Bug#630830: xorg: licenses / copyright statements missing from copyright file

[Mike O'Connor <stew@vireo.org>]

Source: xorg
Version: 1:7.6+7
Severity: serious
Justification: Policy 12.5


The debian/copyright for this package is confusing to me.  It seems to try to
indicate that the copyright holder of this software changes depending on
whether this is a debian or a ubuntu package?  Can this be clarified?

There are licenses in the source code which are not present in
debian/copyright.  For example,  much of the software is GPL-2 licensed, but
there is no mention of the GPL-2.

There seem to be many copyright holders which should be listed in
debian/copyright which are not.

xsf-docs/COPYING specifies a copyright holder which MUST be mentioned in
debian/copyright in order to comply with the distribution license:
