ELF: Updated example firmware to generate new traces

Example firmware declares two traces that will generate a
trace file automaticaly when run with run_avr. The file is
created at load time using the .mmcu declarations.

ELF: Redone the .mmcu section

The section now uses :tags: that can be parsed regardless
of order, size, alignment and so on.
Also added tags to allow a firmware to register VCD traces

This allows very quick and painless trace generation of any IO

Added support for IRQ triggers on any IO register

Each IO address has it's own IRQ list now, dynamicaly
allocated when needed. It allows any code to register
an IRQ callback for any change made to any register.

Even registers that have no IO drivers (yet?) can be
monitored.

As a silver lining, this means any register or register bit
can be traced in a VCD file and displayed in gtkwave.
