Cleaning up kdelibs

Next to the other efforts for kdelibs modularization, there's also some cleanup tasks which needs to be done accross the whole kdelibs codebase. Tasks in here are probably more suitable for short term, bite sized involvement.

Note: For most of those tasks we try to put an estimation of the difficulty can be: easy, normal, hard (somewhat like in video games). ;-)

Status	Description	Contact
IN PROGRESS	Fix kfileplacesmodeltest (normal)	Benjamin Port
DONE	Move to kcoreaddons the tests in kdecore/tests that are actually tests for classes in kcoreaddons, except kurltest (easy)	Anne-Marie Mahfouf
DONE	"cp kurlmimetest.cpp kurlmimedatatest.cpp" and port the second one to KUrlMimeData (in order to test both the deprecated API and the new API). After that, move the old one (kurlmimetest) to kde4support. (normal)	Lambert Clara
DONE	Port kcmdlineargs from KUrl to QUrl, then move KUrl out of kcoreaddons, and into kdecore for now, final destination will be kde4support. (easy)	Matt Williams
IN PROGRESS	Port kdelibs from KProcess to QProcess (except kpty) (easy)	Matt Williams
DONE	Update qmimetype in kdelibs from the one soon merged to Qt5, port all of kdelibs to the API changes. (normal)	David Faure
DONE	Create a staging/kconfig framework out of kdecore/config + kdecore/kernel/kauthorized*. Code should be ready (no more dependencies on the rest of kdecore). (normal)	David
DONE	Port all of kdelibs from KGlobal::config() to KSharedConfig::openConfig(), adjust includes (easy)	Claus Christensen
TO DO	Port all of kdelibs from KMimeType to QMimeType, see KDE5PORTING.html for details (easy)	?	<{{{3}}}>
TO DO	move KProtocolInfo out of ksycoca, i.e. move it to KIO, and make KProtocolManager simply read from installed files on demand. (normal)	?	<{{{3}}}>
TO DO	One of the things we need to remove is all of the use of the Q_WS_* defines. (easy) git grep Q_WS_ Some of them should be ported to a Q_OS_ define (eg, some of Q_WS_WIN should be ported to Q_OS_WIN), but not all of them, so this can't just be changed with a script. It should be done manually. Some of them need to be ported to QPA (lighthouse) in some way.	?	<{{{3}}}> For a walk through example, see this thread
TO DO	Another thing that should be done is using Find packages from ECM or CMake. (normal) For example, run 'git grep find_package' in tier1/solid. Some of the results are provided by CMake, and some come from the local kdelibs/cmake/modules folder. The kdelibs/cmake/modules folder should not need to be used. For example find_package(Flex) in solid should be replaced with find_package(FLEX) which is provided by CMake. The goal is to be able to run cd tier1/solid && mkdir build && cd build && cmake .. && make for each framework. This is already possible with the itemmodels framework. It also works with solid, because the packages it searches for are optional and the FindFoo.cmake files are not found.	?	<{{{3}}}>
TO DO	Find out what should be part of the link interface and what should not be. (normal but long), details...	?	<{{{3}}}>
