Ian Campbell 443701ef0c Replace FSF street address with canonical URL
As recommended in http://www.gnu.org/licenses/gpl-howto.en.html.

This is the result of:
$ git grep -El Mass\|Temple\|Franklin | xargs ./fsf.pl

Where fsf.pl is:
    #!/usr/bin/perl -w -pi.bak -0777
    my $repl = 'If not, see <http://www.gnu.org/licenses/>.';
    my $br = qr/(?:\s*\n\s*(?:[\*\#]|\/\/|\.\\" )?\s*|\s+)/;

    my $inwt = qr/[Ii]f${br}not,${br}write${br}(?:to${br})?the${br}Free${br}Software${br}Foundation,(?:${br}Inc\.,)?/;

    my $mass = qr/675${br}Mass${br}Ave,?${br}Cambridge,?${br}MA${br}02139,?${br}USA,?\.?/;
    my $franklin = qr/51${br}Franklin${br}St(?:reet)?(?:,${br}| - )Fifth${br}Floor,?${br}Boston,?${br}MA,?${br}02110-1301,?${br}USA,?\.?/;
    my $temple = qr/59${br}Temple${br}Place(?:,${br}| - )Suite${br}330,?${br}Boston,?${br}MA,?${br}021110?-1307,?${br}USA,?\.?/;

    s|$inwt$br$mass|$repl|m;
    s|$inwt$br$franklin|$repl|m;
    s|$inwt$br$temple|$repl|m;

The only remaining mentions of these addresses are in COPYING files which I
haven't touched.

Some of the changed files are imports from elsewhere, however
filtering them out is tricky, I think it is tolerable to have these
files be modified here and then perhaps reverted on the next sync,
since it's only 1-2 lines and obvious what is going on.
