
Without it the damage shows intermittently, as exit 0xc0000374 (2 of 143
runs with a cold NVIDIA shader cache) or as a fault in whatever allocates
next, such as NVIDIA's compiler on the optimized-link thread (#2980).
These objects now live in HostThreadLocal, fiber-local storage that owns
them, as the recorder's buffers do since e424b6b7b.

* fix(libs): keep thread_local objects with destructors out of module teardown
The teardown order behind the driver's heap corruption holds in every
module: with MinGW's emulated TLS a thread's thread_local storage is freed
before the module's DLL_THREAD_DETACH runs its thread_local destructors,
so they run on freed objects. PreciseSleepUs's timer (used, among others,
by the video-out vblank thread) then closes a stale handle; libkernel's
directory path, socket waker and UUID random device, libSceRandom's random
device and libScePosixForWebKit's random device and host lookup free or
close stale objects. They move to HostThreadLocal. The other thread_locals
in the modules are trivially destructible or only built for Linux.

* test(libs): fail when a module registers a thread_local destructor
prx_thread_local_destructors lists the symbols of every built module and,
where MinGW's thread_local destructor support is linked in, disassembles
the module for calls to __cxa_thread_atexit outside libc's registration of
guest destructors. A module that keeps a thread_local with a destructor
fails it with the function that registers one: with main's libSceRandom
it reports sceRandomGetRandomNumber, and with this branch all 122 modules
pass, libc being the only one that links the support.

* fix(agc): keep the image memo behind its pointer
The image decode memo went into HostThreadLocal as the whole array. On
Linux, where HostThreadLocal is a plain thread_local, that put 1024 memo
entries into every thread's TLS block instead of one pointer. It keeps
its unique_ptr as before, now owned by HostThreadLocal, so Linux builds
the same thread_local as main.

About
Tool for automatic executables porting to Linux and Windows.
Includes a relinker that converts executable to the target system's native format and implementations of system prx libraries suitable for dynamic linking. No emulation or separate runtime process.

Status
* System libraries: percentage of the functions known to the project so far (declared in core/libs/prx), not of every PS5 system function. The total grows as more functions are declared.
Dreaming Sarah (2D platformer) runs at a stable 60 fps on a GTX 1050 Ti / i5-7500 3.4GHz.
Unsupported or unexpected states strictly throw std::runtime_error. what() is printed to stderr and the process terminates.
The shader recompiler successfully produces SPIR-V (validated via Spirv-Tools when built with ANYPS5_ENABLE_SPIRV_TOOLS).
Compatibility
See the game compatibility list for tested games and known issues.
Input mapping
SDL-mapped game controllers are supported, including analog sticks and triggers. Keyboard and mouse controls can be configured with an anyps5-input.ini file. See input mapping for the supported devices and configuration format.
