core: Add a muxer for IO writes

It turns out that some core (tiny85 at the very least) are competing
for IO writes on some register.
This patch introduces a muxer callback that can call multiple clients

core: Introduce run() and sleep() callbacks

It seems that the default 'run_avr' function was penalized by
some tests made that were only useful when gdb was active.

This patch introduces two version of the critical run_avr, one for
"raw" running, and one for gdb.

It also introduces a sleep() callback for similar reasons. Ir can
also be used to run unit testing at 100% speed instead of having
random sleep code during execution.

timer: Fix a subtle off-by-one bug in TCNT reading.

There's a subtle bug in TCNT (timer counter) reading which only causes
the counter to ever run from 0 to TOP-1, while it should stay in the
TOP value for a full timer cycle before resetting to 0 (but the
interrupt needs to come when TOP is first reached).

Interestingly, this causes Arduino's micros() function to occasionally
return incorrect values. micros() function relies on TCNT0 not
transitioning from <= 254 to 0 in only a few cycles with /64

GDB likes to read the topmost value of stack when using the

ATMega2560). As simavr doesn't support atm2560 yet, I'm implementing
