Make CBFS output more consistent
- Prefix all CBFS output messages with CBFS:
- Add an option DEBUG_CBFS that is off by default. Without DEBUG_CBFS
enabled, the code will no longer print all the files it walks for
every file lookup.
- Add DEBUG() macro next to LOG() and ERROR() to specify which messages
should only be visible with DEBUG_CBFS printed.
- Actually print a message when the file we're looking for was found. :)
