Simplify open load handling for MIPS and fix other arches
...
Also rewrite a bit memory handlers for smaller functions.

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.

Move palettes around to simplify MIPS dynarec
...
Will move also OAM structures to gain a few cycles per load/store.
Loads can also be optimized for an extra instruction per access.

Fix x86 dynarec, broken by d10c4afe
...
The dynarec expects function args to be located in registers instead of
the stack, which is not the default calling convetion in GCC/clang.

Small fixes to division by zero
...
This causes crashes in PSP quite often in many games. Other CPUs might
(depending on the processor state) silently return zero or some
undefined value.
The fix is borrowed from ReGBA's codebase

Update RTC emulation

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.
