The benefit of this setting was largely lost due to wfDebug() having
been replaced with calls to Logger->debug() for much of our code.

This is motivated by making ResourcLoader debug=2 able to make
its concurrent load.php requests more quickly during local dev.

This effectively reverts T49960. I was wrong there, thinking that
this variable has no reason for being. The vast majority of the time,
these aren't of interest on subresource requests. It's trivial
to enable when wanted, and any non-debug level messages still come
through either way, including PHP runtime errors, exceptions,
warnings, etc.

This seems to make load.php about 50% faster for local development
when using mediawiki-docker.
I used `ab` to perform a load.php request 300 times. The mean was
320-360ms before this patch (with and without DebugRawPage=false),
and around 120-140ms with patch (with DebugRawPage=false, default).

Title::getRootTitle will throw on invalid page titles. This can happen
when the page title contains a prefix that clashes with a registered
namespace or interwiki. For example when pages exist on a wiki, and
then the namespace or interwiki is registerered. These are meant to
be converted by maintenance/namespaceDupes.php.

The invalid page title could be viewed via curid= parameter.

In such situation, there is no way to re-create the Title object for
the given namespace and title. The only place where this happens during
a pageview is when the skin is trying to create a Title object for
the parent title (which is a shorter text of the otherwise mostly the
same title in the same namespace).

Workaround this by creating the string directly via the TitleFormatter
instead of creating the impossible Title object in the middle.

To do so, we move the relevant parts to a separate include file that's
included both by Setup and the test.

The --color-moved option is highly recommended when reviewing this patch
to verify correctness.

More tests to come.

The new class, UrlUtils, is usable standalone or as a service. Using it
as a service will just automatically load a few settings from site
configuration.

In addition to just making our code cleaner, this will enable making
some of Setup.php's dynamic configuration more sane.

Test coverage is all lines except invalid URLs -- I couldn't find any.

* Indicate whether a class is a service (to be found via MediaWikiServices)
  or a lower-level class for certain backend logic.

* Indicate how to create / where to get instances of non-service classes,
  e.g. point to the relevant service.

* Remove copy-pasta text in file docblock that is unrelated,
  and incorporate any relevant text into the class docblock instead.
