Add dbfs, an example (re)fuse file system which mounts a Berkeley
database as a file system.
The file was created in the first place with the following commands:
cp /etc/passwd infile
db -E B -w -f infile -F: -C btree bdb.db
and mounted as follows:
./dbfs bdb.db /mnt
Example use is as follows, using a btree-based database with login
names as the key, and the rest of the passwd file entry as the value:
