Rewrote timer code.
...
The new code is based on timestamps, rather than delays. This eliminates the
need to update every timer in timer_process(), which cost a non-trivial amount
of CPU time on low-end machines.
This involved changes to every user of the timer code, so this change almost
certainly introduces bugs.

Mix sound sources in 32-bit buffer, then clip to 16-bit for output. Fixes overflow in some situations, eg MegaRace on SB16.

Moved integer registers, PC and flags_* variables into new cpu_state structure. Reduces recompiled code size slightly, small speedup (1-3%).
