Implement new dynmem_start() and dynmem_end() functions instead of
alloc_chunk() and alloc_chunks() in the board code. This simplifies
the board code.

Avoid using linker magic to define the init, task, and shutdown
functions. Instead, use the compile_time_request system. This
simplifies the build and produces more efficient code.

Introduce a new board function alloc_chunk() to allocate dynamic
memory. This allows the board code to implement memory allocations
without using the standard malloc() interface.

Most of sam3x8e/timer.c is going to be platform agnostic for any board
with standard irq handling. Move the generic code into a new file
generic/timer.c.

The irq handling in sam3x8e isn't specific to the sam3x8e proccessor -
it's generic for all armcm type machines. So, move the definitions
into a new file generic/armcm-irq.c

This adds basic support for running on the Atmel SAM3x8e
micro-controllers that are found in the Arudino Due boards.
