[Box Backup] Feature requests

[Joe Krahn]

A couple of feature requests for bbackupquery; some simple, some not:

1) Allow the use of object-id instead of the name in all cases.
    Instead of a '-i' flag, one could use a notation that is recognized
    by the filename parser, such as '//ID:00000734'. I chose double
    slashes, because it's the only way to ensure there is no filename
    conflict - Linux allows all but '/' and NUL.

2) Add 'One File System' support. This is easy: just check st.st_dev
    for rLocalPath, and don't save anything whose st_dev is different.
    (I'm testing this now.)

3) It seems that extended attributes, like user/group, are saved.
    If they are, how can I list them?

4) File size: any way to list the decrypted file size? If not,
    save this as another file attribute.

5) Maybe make attributes somewhat extensible, via a 'get_attributes'
    function that makes it easy for users to modify without delving
    into the main source code.
