License of files in Documentation/pictures and ability to distribute them unclear

[Don Armstrong]

There are a lot of files in Documentation/pictures which have no clear
license, and unfortunately, the git log for them isn't clear at all
either.

Some of them cannot be distributed by lilypond either, for example,
logo-debian.png is the Debian Restricted Use Logo.[1]

It's great that a lot of them have the source which they were built from
present, but there are some which are still missing the source. [For
example, logo-debian.png can (and probably should) be built directly
from the SVG[2] at the appropriate size (or just the SVG used).]
