*: initial commit

This is a simple allocator derived from the chunker in the
sparkler rototiller particle system module.

It's useful for pooling allocations of varying size with a
lot of churn.  It also gives a convenient way of discarding
all allocations through a reset mechanism obviating the need
for granular freeing, where applicable.
