Added test to scribble over a database while it is being checkpointed.  (Uses checkpoint callback mechanism to guarantee timing.)

A memory leak is exposed by src/tests/root_fifo_1.c
It gets cleaned up when the transaction commits, but our VM could grow unbounded meanwhile

Fixes #1683 Created separate toku_cachetable_minicron_shutdown() to be called when no locks are held.  Note, toku_cachetable_close() still calls minicron_shutdown() if it was not already shut down to avoid rewriting tests.

Closes #1680 Moved assertion that cachefile is not in a checkpoint to when a cachefile actually closes
instead of just reducing reference count.
