a little bit more information when lookup fails
...
Basically this should never, ever happen until I start reclaiming heap
memory. I believe the only reason it happens is unprotected writes to address
0 or thereabouts.

Another commit, another bugfix.
Some snippets from my currently exploding todo list:
- always investigate lookup errors immediately. Beyond the root cause, they should never happen at the moment, while we aren't reclaiming memory.
we should always return a more precise error message. Usually involving null pointer checks.
- on abort, print out stack trace
- emit mapping of labels to addresses during survey
- store a mapping of symbols somewhere in the code image
- stop allocating 1KB per token; expand space for tokens as needed

first passing test for macroexpand
...
In the process I spent a long time tracking down a stray TODO in 108write.subx
that I thought would abort but didn't since the switch to baremetal.
Then after I reintroduced that assertion I had to go track down a bunch
of buffer sizes. Stream sizes continue to be a huge mess.

literal macros

Current plan:
- some way to define macros. For now:
(def f (litmac litfn () (a b) `(+ ,a , b)))
- macroexpand will expand calls by passing them through the cdr
(f 3 4)
macroexpand: ((litfn () (a b) `(+ ,a ,b)) 3 4)
=> (+ 3 4)
eval: (+ 3 4) => 7
