ETW tracing to generate custom events on hook execution

[morallo]

This would allow easy visualization of the frame rendering timeline in GPUView.
It will help modify the hook_d3d to optimize performance and reduce latency.

I would propose to emit one event each time a hook callback function is called, so it should be implemented in hook_main.

Before putting a big effort on it, do you think it makes sense @JeremyAnsel ?

An additional feature could be generating a ETW on demand for a list of given call instructions, provided by their address in a config file.
This would allow a low-overhead dynamic instrumentation of xwingalliance.exe useful for reversing and hooking analysis/design.
Hook_main would need to implement the necessary memory patching to capture the flow without altering the execution.
Is this second feature even feasible?

Thanks in advance!
