Modified Files:
	src/sbin/fsck_lfs: bufcache.c bufcache.h

Log Message:
Fail gracefully if we are asked to expand the buffer cache hash table size
when there is no memory available to do so.  Use the uvnode's strategy
routine to retrieve data from the device, rather than always using pread().
Add a buffer header flag that specifies external management of the buffer's
data area.

All of this in support of a new cleaner, which is not included in this commit.
