Fix for terrible performance in US versions of Primal (all the time) and Ghosthunter (when encountering Teddy Bear and in the moment of Gator-Man's rush attack, maybe few other cases), Both games use shared code with pretty dumb wait loops in the microcode, those are absolutelly unnecessary and significantly kill performance on emulator.
* Performance fix for Primal and Ghosthunter
Fix for terrible performance in US versions of Primal (all the time) and Ghosthunter (when encountering Teddy Bear and in the moment of Gator-Man's rush attack, maybe few other cases).

This change makes the EE recompiler not hardcoded to working with 32 MB of RAM, and instead work with the amount of RAM set in Ps2MemSize::MainRam. The rest of PCSX2 seems to work fine with more than 32 MB of RAM - it is only the EE recompiler that has trouble. If the Ps2MemSize::MainRam value is not changed from the default 32 MB, there should be no change: 32 MB / 0x10000 = 0x200, the value that was there previously.
This may be helpful if anybody else in the future wants to emulate a PS2 dev kit with 128 MB or RAM, or maybe the PSX dvr thing which I think has 64 MB of RAM. I've confirmed that with the change, you could set Ps2MemSize::MainRam to 128 MB, and execute code with the recompiler that's above the first 32 MB of RAM, and do VIF and scratchpad DMA transfers from this upper memory as well.
* Modify VU addressing so it only multiplies by 8 before entering the program
Fixes issues with VU1 TPC being read multiplied by 8 (bad)
* Removed assert on SuperVU which no longer makes sense
- Always enable sw colclip for BLEND_NO_BAR.
Free blending and it's faster than standard hdr algo when Blending
Accuracy is disabled.
- Enable sw colclip for Safe FBMASK SW emulated.
instead of hdr mode with accumulation blend so we don't use a mix of sw
and hw blending. It is more accurate.
Test case: Superman Shadows of Apokolips, fixes shadows when blending is enabled.
- Use const to get rid of some warnings.
- Free blending and it's faster than standard hdr algo when Blending
Accuracy is disabled.
- Add assert when disabling hw blending, hw blending should only be disabled
on free/no barrier blending. D3D11 lacks other types of blending.
- Use const to get rid of some warnings.
Fast floating point behaviour can optimise out handling for special
floating point values e.g. NaNs. As GSdx needs to handle NaNs in a few
places, precise floating point behaviour should be used instead.
Fixes a flashlight regression in Silent Hill 2/3 that was caused by
VS2019 optimising out NaN handling.
* Change the minimum cmake version to a range. Uses the new policies of the newer versions if you are on them, taking care of CMP0054.
* Grab a newer version of FindHarfBuzz.cmake from Webkit that fixes the cmake warning the earlier one was giving.
* Add in -ftime-trace as an option on build.sh.
* Precompile PrecompiledHeader.h if you are using cmake 3.16+ and GCC. (Currently disabled on clang due to compilation issues.)
* Check if target_precompile_headers exists rather than by version.

* spu2-x: Make portaudio an optional dependency.
v2: Fix crash in the audio settings with SDL1 and without portaudio.
* cmake: Add PORTAUDIO_API to disable portaudio support.
ePSXe for example.
There is little to no benefit in keeping it, especially when nobody was
maintaining the code. If we ever want to reintroduce it we can do so
from older branches like 1.6.
Plus if we want to integrate plugins into pcsx2 itself this is a required step.
PS1 games can ofc still be played within pcsx2.
Let's Make a Soccer Team!, Virtua Pro Football, Pro Soccer Club o Tsukurou! Europe Championship, World Football Climax.
Technicals:
SLES-54151 reads data from SLES-54153 to allow importing players. Same with the Japanese equivalents.
The above pairing in reverse allows importation of custom teams exported in 54151's VS mode. Again, same with the Japanese equivalents.
SLPM-66442 is listed in PCSX2 Wiki but not in GameIndex.
Leave it as an ini option only.
People should never use custom resolution as it causes many issues and
many features aren't supported with it.
On linux option was removed a long time ago.
