[dynarec] "Fix" ARM-mode STM instruction writeback
...
Move writeback to the end of the instruction (instead of the start).
This is also wrong but fixes some common cases (ie. push sp).

Remove gpsp savegame method in favour of libretro's one
...
This generates 128KB save files (instead of variable sized ones) to
prevent truncated savegames under some circumstances. Most other
emulators have no trouble loading them (and the unused data is simply
ignored).
Remove also config txt file that's now unused.

Adding DMA transfer "Sleep" mode
...
This accounts for DMA stealing cycles from the CPU whenever the CPU
triggers a DMA (does not affect H/V blank or sound DMAs).
Works by moving the CPU to a PAUSED state where the cycles are accounted
for, reusing a similar mechanism for HALT/STOP.
Fixes a couple of games, notably GTA that has a DMA/IRQ race condition
(likely a bug really) if cycles are grossly miscalculated.

Improve savestate loading to avoid corrupting the current state
...
It should not happen since the magic value and version would normally
discard incompatible savestates, however it's preferrable to check
before loading the state (it's just some minor sanity check).
