Remove unneeded stuff from pre-commit script

The check against an empty commit was not needed (it is only a security for the 1st commit after git init).
It could also possibly pose problems because of the redirection to /dev/null on some windows systems.

newline at EOF & fixed indent

video_core/core: Get rid of more warnings.

Qt: Silence a bogus warning printed when using the debug runtime

The Qt debug runtime prints a bogus warning on the console if you
haven't called makeCurrent since the last time you called swapBuffers.
This presumably means something if you're using QGLWidget the "regular"
way, but in our multi-threaded use case is harmless since we never call
doneCurrent in the rendering thread.

dyncom: Remove unused variables and parameters.

It's entirely unused. Also allows getting rid of more clunky macros.

GPU: Consolidate Pica state

HID: Stub DisableAccelerometer and DisableGyroscopeLow

gl_state: Fix a condition typo in Apply

VFP: Log as trace to get rid of spamming.

Service::Y2R: Support for grayscale decoding of specific formats

Implements unrotated planar YUV 4:2:0 -> RGB24 conversions in Y2R.
Currently only the Y (luma) channel is used, so the results don't
contain color. This will be added in a later PR at some point.

This is enough to get all currently know Moflex videos to decode. (Some
don't display on-screen due to seemingly unrelated reasons.)

Thanks to @archshift for doing the initial implementation which I
cleaned up and then fixed the 8x8 block mode.

dyncom: Eliminate clang warnings

Gets rid of a whole load of missing brace initialization warnings.

ResourceLimit handles shouldn’t be waitable

Kernel: Fix a warning introduced with ResourceLimit, and remove the fallback code to prevent it from happening again.

Thread reschedule and MOFLEX fixes

Use condition var to properly pause the CPU thread

CFG: Update the cfg service to be like other integrated services

Adds support for threaded pausing so citra doesn't spin wait on pause

core/video_core: Fix a few warnings when compiling on MSVC.

Implement svcBreak

GPU/DefaultAttributes: Let the attribute data from the loaders overwrite the default attribs.
