Log Message:
Add support for creating a WAPBL log in the filesystem.  Will
create an in-filesystem log on first "mount -o log" if one doesn't
exist, and will then continue to use same log in the future.  See
(soon to be added) wapbl(4) for more info.

Adds a new B_CONTIG low-level allocation flag that uses hints in
"struct ffs_inode_ext" to lay out an ffs file's data contiguously.

Thanks to Greg Oster for helping with the design of this and to
Antti Kantee for code review and suggestions.
