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.

Logging: Log all called service functions (under trace). Compile out all trace logs under release for performance.

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.

Also replaced C headers with the C++ equivalent ones

- cleaned up window title
- cleaned up emu_window_glfw/emu_window
