interrupts: Now track pending and running states
Introduced two new IRQs per vector; one to track pending, and one to

Also introduced a global pending/running IRQ, so you can track issues if

It is reasonably transparent, and seems to have had little impact on the
rest of the code... Hooray for nice clean APIs!

Avoid buffer overrun on smaller AVRs
Avoid buffer overrun on smaller AVRs
On smaller AVRs, such as the attiny13, MAX_IOs will be larger than the
size of SRAM which will lead to out of range writes to a malloc
allocated buffer. Therefore limit the number of bytes cleared to the
size of SRAM.

sim_avr.h: increase MAX_IOs by one to 280
ATmega2560 has UDR0 at 0x136 = 310
sim_core + sim_regbit: use 16 bit integers for IO addresses
This is necessary on the larger ATmegas (e.g. ATmega2560).

This fails currently because IO addresses >= 256 are not handled correctly
