HAMMER - Add vfs.hammer.yield_check, yield on cpu intensive loops
* When running in the kernel HAMMER can wind up cpu-bound. This code
allows it to yield to other processes during these periods. This is
a bit of a hack and may undergo further development.
* Default check for yield every 16 B-tree iterations.
