  Log Message:
  -----------
  Create 'SNEK_INVALID' value for snek_binary type error checking

SNEK_NULL *is* a valid retun from the array operation, so we can't use that
to flag type errors in binary operations. Create a new value, SNEK_INVALID, to
use instead.

  Log Message:
  -----------
  Use snek_chunk_t for var iterating over chunks

snek_chunk_t is defined to hold SNEK_NCHUNK, so it's safe to use that
instead of snek_soffset_t when snek_chunk_t is 8 bits, and we need to
use snek_offset_t when snek_chunk_t is snek_offset_t to avoid
signed/unsigned compare warnings.

  Log Message:

  Make posix pool much larger

This allows large snek programs to run in the posix build.

  Add port to SiFive HiFive1 revb

This references freedom-metal remotely, so building will
require that be available.

  Log Message:
  -----------
  Add conditionals to control building hifive1revb and esp32 versions

These two ports require software outside of snek to compile, so use
SNEK_HIFIVE1REVB and SNEK_ESP32 to control whether to try to use them.
