c62803d243 atmega_common: disable interrupts prior to rebooting 
If the watchdog is being reset in another thread, then
the reboot will never take place. This commit disables interrupts prior
to setting the watchdog timer to 250ms. This functionallity was common
to all Atmega CPUs, so it was moved to atmega_common.

e0365e0bf9 atmega: use software interrupt for context swap 
Fixes #5745
For AVR based boards, three defines must be defined AVR_CONTEXT_SWAP_INIT,
AVR_CONTEXT_SWAP_INTERRUPT_VECT, and AVR_CONTEXT_SWAP_TRIGGER.
These defines are used to trigger a software interrupt used for context
switching.

When AVR_CONTEXT_SWAP_INTERRUPT_VECT is handled, the scheduler is run
and a context swap will happen if necessary, with the resulting thread
starting following the reti instruction. This results in threads running
at normal priority instead of at interrupt priority.

Atmega devices do provide a pure software interrupt. The method used
here for waspmote-pro and arduino-mega2560 is to use pin change
interrupts, set the pin to act as an output, and toggle the value to
simulate a software interrupt. The main limitation here is that a
physical pin is now occupied and must be defined for each board
supported by RIOT. On the plus side, it provides an easy method for
detecting context swaps with an oscilloscope.

eed73beaa1 cpu/atmega_common: prepare for atmega328p inclusion 
use generic avr/libc definition for conditionnal compilation.
eg: use #ifdef(PORTG) or #ifdef(TIMER_0_ISRC) instead of #ifdef(Atmega328p)
This is more generic and simplify future boards support.

2aec999900 cpu/atmega_common: generalize register/peripheral definitions 
Makes AVR register definitions dependent on what avr-libc defines
for a given MCU, rather then duplicating that effort here.
Definitions done in this way are based on functionality provided,
rather than a specific MCU device.
