2021-03-23	Make ewram memory lineal	David Guillen Fandos
	This saves a few cycles in MIPS and simplifies a bit the core. Removed the write map, only affects interpreter performance very minimally. Rewired ARM and x86 handlers to support direct access to I/EWRAM (and VRAM on ARM) to compensate. Overall performance is slightly better but code is cleaner and allows for further improvements in the dynarecs.
2021-03-22	Adding Normmatt's BIOS as a built-in BIOS	David Guillen Fandos
	Add options to select whether to boot from BIOS (default is no, as it is now) and whether to use the original bios or the builtin one (default is auto, which tries to use the official but falls back to the builtin if not found).
2021-03-17	Remove BIOS reserved translation area	David Guillen Fandos
	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.
2021-03-16	Move a few more registers to context	David Guillen Fandos
	This gets rid of some more absolute addrs in the MIPS dynarec. Tested on several platforms, we should be good.
2021-03-15	Move palettes around to simplify MIPS dynarec	David Guillen Fandos
	Will move also OAM structures to gain a few cycles per load/store. Loads can also be optimized for an extra instruction per access.
2021-03-08	Remove libco	David Guillen Fandos
	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.
