The po rescan hook re-runs the scan hooks, and runs the preprocess ones in scan
mode, both on the po-to-markup converted content. This way, plugins such as meta
are given a chance to gather correct information, rather than ugly/buggy escaped
data it did gather from unconverted PO files.
This reverts commit 4cf185e781.
That commit broke t/po.t (probably the test case only is testing too
close the the old implementation and needs correcting).
Also, we have not decided how to want to represent it yet, so I'm not
ready for this change.

(cherry picked from commit a128c256a5)
Set it to true every time IkiWiki::filter is called on a full page's content.
This is a much nicer solution, for the po plugin, than previous whitelisting
using caller().
The protection against processing loops (i.e. the alreadyfiltered stuff) was
playing against us: the template plugin triggered a filter hooks run with the
very same ($page, $destpage) arguments pair that we use to identify a already
filtered page. Processing an included template could then mark the whole
translation page as already filtered, which prevented po_to_markup to be called
on the PO content.
This commit only runs the whole PO filter logic when our filter hook is run by
IkiWiki::render, which only happens when the full page needs to be filtered.
In the process, lost the commits from special usernames
when committing changed po files. Instead of trying to dummy up a session
object for the special username, I just don't pass one, and the commit will
appear to be from whatever user ikiwiki runs as.
If po is imported twice, bad things happen. Guard against that.
I'm not sure what causes the double import; I saw it when websetup did a
wiki rebuild. Carp failed to show a backtrace for the second call to
import.
Note that there is an associated po4a warning when a page is empty:
Use of uninitialized value $file in substitution (s///) at /usr/share/perl5/Locale/Po4a/Text.pm line 205.
I've filed a bug with po4a about that, but the important thing is fixing
the crash here.
