Summary:
In kconf_update, the ctime usage used to be about metadata change time
(buff.st_ctime, before it got ported to the misnamed created()).
I ported it to birthTime, because I think
date of birth is a more useful way to identify a file than
date of permission change which doesn't really matter to us.
But in practice, I can't help but wonder if mtime alone wouldn't be
enough.

For the QStringLiteral("%%1").arg(i) bit, I tested it in tst_qstring,
the first % is left untouched.

Test Plan: make && ctest

GIT_SILENT

Summary:
the wiki page says the readme is duplicated into the wiki.

so, what we end up with is either

- they end up out of sync
- someone gets real angry because the wiki needs format markup while the
  readme must not have markup
- someone doesn't get angry and simply copies either markup or nomarkup to
  the respectively unsuitable target

it's an unsustainable situation... so instead let's point the readme to
the wiki and consider that the place where the documentation is maintained

Summary:
the previous logging tech got kind of defunct in 2014 (to the point where
it was basically qCDebug). seeing as no one really complained it seems
reasonable to just move to qCDebug instead and make use of category filters
and other qdebug goodness (such as system logging facilities for the
various platforms)

- new logging category kf5.kconfig.update; at info level by default (i.e.
  unless otherwise configured kconf_update is now silent)
- --debug cmdline option now also attempts to force-enable the debug mode
  on that category (and debugs that attempt in of itself, so we don't get
  confused by categories magically getting enabled).
- all log() calls are now qCDebug calls
- all logFileErorr() calls (which was context-sensitive to the .upd file
  parsing) have been changed to qCDebugFile
- qCDebugFile is a new *macro* wrapping around qCDebug to give it file
  context
- everything is now qCDebug instead of qDebug
- arguments updated to drop excess quoting and spaces to reduce "noise"

Test Plan: updater still works and debugs when debug is enabled

they are unused, but if anyone would use them things would go wrong, so
protect us from it
