that way the users don't have to duplicate the connect everywhere.
as a side effect, MaemoPackageContents will have error reporting now.

externalize the error message and evaluation notification callbacks into
an own handler interface.

this fixes the recent appearance of qt_webkit_version.pri in all qt 4.7
based projects.

in fact, the patch does somewhat more: it makes the evaluator provide
the information to the higher layers which is necessary for a truly
hierarchical display of includes. TBD later.

Task-number: QTCREATORBUG-1590

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

partly by removing unnecessary calls, partly by providing minimalistic
reimplementations.
this gives a quite incredible performance boost ...

no point in re-parsing them over and over during the scan of a bigger
project ...

shaves off another 20% of the loading time of Qt 4.6.

there is no point in throwing away and re-recreating invariant data over
and over ...

shaves off ~15% of the load time of Qt 4.6.

makes forward delcs in headers possible

to be able to share the option object among evaluators, it is passed by
pointer.

only field_sep stays static and becomes a string - that's effectively
just a cache to avoid repeated construction.

this also removes the bogus special casing of various
filename-containing variables inside the pro parser.

After all I don't need all that stuff in the cmakeplugin, all i needed
is now bundled in debugginghelper.h/cpp

The Debugger, cmake and Qt4 plugin all need it. More refactoring to it
coming.

Details:  Free the whole ProFile*, ProItem*, ProValue* and etc
structure after parsing, that frees around 200Mb for projects.pro.

Details:  ProFileCache be gone, as is ManagedProFile, not to be missed.
Drastically simplified how ownership works.
