642b92b391 Introduce debug macro hooks for AVR
When AVR_HAS_MEMX_PTR is enabled provide dbg macro hooks that place
the format strings in program memory releasing RAM for other tasks.

556954141e AVR: Add support for AVR chips with 24-bit Program Counter register
The main challenge is to change the context switch code to be aware of the
extra byte that is saved on stack during call and intterupt. This relates also
to the task startup and signal handling.

41bdcd16b8 Change notation of PCH and PCL registers into PC0 and PC1
This is for forthcoming Atmega2560 support. The Atmega2560 has 24-bit PC
thus, PCH and PCL would become PCH, PCM and PCL (M for Middle). The problem
that in this notation PCM is equivalent to former PCH. This makes compatable
porting kind of difficult, at least for my taste.

Instead PCH becomes PC0 and PCL becomes PC1 (think of the index as order of
bytes pushed to stack when call is performed, PC0 as MSB goes first, PC1
goes to stack second, and for 24-bit PC, PC2 as LDB goes last).

0c1294d332 Introduce a new Kconfig variant for Atmega2560 and add some basic stuff
Modify Kconfig to be aware of the new chip.
Add all the interrupt hanler constants and vectors where needed.
Move contsatnts from generic to specific headers when needed.
