* Use 2 points of known true RSX code roots and follow them in order to peek at the current section of valid RSX code:
These roots are: current RSX instruction address and the last targeted address by a branch instruction.
Rewritten the following global utility constants:
`umax` returns max number, restricted to unsigned.
`smax` returns max signed number, restricted to integrals.
`smin` returns min signed number, restricted to signed.
`amin` returns smin or zero, less restricted.
`amax` returns smax or umax, less restricted.
Fix operators == and <=> for synthesized rel-ops.
* Use atomic waitables instead instead of global thread wait as often as possible.
* Add ::is_stopped() and and ::is_paued() which can be used in atomic loops and with atomic wait. (constexpr cpu flags test functions)
* Fix notification bug of sys_spu_thread_group_exit/terminate. (old bug, enhanced by #9117)
* Function time statistics at Emu.Stop() restored. (instead of current "X syscall failed with 0x00000000 : 0")
* Allow emulation to work without firmware
* Fix HLE prx path detection.
* Fix manual list loading bugs.
* Fix HLE gcm
* GUI: Fix fonts search
* GUI: Hardcode sprx list
Do not depend on /dev_flash/sys/external/ contents.
* Check zcull/tiles offset if bigger than max MAIN/LOCAL size.
* Check memory mapping of offset if location is MAIN.
* Check pitch/size for 0 as coming from hw tests.
* In addition: fix 'bound' check of tiles, seem to rely on the bits location is in.
* Add locks for zcull/tiles/displaybuffer binding.
* allow sys_rsx_device_map to be called twice: in this case the DEVICE address retrived from the previous call returned
* Add ENOMEM checks for sys_rsx_memory_allocate and sys_rsx_context_allocate
* add EINVAL check for sys_rsx_context_allocate if memory handle is not found
* Separate sys_rsx_device_map allocation from sys_rsx_context_allocate's
* Implement sys_rsx_memory_free; used by cellGcmInit upon failure
* Added context_id checks
* Throw if sys_rsx_context_allocate was called twice.
