David Guillen Fandos 4fd456e158 Adding Code Breaker cheat support
This works on both interpreter and dynarec.
Tested in MIPS, ARM and x86, still needs some more testing, some edge
cases can be buggy.

David Guillen Fandos 71ebc49b59 Improve indirect jumps in ARM
Handle already translated blocks in the ARM asm to speed up indirect
branches (affect some games more than others)

David Guillen Fandos a494a3f00e Move OAM update flag to a register
Fix a small bug in MIPS dynarec that affects non -G0 targets

David Guillen Fandos eab44b9e0b Enable runtime dynarec enable/disable
Added a more thorough cache cleanup for reset/mode-change too.
Fixed the mmap initialization that ends up leaking memory.
Minor x86 asm fixes for Android.

David Guillen Fandos fb7ca09b01 Remove BIOS reserved translation area
This is not really necessary since it can share area with ROM.
Performance impact should be very minimal (haven't noticed it myself)
and could be compensated (even by a positive offset) if we bump the ROM
cache area size.
Tested with several dynarecs.

David Guillen Fandos 5ffd2832e8 Rewrite of the MIPS dynarec stubs
This allows us to emit the handlers directly in a more efficient manner.
At the same time it allows for an easy fix to emit PIC code, which is
necessary for libretro. This also enables more platform specific
optimizations and variations, perhaps even run-time multiplatform
support.

David Guillen Fandos 5127f4b5cc Remove PSP-specific stuff from MIPS backend
This is unnecessary since newlib supports all file I/O.
This is needed for other mips ports

David Guillen Fandos 56dc6ecb70 Remove libco
This removes libco and all the usages of it (+pthreads).
Rewired all dynarecs and interpreter to return after every frame so that
libretro can process events. This required to make dynarec re-entrant.

Dynarecs were updated to check for new frame on every update (IRQ, cycle
exhaustion, I/O write, etc). The performance impact of doing so should
be minimal (and definitely outweight the libco gains). While at it,
fixed small issues to get a bit more perf: arm dynarec was not idling
correctly, mips was using stack when not needed, etc.

Tested on PSP (mips), OGA (armv7), Linux (x86 and interpreter). Not
tested on Android though.
