1594e02c84 vblankmanager: Discard first non-missed frames after a missed frame 
Additionally fix some vblank limiting stuff for FSR at 4K.

This is our late frame.

e690b00f7b vblankmanager: Allow going back in time by fixed redzones 
Going back a little bit okay, it's when we use varying values to go back, we become divergent from target over time with varying clocks

2cac416000 vblankmanager: When calculating fps limiter sleep time, take the min of the rolling max frame time against target interval - redzone 
We account for redzone later, and don't want to go over vblank time and preceed into previous vblank or whatever here.

a5c660e54f vblankmanager: More value tuning 
Based on some rough data across a variety of games that are both GPU bound and also ones that are very not and cause GPU clocks to vary wildly

797ee59cbb vblankmanager: Estimate draw buffer time based on max rolling average draw time 
Handles spikes much better and allows us to have a lower buffer when not needed.

f3865a73bd Name our threads 
Unfortunately the name length is limited to 15 characters, and the
executable name is dropped from the name if we don't include it.

470756029d Stop using X11 events for vblankmanager 
Instead, use a pipe. Check if the pipe is readable in the
steamcompmgr event loop.

This avoids a roundtrip through the X11 server.

Closes: https://github.com/Plagman/gamescope/issues/201

9af5c3f254 Cleanup vblankmanager 
Keep everything on the same timescale.
Avoid using floats here when we can just use integer maths.
Add demarcations.
Misc. cleanup.

bb9d0cdf8f Use nanoseconds for vblank timing 
Avoids locking on-vblank
STL's clock's accuracy can be funky also.

Get rid of C_SIDE 
wlroots headers can mostly be included with extern "C" blocks. Two
exceptions are the use of `static` for array args and `class` as a
struct field. These can be #define'ed to avoid C++ build errors.

This allows the whole project to be built as a single C++ codebase,
without having to maintain hybrid header files.

4ca73da9f6 vblankmanager: initial system to let steamcompmgr know when to repaint 
For now just mark one repaint per refresh interval without any particular
alignment, as that can be hard to get in nested. We'll use the display
timing extensions for that later.

We'll have it align properly in embedded mode soon.
