Doc dir related changes coming up

[Ville Skyttä]

Hello,

Related to the unversioned docdirs F-20 feature [1], some changes with
doc packages will be needed in a bunch of packages. More info will
follow later, but I've started looking into the list of affected ones.
Some related things are still being discussed on the packaging@ mailing
list.

While assembling the list, I'll check which packages can be easily and
cleanly made independent of whether their docs install into versioned or
unversioned doc dirs, and will push and build those trivial changes to
rawhide already now.
