That is e.g. buildSteps() and cleanSteps() --> steps(type)

The functionality was duplicated between the Qt4 and CMake build
configurations and their configuration widgets. This change moves it
down to BuildConfiguration, in addition also making it available for the
Generic Project.

Also provides an upgrade path for the configuration.

This is a big change touching almost all of our .pro file parsing.
With this patch we only evaluate once exact for all needs and once
greedy for the filelist. That is the qt runconfigurations don't have own
evaluaters but reuse the project wide exact evaluation.

We reevaluate if the user changes the build directory, the qmake
buildconfiguration or the qmake arguments. That is if you open src.pro
(or projects.pro) of qt with a shadow build you still don't get all the
files, but after correcting the build directory, we reevaluate the .pro
files and find all files. So for a suitable definition of fixed, that
bug is now fixed.

We now get the exact defines of all .pro files instead of all defines for all
buildconfigurations. We still don't distinguish in which
.pro file a DEFINE is set. So the code model now knows about all the
defines set for the given configuration but not for which files it is
actually set. Also that includes all DEFINES set in .qmake.cache or the
mkspecs. This means all defines from .pro files should now work.

The intial loading is still synchronous. I haven't looked into it to
deeply, but it seems possible to make it also async.There are probably a
few issues which need to be solved fist.

Also due to the asynchronous nature of the code, the executable is
updated a few seconds after actually changing the build configuration

They do what you expect them to do, that is build only a subtree.
The implementation is a little bit strange. We temporarly set the sub
node to be built on the BuildConfiguration, enqueue that
BuildConfiguration (which calls BuildStep::init()), and then reset that
temporary value.

A more general way would be to have the ability to extend
BuildConfiguration::buildProject() in a way that additional data can be
passed to the BuildSteps.
