New savestate implementation
...
This uses BSON as savestate format, to allow external tools to parse it
(so that we can add proper test of the states). The BSON is not 100%
correct according to spec (no ordered keys) but can be parsed by most
libraries.
This fixes also a bug in the savestate palette color recalculation that
was wrongly overwritting the original palette (which could cause some
problems on some games).
Also fixes some potential issues by serializing some more stuff and
cleans up unused stuff.
Testing shows that states look good and there's only minor differences
in audio ticks, related to buffer sizes (since buffer flushes are
de-synced from video frames due to different frequency).

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 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.
