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.

If descriptor contents stay the same but version goes up, record new version (instead of ignore it).

Serialize descriptor with each brtnode (leaf and nonleaf) 
Deserialize descriptor with each brtnode (to be thrown away). 
    Don't malloc+memdup the descriptor for brtnodes, since that would waste time.




git-svn-id: file:///svn/toku/tokudb@11200 c7de825b-a66e-492c-adef-691d508d4ae1

Added versioning to descriptor.
Changing a descriptor REQUIRES the version to increase.
Version 0 is reserved for a non-descriptor db. (cannot be set).
Not yet added to brtnodes.
Still possible to change descriptor with an open brt (which would not be upgraded).
