David Guillen Fandos 84cd7b2934 Rewrite ROM buffer allocation
This improves the existing on-demand ROM paging and also breaks down ROM
buffers into 1MB blocks for platforms with memory fragmentation issues.

Fixed some potential RTC reg issue in said platforms too.
Fixed page pinning on interpreter (would crash due to LRU evictions).

David Guillen Fandos 37430f22c5 Small optimization (~2-4%) and whitespace cleanup!
Cleans up a ton of whitespace in cpu.c (like 100KB!) and improves
readability of some massive decode statements.

Added an optimization for PC-relative loads (pool load) in ROM (since
it's read only and cannot possibily change) that directly emits an
immediate load. This is way faster, specially in MIPS/x86, ARM can be
even faster if we rewrite the immediate load macros to also use a pool.

David Guillen Fandos 883f07f487 Fix small buf and add cheat error messages
Some minor formating too

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 11ec213c99 Make ewram memory lineal
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.

David Guillen Fandos f6f3a91039 Adding Normmatt's BIOS as a built-in BIOS
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).

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 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.

negativeExponent a3725fd81f Remove ewram from libretro api
- Removing RETRO_SYSTEM_MEMORY from retro_get_memory_data/size
  since its incompatible for 2 reasons:
1. gba uses at least 2 blocks of memory, which is not supported
2. the way gpsp's memory block are not contiguous (see memory
   descriptors)

negativeExponent d8225bb313 Add optional battery save using libretro save api
- Adds core option to allow battery saves using the libretro api
  (retro_get_memory_data/size)
- Initial save size set at 128KB and actual size is automatically
  determined internally by gba.
- This will always assume that a save file is supported since save
  size or type cannot be determined until gba tries to write to backup memory.
- A 128KB block of memory is used as buffer, similar method to VBA
  Next/Beetle GBA workarounds.

Justin Weiss 6a50b8a68d [3DS] Fix dynarec prefetch aborts
Similar fix to https://github.com/libretro/pcsx_rearmed/pull/390. The
Nintendo svcBackdoor can cause stack corruption if an interrupt
happens during it, this uses Luma3DS/Rosalina's svcCustomBackdoor instead.
