Specifically this moves the inits into the .text section.

This also move the data and bss segments into sram2 to give the heap and
stack more space to work with in sram1.

The problem was the BSS segment was not aligned with size 4,
thus the routine to clear the BSS segment was infinite looping,
clobbering everything in it's wake until it ran off the memory edge and
caused a hard fault.

This commit does a couple of things.

  1. Fixes the alignment issue in the linker script
  2. Panics if the bss/data segments are not aligned properly
  3. Makes the logging the _first_ thing to initialize. Much easier to
     debug that way!

These headers take inspiration from the linked list and array list
headers as a way to provide primitive templates in C. This time
they implement an AVL tree and Map template (which uses the AVL tree).

Included are relatively robust tests, though they could be improved.
