[PATCH] paldo Support

[Jürg Billeter <j bitron ch>]

Hi

Attached patch adds basic support for the GNU/Linux distribution
paldo[1] to NetworkManager. Distro detection in configure uses
lsb_release, I hope that's ok.

Ok to commit?

Can I commit future fixes for the paldo backend without explicit
approval?

Regards,

Jürg
