kernel - Add overlapping buffer test to the buffer cache
* Add a test for overlapping buffer in bgetvp().
* Add a sysctl vfs.check_buf_overlap which defaults to enabling the
check invasively. Overlapping buffer cache buffers can be deadly.
0 - disabled
1 - checked and reported
2 - checked and panic (invasive) (default)
