Involves making asserts use printf instead of the log functions (log functions are asynchronous and, as such, the log won't be printed in time)
As such, the log type argument was removed (printf obviously can't use it, and it's made obsolete by the file and line printing)

Also removed some GEKKO cruft.

GSP SetBufferSwap fix

Services: Stub some functions

arm: Remove TRUE/FALSE defines

arm_dyncom_thumb: Make lookup tables static

FS: Allow multiple instances of the same archive type to be open at once

- Removed the Debug parameter from ARMul_State since it isn't used.
- Changed ARMul_CoProInit to a void function. It always returned true.

These don't need to be recreated all the time.

vfp: Normalize accumulator for multiply accumulate instructions

dyncom: Add more regs to MCR/MRC

Adds the registers that were left out of some coprocessor ranges.

Add more blend equations from 3dbrew

Scheduler refactor Pt. 1

* Simplifies scheduling logic, specifically regarding thread status. It should be much clearer which statuses are valid
for a thread at any given point in the system.
* Removes dead code from thread.cpp.
* Moves the implementation of resetting a ThreadContext to the corresponding core's implementation.

Other changes:
* Fixed comments in arm interfaces.
* Updated comments in thread.cpp
* Removed confusing, useless, functions like MakeReady() and ChangeStatus() from thread.cpp.
* Removed stack_size from Thread. In the CTR kernel, the thread's stack would be allocated before thread creation.

Mutex/synch fixes

vfpdouble: Fix the FTOUI NaN sign setting

This was fixed for vfpsingle, but not vfpdouble

Throw more unused/unnecessary VFP code out

Cleanup related to vfp_helper.

Appveyor: Do x64 builds

The submodule update was doing a full clone. Also increase clone depth a
bit, since it can apparently cause issues checking out the source if
there are too many concurrent PRs trying to build (causing the commit
for the build to not be the top one on the repository anymore).
