Use ffs() for finding timers from cycle timer map.

This optimization speeds up avr_cycle_timer_process() considerably. It
used to be a major bottleneck in my test case (52% of CPU time spent
in that routine), now it's about half that.

Message:
Return zeros when GDB reads just past end of stack.

GDB likes to read the topmost value of stack when using the
"stepi" (step instruction) command. Unfortunately this does not work
when the stack is empty, causing an error message and GDB confusion.

Hack the GDB stub code to just return zeros if GDB tries to read two
bytes just past the end of stack.

NOTE: This may need to be modified to support also longer reads for
bigger AVRs where code pointers are longer than two bytes (e.g.
ATMega2560). As simavr doesn't support atm2560 yet, I'm implementing
it this way now.

core: Added a new ELF tag with AVR->simavr command path

This new mode allow the AVR firmware to specify an (unused)
AVR IO register as a "command path" to send commands back to
simavr.
It allows for example the firmware to start/stop the VCD trace
dump, exactly where it should from the ooint of view of the
firmware being ran.

See atmega88_uart_echo.c for an example.

timer: Implemented some of the ICR based timers

Also made a PWM and a Fast PWM mode. Fast pwm doesm't use the
interrupts, as most of the time it's never used. Aldo it kills
