Merge processMetadata() changes:
* Fix how the metadata string is generated. Don't include the " - " in the output if either artist or title are missing from ID3v1/Vorbis tags. * Print the correct error message when ov_open() fails. * Improve filename-based generation of metadata. Use a copy of fileName for basename(), which may modify its argument in some places where the old, weird POSIX implementation is used. Also, basename() is not infallible, but when it fails, it is annoying for us. Assert that it cannot fail since we feed it with path names < PATH_MAX (handled in playlist.c and configfile.c.) In short, make processMetadata() always return something more or less useful as long as the file in question can be opened. git-svn-id: https://svn.xiph.org/trunk/ezstream@12554 0101bb08-14d6-0310-b084-bc0e0c8e3800
