Implement the remaining bytecodes. Adjust some of the numbering.
...
Also, use #<undefined> for "not yet initialized" and #f for "no value".

Update list of weak boxes *after* processing finalizers.
...
It's a bit unlikely, but a finalizer could be arranged for a weak box.
Also add more assertions, clear old range in debug builds, and misc. cleanup.

Added built-in structure types and interpreter core (w/o bytecode).
...
Improved timing resolution by using clock_gettime() instead of clock().
Also gave project a name: Rosella. Play on 'Parrot' (Perl 6 VM).

Add support for weak boxes and wills/finalizers.
...
Also refactored some GC code into smaller functions.
Weak boxes and wills will be useful for implementing weak hash tables,
which in turn will be used to store dynamic parameters efficiently.

...
Also, allocate GC memory ranges dynamically during startup (gc_init()) rather than statically.
