various fixes, gc can handle running the whole test suite
...
in a loop hundreds of times. the heuristics for growing
the heap still cause it to grow very slowly over time,
but nonetheless slower than boehm.

not trying to adjust the heap, just keeping a linked list
...
of heap chunks. expanding the heap thus works now, so i've
removed all the debugging utils from gc.c, except the conservative
checks which are now a config option.

test suite now passes with new gc, even starting
...
with a tiny heap and causing multiple allocations.
pointer adjusting after a moved realloc still segfaults.

don't sweep the free-list elements!
...
implementing heap expansion w/ realloc.
realloc is always giving back the same pointer right now,
so pointer adjusting not tested yet.
