Subject: export QT_NO_<foo> equivalents to the build system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

this makes it possible to properly exclude entire subprojects based on the
availability of features, rather than stuffing every single source file
with #ifdefs.

the defines are aggregated from the -qconfig <profile>,
-no-feature-<foo> and some other configure flags.

usage:

load(qfeatures)
!contains(QT_DISABLED_FEATURES, textarea): SUBDIRS += textstuff

Task-number: QTBUG-28102
