This updates the copyright header to all be the same, which is pretty much an update of where to mail request for a copy of the GPL and the years of the MPD project. This also puts all committers under 'The Music Player Project' umbrella. These entries should go individually in the AUTHORS file, for consistancy.

/**
|
|
*
|
|
* archive_lookup is used to determine if part of pathname refers to an regular
|
|
* file (archive). If so then its also used to split pathname into archive file
|
|
* and path used to locate file in archive. It also returns suffix of the file.
|
|
* How it works:
|
|
* We do stat of the parent of input pathname as long as we find an regular file
|
|
* Normally this should never happen. When routine returns true pathname modified
|
|
* and split into archive, inpath and suffix. Otherwise nothing happens
|
|
*
|
|
* For example:
|
|
*
|
|
* /music/path/Talco.zip/Talco - Combat Circus/12 - A la pachenka.mp3
|
|
* is split into archive: /music/path/Talco.zip
|
|
* inarchive pathname: Talco - Combat Circus/12 - A la pachenka.mp3
|
|
* and suffix: zip
