New "Imperative" Syndicate Implementation

This experimental reimplementation of Syndicate takes the language-level constructs of facets, endpoints, and fields to heart, and integrates knowledge of facets and endpoints into the dataspace implementation itself.

It gains a significant performance advantage by doing so.

Programs seem to be about 20x faster. Some are only 10x faster, some are 30x faster.

The prototype that embodies the new idea is in prototype.rkt.

All the drivers end up looking much nicer with this new implementation. The previously-separate GL-2D support is now integrated as just another driver (though the timing characteristics of the old implementation are not precisely preserved). The ground.rkt implementation is much cleaner.

The implementation test suite lives in test/.

Try out the "many Racket logos" animation example/demo:

racket examples/gl-2d-many.rkt

Hopefully you'll get a smooth 60fps, though I admit I'm running it on a fairly fast machine so you might need to drop the sprite-count in the code a bit to sustain 60fps.
