Almost finish the DEP5 debian/copyright.

There are some issues left:

 * Upstream problems, which aren't terribly worrisome since the FSF
   *never* sue anyone for acting in good faith:

   + gcc/doc/include/gcc-common.texi is wrongly-licensed:
     <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52207>

   + libiberty/at-file.texi has no specified license:
     <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52204>

 * The copyright/license status of patches is not really covered.

 * Some manpages (e.g. gcc(1)) contain different license grants from
   those specified for their source files. There does not appear to be
   a way to indicate this, if it is even meaningful at all.

None of these problems are actually new.
