* Store the revision ID associated with a log entry if the action is successful.
* Expose this as a diff link in the UI.
* Implicitly hide log entries if their corresponding revisions are also hidden.
* Includes scope for expanding to log entries if desired.
Most of the rest cannot get a context since it originates from hooks with no context sources. Instead of just getting the main context we might as well wait for a proper solution.
Instead pass the Article object from the EditFilterMerged hook to the AFComputedVariable object and see whether the object is present to do a parse operation since other code paths won't pass an Article object
Also simplified the fallback code in AFComputedVariable::compute() to simply continue instead of calling the function again.
* ActiveAbstract: output is stored XML, as I understand it, so use canonical URLs throughout
* AbuseFilter: URLs go into log entries and need to be fully-qualified for the format to work
* EmailCapture: URLs go into e-mails
* SecurePoll: one URL goes to an XML file, make that one canonical. Made the URLs identifying users canonical too, because they would otherwise change when $wgServer is made protocol-relative and possibly break SecurePoll. Of course this means SP might still break if and when we change $wgCanonicalServer to point to HTTPS, but we'll worry about that later
* DoubleWiki: the surrounding code looks scary, but from what I can tell it seems to assume the URL starts with a protocol, then derive some data from it and put it in memcached. That means a canonical URL is needed so the protocol assumption is still valid and the cache isn't polluted
* OAI: use canonical URLs throughout
* LiquidThreads: use canonical URL in e-mail
* Internalise $mAddress/$mUser, $mBy/$mByName, $mEnableAutoblock, $mId as getTarget(), getBlockers(), isAutoblocking(), getId().
* This required editing AbuseFilter and CheckUser backwards-incompatibly, so push the rest of the changes out to those extensions.
* Attack the evil 14-parameter constructor and gratuitously-confusing newFromDB( $notVeryImportantParameter, $moreImportantParameter)
* Reimplement the hack for bug 13611 in a slightly less fragile fashion; could still do with further cleanup, but then again the login frontend is its own can of worms... :S
* Remove transitionary getTargetAndType() and newFromTargetAndType() methods
* Some optimisation in parseTarget()
* Fix the broken phpunit test mentioned in r84251
* Implement accessors for isHardblock() and getRangeStart()/getRangeEnd() in the same fashion.
* Make the corresponding variables private, removing external accessors. This required updating AbuseFilter with non-B/C code, so I also implemented the rest of the changes I've made to the blocking backend in that extension.
* Move the "get an IP range which encompasses the given IP/range" logic to Block.php; will be needed later... :D
* Move Block::parseExpiryInput() to the frontend SpecialBlock::parseExpiryInput()
* consolidate the several implementations of the MediaWiki:Ipblockoptions parsing into SpecialBlock::getSuggestedDurations()
