Reduce memory footprint:
- use file buffer for all block reads - only save a small amount of the indirect block list Allows i386 bootxx_ufs code to load /boot from a filesystem with 32k blocks while still fitting inside 64k of memory. Code size reduced as well (by ~1k on i386). It ought to be possible to use a buffer that is smaller than a filesystem block. This might be needed in order to boot from filesystems with larger block sizes.
