Lioncash de9c5fd375 ConfigManager: Convert GPUDeterminismMode into an enum class
Makes the values strongly-typed and gets more identifiers out of the
global namespace.

We are forced to use anything that is not "None" to mean none, because
X11 is garbage in that it has:

\#define None 0L

Because clearly no one else will ever want to use that identifier for
anything in their own code (and is why you should prefix literally
any and all preprocessor macros you expose to library users in public
headers).

Lioncash 50a476c371 Assert: Uppercase assertion macros
Macros should be all upper-cased. This is also kind of a wart that's
been sticking out for quite a while now (we avoid prefixing
underscores).

Stenzek c790077c13 VideoBackend: Remove PeekMessages method
The video thread and backend no longer create any windows, therefore
there will never be any messages dispatched to their thread.

Shawn Hoffman ed8f293b4f Change "blocking" BlockingLoop::Stop to give up and die after a timeout.
This fixes the global-static fifo object causing infinite hangs in some
cases. Notably, failure to initialize a graphics backend would result in
BlockingLoop::Prepare being called but never executing Run(), leaving the
object in a bad state.

FIFO_SIZE is a u32, so %u can just be used instead.

Lioncash 62db55dee2 Fifo: const correctness
PushFifoAuxBuffer only memcpys data using ptr as the source pointer, so
it can be a pointer to const data because of that.

Léo Lam dca22e08eb Use Common::Flag and Common::Event when possible
Replaces old and simple usages of std::atomic<bool> with Common::Flag
(which was introduced after the initial usage), so it's clear that
the variable is a flag and because Common::Flag is well tested.

This also replaces the ready logic in WiimoteReal with Common::Event
since it was basically just unnecessarily reimplementing Common::Event.

EmptyChaos 5adb29b6cb Fifo: Call AllowSleep instead of Wakeup when pausing.
BlockingLoop was being woken when the emulator was being paused
which would cause the loop to busy spin. Issue 9692.

degasus cf4478dc92 Fifo: Fix SyncGPU.
CBoot::BootUp() did call CoreTiming::Advance which itself blocks on the GPU,
but the GPU thread wasn't started already. This commit moves the SyncGPU
initialization into the Fifo.cpp file and call it after BootUp().

degasus d31bed8b79 Fifo: Rewrite SyncGpu
The new implementation has 3 options:
 SyncGpuMaxDistance
 SyncGpuMinDistance
 SyncGpuOverclock

The MaxDistance controlls how many CPU cycles the CPU is allowed to be in front
of the GPU. Too low values will slow down extremly, too high values are as
unsynchronized and half of the games will crash.
The -MinDistance (negative) set how many cycles the GPU is allowed to be in
front of the CPU. As we are used to emulate an infinitiv fast GPU, this may be
set to any high (negative) number.

The last parameter is to hack a faster (>1.0) or slower(<1.0) GPU. As we don't
emulate GPU timing very well (eg skip the timings of the pixel stage completely),
an overclock factor of ~0.5 is often much more accurate than 1.0

comex 06dd0ba3b4 Exit ReadDataFromFifoOnCPU, PushFifoAuxBuffer early if shutting down (GpuRunningState=false)
This was causing a race condition where the "absurdly large aux buffer"
panic alert would be triggered in the last bit of fifo processing on the
CPU thread in deterministic mode (i.e. netplay).  SyncGPU is supposed to
move the auxiliary queue data to the beginning of the containing buffer
so we don't have to deal with wraparound; if GpuRunningState is false,
however, it just returns, because it's set to false by another thread -
thus it doesn't know whether RunGpuLoop is still executing (in which
case it can't just reset the pointers, because it may still be using the
buffer) or not (in which case the condition variable it normally waits
for to avoid the previous problem will never be signaled).  However,
SyncGPU's caller PushFifoAuxBuffer wasn't aware of this, so if the
buffer was filling at just the right time, it'd stay full and that
function would complain that it was about to overflow it.  Similar
problem with ReadDataFromFifoOnCPU afaik.  Fix this by returning early
from those as well; other callers of SyncGPU should be safe.  A
*slightly* cleaner alternative would be giving the CPU thread a way to
tell when RunGpuLoop has actually exited, but whatever, this works.
