KConfig* API overhaul. only cosmetics, so don't panic.

KConfigBase:
- remove separator argument from list entry reading/writing functions
- introduce {read,write}XdgListEntry()
- kill readPathListEntry(), add readPathEntry() overload
  instead. the default value is not optional any more, as it defines the
  return type. this is consistent with the readEntry() functions.
- rename clean() => markAsClean(), remove rollback()
- rename ConfigState => AccessMode, getConfigState() => accessMode()
- rename {entry,group}IsImmutable() => is{Entry,Group}Immutable()
- remove NLS alias to Localized

KConfig:
- remove setGroup() & group()
- reshuffle OpenFlag enum, introduce NoCascade for symmetry
- remove setExtraConfigFiles() alias to addConfigSources()

KConfigGroup:
- inherit KConfigBase::deleteGroup() overloads
- make convertToQVariant() private, it will probably change somehow

- KConfig & KConfigGroup: deprecate entryMap()
- remove bogus declarations: KConfigGroup::setReadDefaults(),
  KConfig::readEntryUntranslated()
- apidox
- reshuffle the declarations in the headers
