Bug#474034: ITP: gpxe -- PXE network bootloader for x86 PCs

[Vagrant Cascadian <vagrant@freegeek.org>]

well, i've updated debian/copyright as best i can, but the last few entries are
a bit dubious.

there are numerous files with no licensing claims other than upstreams headers:

  FILE_LICENCE( GPL2_OR_LATER );

there are some with no copyright holder.

there also numerous files with no licensing declarations whatsoever...

so i added:

 Files: ...
 Copyright: unknown
 License: FILE_LICENCE( GPL_ANY );

 ...

 Files: ...
 Copyright: unknown
 License: unknown

to at least document which need more work and clarification from upstream.

live well,
  vagrant
