Maintain inode count in super and log trees

Browse Source 
Add a count of used inodes to the super block and a change in the inode
count to the log_trees struct.   Client transactions track the change in
inode count as they create and delete inodes.   The log_trees delta is
added to the count in the super as finalized log_trees are deleted.
