cddb_lookup: Support multiline track response.

* This fixes bug #12808.
* Also, don't accept track numbers above 99, as that's the maximum
a CD supports.

cddb_lookup: verbose now dumps server response.

* The pretty dump output is now only used for the -d and -i options.

cddb_lookup: Added options, allow dump/verbose output.

* Added option to dump the track info, and optionally not write the
data back.
* Added option to use an alternative server.
* Added option to dump verbose track info.
* Added ability to query the CDDB without actual CD in the drive by
providing category and CDDB ID.
* Added help text.

cddb_lookup: Cleanup.

* Use BNode::WriteAttrString() over WriteAttr().
* Use stderr for error output, print error codes when available.
* Use BObjectList instead of just a BList.
* No functional change intended.

cddb_daemon: renamed to cddb_lookup, moved to /src/bin.

* It's now a standard command line tool that is launched automatically
via the launch_daemon whenver a volume is mounted.
