only way for that to be open is if it was deleted, and checkpoint holds it open (which is not an issue to prevent rename).

Also, when renamed, the list of zombie dbs is updated with the new dname.

We run 'backward' recovery and 'forward recovery' on the item we turn around on, so do not set 'forward saw checkpoint begin' state
till we're in forward recovery.

git-svn-id: file:///svn/toku/tokudb@15849 c7de825b-a66e-492c-adef-691d508d4ae1

Added missing state transaction (turn around on checkpoint begin with no transactions)
Added error checking for unlink (anything but 0/ENOENT is real error)

Changes due to code review with Barry

Was not holding cachetable lock to access rwlock (whose mutex was cachetable lock).
This caused a race condition that you would sometimes grab the cachetable lock on exiting the lock but didn't have it before.

We believe this caused the deadlock
