port qmake to qt creator's qmake language evaluator

this is a monster commit which does the following things:
- import the evaluator as-is from qt creator into qmake/library/
  - integrate it into qmake's makefiles
  - overwrite proitems.h with actual special types
- remove the parts of Option which are redundant with QMakeGlobals
- make QMakeProperty a singleton owned by Option::globals. the dynamic
  handling so far made no sense.
- make QMakeProject a subclass of QMakeEvaluator, with relatively few
  extensions

the changes to existing qmake code outside project.* and option.* are
minor. implementing the changes gradually would mean changing a lot of
code which will be just replaced in the next commit, so i'm not wasting
my time on it.
