Note range of existing chunks to exclude objects outside.
Only look at chunks which have been set to reduce loop cost.

altos/lisp: Add incremental collection2017-02-20T19:16:51+00:00Keith Packardkeithp@keithp.com2016-11-16T20:34:14+00:00urn:sha1:c8f9db184cc929ebde845730a6d4b7864e423a84
Realizing that long-lived objects will eventually float to the bottom
of the heap, I added a simple hack to the collector that 'remembers'
the top of the heap the last time a full collect was run and then runs
incremental collects looking to shift only objects above that
boundary. That doesn't perfectly capture the bounds of transient
objects, but does manage to reduce the amount of time spent not moving
persistent objects each time through the collector.

altos/lisp: Append a CRC to the saved image to validate on restore2017-02-20T19:16:50+00:00Keith Packardkeithp@keithp.com2016-11-12T07:34:54+00:00urn:sha1:33aeffc123af1f9063969acf585f1caac885ced4
The CRC is actually of the ROM bits, so we can tell if the restored
image relates to the currently running code.

altos/lisp: Separate out values from atoms2017-02-20T19:16:49+00:00Keith Packardkeithp@keithp.com2016-11-03T05:56:01+00:00urn:sha1:11cb03b1d336ee90c422be27588f57be573a9546
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.

altos/lisp: Change lisp objects to use ao_poly everywhere. Add const2017-02-20T19:16:49+00:00Keith Packardkeithp@keithp.com2016-11-02T04:14:45+00:00urn:sha1:d2408e72d1e0d3459918601712b09860ab17e200
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.
