Implemented the required calls to make it work.

CoreTiming: Added a new logging class Core_Timing.

dyncom: Partially emulate BXJ

Just in case some game studio let the intern write inline assembly or something.

DSP: Signal (faked) interrupt on every frame.

dyncom: Actually set the Q flag for SMLABB/SMLABT/SMLATB/SMLATT

Easy skyeye todo fix.

dyncom: Implement QADD/QSUB/QDADD/QDSUB

- Hack to work around games checking that the DSP event has been signaled by a real DSP interrupt.

AddressArbiter: Ported arbitration type 2 from 3dmoo.

Loader: Add support for loading NCCH ROMs with the .3DS extension

Mutex: Add the calling thread to the waiting list when needed

Stub the y2r:u service

citra-qt: Added license headers to files.

skyeye: Remove duplicate typedefs

This will happen when the mutex is already owned by another thread. Should fix some issues with games being stuck due to waiting threads not being awoken.

citra already has its own typedefs like this.

Frontends: Shutdown core when emulation is stopped

FileSys: Fix crash bug in DiskFile exposed by #400

FileSys: Fix a few memory leaks

(Thanks 3dmoo!)

Core: Change default CPU to dyncom.

dyncom: Implement SMLAW

VFP: Minor cleanup, functionally the same.

dyncom: Implement REVSH

Also joins the REV ops into one common place.

dyncom: Implement SMLALD/SMLSLD

Implemented the SaveDataCheck archive

dyncom: Implement SMMLA/SMMUL/SMMLS
