dyncom: Move over SMLALXY

Remove dead platform #ifdefs to make the code more readable.

Archives: Change the folder layout of some archives.

It now refers to me as the PoC

Symbian, Xbox, Blackberry and iOS got removed.
FreeBSD and Android kept due to them potentially being able to run Citra in the future.
The iOS specific part also got removed from PPSSPP in order to fix a bug there.

Renamed all .hxx headers to .h

Added exclusive reservation granule from ARMv7 spec to dyncom...

Remove x86 specifics

Services: Clean up a few things and add a few function names

Silence some -Wsign-compare warnings.

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
