This is both faster, and propigates any error in processing the feedpages
pagespec out to display on the page. Which may have been why I didn't use
it before, but currently seems like a good thing to do, since it explains
why your feeds are empty..
If a page is taken from the underlay, and one of the specified languages
does not have po files in the underlay, it would create a broken link
to the translated version of the page for that language.
With this change, there's no broken link.
I think the N/A was not intended to be visible, but it can show up as the
percent translated to a language. This happens if the page is located in an
underlay, and not translated to the language in any other underlay.
Previously, [[!meta redir="foo"]] on bar, where bar/foo exists, would
depend on "foo" (which matches nothing, probably) rather than "bar/foo".

Previously, [[!img bar.jpg]] on foo, where foo/bar.jpg exists, would
get a dependency equivalent to "glob(bar.jpg)" (which might not match
anything), rather than the correct "glob(foo/bar.jpg)".

During backlink calulation, all links are examined and broken links can
be detected for free, so store a list of broken links and have brokenlinks
use it.
Exposing the %brokenlinks structure is a bit ugly, but the speedup seems
worth it: Around 1 second for wikis the size of the doc wiki that use
brokenlinks.
By adding this setting, we get both more configurability, and a minor
optimisation too, since gettext does not need to be called continually
to get the Discussion value.
