Jason Wilder 56d85d44ad Use RemoveAll instead of Remove 
When a database is dropped, removing old segments returns an error
because the files are already gone.  Using RemoveAll handles this
case more gracefully.

Jason Wilder 562ccb6492 Add missing cacheLock/writeLock.Unlock calls 
If an error occurred in this code path, the locks would not be released.

Jason Wilder 4afb98ba8b Return error instead of panicing if we can't create a new WAL segment 
If a drop database is executed while writes are in flight, a panic
could occur because the WAL would fail to write to the DB dirs where
had been removed.

Partil fix for #4538

Jason Wilder 6db5429d06 Fix deadlock when closing WAL and flush is running 
Close acquired the cacheLock and writeLock in a different order than flush.  If addToCache was also
running in a goroutine (acquiring cacheLock), a deadlock could happen.

problems.
