dbd: remove orphaned ._ AppleDouble files. Bug #549.
Automatic conversion for OS X ._ AppleDouble files, bug #550

Add automatic on-access conversion for ._ AppleDouble files created by
OS X to Netatalk's AppleDouble format.

OS X .AppleDouble files most of the times contain a FinderInfo
AppleDouble entry with a size larger then 32 bytes, containing packed
xattrs. Netatalk fails to cleanly deal with these and logs them as
"bogus entry id 9".

Fix a crash in of_closefork(), bug #551

Apparently dirlookup() might return NULL when trying to query the did
of an open fork:

    dir = dirlookup(ofork->of_vol, ofork->of_did);

Add a NULL check before using the result.
Don't print message "Ignoring ._file" for every ._ file, bug #552
