The CRC is actually of the ROM bits, so we can tell if the restored
image relates to the currently running code.

This enables changing values of atoms declared as constants, should
enable lets, and with some work, even lexical scoping.
this required changing the constant computation to run
ao_lisp_collect() before dumping the block of constant data, and that
uncovered some minor memory manager bugs.

This makes all lisp objects use 16-bit ints for references so we can
hold more stuff in small amounts of memory. Also adds a separate
constant pool of lisp objects for builtins, initial atoms and constant
lisp code.
Now builds (and runs!) on the nucleo-32 boards.
