interrupts: Now track pending and running states

Introduced two new IRQs  per vector; one to track pending, and one to
track running state. So you can see any latency issues.
Also introduced a global pending/running IRQ, so you can track issues if
your interrupts overrun etc.

It is reasonably transparent, and seems to have had little impact on the

fifo: prevent potential misuse of _get_write_size()

Using the number obtained from _get_write_size() and writing that many
items to the fifo yields to _isempty() becoming true and not to
_isfull() becoming true.

I got caught assuming the latter.

To avoid thinking about edge cases and prevent potential misuse of
_get_write_size(), I suggest that it returns one unit less, thus, a
number between 0 and (fifo_size-1).  E.g., if there is only one place
left in the fifo, i.e., _isfull() is true, it then returns 0, preventing
us to fill that place and get into a wrap overflow situation.

(Michel: Thanks for the great architecture you laid out and the great
code.)

* static avr_cycle_timer_reset_sleep_run_cycles_limited() added.
sets new run_cycle_count based on present list of cycle timers.

examples: Extends i2ctest to include a second TWI driver

Adds a commonly used alternative to the Atmel TWI driver. This
particular driver is choosen because it covers a non-interrupt
driven approach to using the TWI module.
