  Log Message:
  -----------
  Switch atmega32u4 devices to ubaboot

This bootloader takes only 512 bytes of flash, leaving
plenty for snek to operate on all of the 32u4 targets.

Create a general-purpose atmega32u4 snek installer and
replace the single-device versions.

  Log Message:
  -----------
  Use __flash for AVR code instead of PROGMEM

This uses the GCC memory space attribute so that the compiler will
automatically generate the correct memory access instructions instead
of requiring manual use of various progmem APIs. This both simplifies
the code and reduces its size.

  atmega328p: Increase pool and value stack

The new version of GCC leaves more RAM available; take advantage of that
by increasing the heap size to 1kB and the value stack to 32 elements.

  chips/atmega: Handle EEPROM that doesn't start at 0

On the atmega4809, avr-libc doesn't set E2END to be the last offset,
rather it's the last address. Use EEPROM_SIZE instead, which seems
to be the size - 1.

  Enable more features due to newer avr-gcc version

The newer GCC version generates smaller code, so we can
enable the input builtins on all of the avr targets now.

Until debian's avr-libc gets updated, we'll need to use a custom version
while using debian's avr-gcc. This just points the includes and libraries
at a version installed in /opt/avr-libc for now.
