This macro expands into a static_assert and can be used to
trigger a compile error if a certain feature is not available
when trying to compile some code.
This is especially useful to protect against accidental inclusion
of headers that implement functionality related to a feature.

This change implements the required infrastructure to modularize the new
configuration system.
This requires a hierarchy of configuration files, both for handling
multiple repositories and for individual modules inside the same
repository.
When configuring, they all need to get loaded first, as command line
processing needs to know about all possible command line options.
When the command line has been processed, the individual configuration
files need to get processed one after the other and independently from
each other.
Configure is now automatically invoked when building the a project
tree's "root" project; this works with both modular and top-level builds
of Qt (the latter with an according change in the super repo). As an
immediate consequence, the -skip option moves to the super repo with a
different implementation, as configuration is now done after the repo
list is determined. The option belongs there anyway.
This commit also adds an optional testDir entry to the json file. Like
this, we can still have all configure tests in qtbase/config.tests and
the configuration file in, e.g., corelib can reference those.
The files section can now be left out as long as a 'module' entry is
present, specifying the module name. The names of the files to generate
can then be deduced from that name. We still need to be able to specify
names directly for the global configuration files.
qtConfig() now also queries features which are module-specific. As it is
sometimes necessary to query the configuration of modules which should
not be actually linked (and cannot in the case of subdirs projects), the
new variable QT_FOR_CONFIG which allows specifying configuration-only
dependencies is introduced.

Test each include file directly, instead of doing a large #include. This
verifies that each header is compilable on its own. One big advantage of
doing it via a special compiler in qmake is that we skip pre-compiled
headers, which has hidden build errors in the past.
This solution is implemented by making syncqt produce a second list of
headers. This list is the same as the list of headers in the source
code to be installed, minus the headers that declare themselves to be
unclean, via the pragma:
#pragma qt_sync_skip_header_check
This mechanism is applied only for public libraries (skipping
QtPlatformSupport, an internal_module).
This test is enabled only for -developer-builds of Qt because it
increases the compilation time.
On QtTest: the library only links to QtCore, but it has two headers that
provide inline-only functionality by including QtGui and QtWidgets
headers (namely, qtest_gui.h and qtest_widget.h). If those two modules
aren't getting compiled due to -no-gui or -no-widgets to configure, we
need to remove the respective headers from the list of headers to be
checked. If they are being built, then we need to make QtTest's build
wait for the headers to be generated and that happens when qmake is
first run inside the src/gui and src/widgets directories.
