Bug#650601: libpng is ready for transtion

[Tobias Frost <tobi@debian.org>]

This time with d-boot in CC...

Forwarding to debian-boot, as requested from Cyril.

Debian-Boot people, please take a look at #650601 -- the libpng16
transition which is now ready to be started. There are a few udebs
affected, which is tested as described below (following a request from
Cyril).

IMHO also the udeb part is ready for the transition, but I'm not in the
d-i topics.
