Remove video vars serialization
...
This is not needed at all, since the variables are not updated between
reload and end-of-frame (where we take our savestates). Added a reload
call during gba_load_state() to initialize it from the I/O regs.

Fix inifinite loop in the interpreter, fixes ~6 games
...
Seems that, on IRQ, it is assumed that the PC will change (which happens
most of the time). However if the IRQ is masked it resumes execution.
On masked DMA IRQ the interpreter jumps to alert without incrementing
the instruction pointer (right after).

Fix and reenable Android arm 32 bit builds

Removed the last bits of text relocations by moving all relevant RAMs to
the stub reachable area. This should be as fast or even faster than
previous code.

Move membuffers close to dynarec area to fix x86 relocs

This essentially makes it easier to get a relocation-free text area for
x86 so that Android loaders are happy.

Fix DMA VRAM mirror overflow and small 1-off error
...
Seems that this could make VRAM overflow big time and overwrite IWRAM
most of the time (since it lives after that buffer). This causes a
variety of errors, some of them hidden if IWRAM not used.
Most games do not use VRAM mirror so it's not a big deal, but some do
have a off-by-one errors that trigger this.

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).

Rework ram block ptrs to remove second indirection table.
...
This removes ram_block_ptrs and encodes the pointer directly in the
block tag. Saves ~256KB at no performance cost.
Drawback is that it limits the ram cache size to 512KB (we were using
768KB before). Should not be a problem since most games use less than
32KB of cache anyway.
Fixed ARM routines accordingly.

This is the format used by PS2.
This requires fixing the palette conversion routines (and palette writes
in the MIPS dynarec) but also adding support for 555 mode blending
(currently only 565 modes are supported, regardless of whether they are
RGB or BGR).
