- in prep. for some restructuring to be able to better deal
  with very large file systems
- moved a utility function into index.go
- no functionality changes, only code reorg.

Old code was using recursion to traverse object graph.
New code uses an explicit stack, cutting the per-pointer
footprint to two words during the recursion and avoiding
the standard allocator and stack splitting code.

in test/garbage:

Reduces parser runtime by 2-3%
Reduces Peano runtime by 40%
Increases tree runtime by 4-5%

Also add exporter.Drain() to wait for completion.
This makes it possible for an Exporter to fire off a message
and wait (by calling Drain) for the message to be received,
even if a client has yet to call to retrieve it.

Once this design is settled, I'll do the same for import send.

Testing strategies welcome.  I have some working stand-alone
tests.

Solves the (English) peg solitaire game. The board is represented
by a 1-dimensional array for easy representation of directions
with a single integer. The board's contents are chosen such that
it can be printed with a direct string() conversion.
