This is used enough to warrant a builtin, rather than lisp implementation

This is an r7rs extension which allows you to extract a subset of the
vector.

Does what 'quotient' did before, now quotient rounds towards zero
while floor-quotient rounds down.

Instead of having a random set of stash arrays with explicit indices
used by callers, just have a general heap. Less error prone, and less code.

This inline was already defined; just use it. Also, switch some places
to use ao_scheme_is_pair instead as appropriate.

Unify output functions and add bool to switch between write and
display mode. Make that only affect strings (as per r⁷rs).
Use print recursion detection in frame and stack code, eliminating
PRINT flags in type field.

This lets BIGINT be a primitive type, allowing it to use all 32 bits
for storage. This does make strings another byte longer, and also
slightly harder to deal with. It's a trade off.

This provides for the creation of smaller versions of the interpreter,
leaving out options like floating point numbers and vectors.

Large ints, strings and floats can cause allocation, requiring that
the 'cons' pointer be stashed and retrieved in case it moved.
