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.

when a module delegates to another module (as the activeqt ones do), it
doesn't have a master header to be included. we could derive the real
master header by doing a transitive dependency resolution and some
filtering, but that seems unnecessarily complex.

When qtbase has been compiled with PCH and trying to compile the

due the C++ includes. Guard the includes with __cplusplus to be
"usable" on C code. This guard is proposed for the "stable.h" in
the qmake precompiledheaders documentation.

We'll use the master depends header for the module as the precompilation
header. We could use the master include, but tests show that
precompilation benefits taper off for big precompiled headers. The
important part is to get the Standard Library headers precompiled.
Each module can still override which header to precompile by setting
PRECOMPILED_HEADER after load(qt_modules). It can also turn off
precompiled headers by setting that to empty or by CONFIG -=
precompile_header.
Testing a few build times shows the following improvements (GCC 4.8 with
-O3 and C++11):
QtPrintSupport: 14.7%
QtOpenGL: 22.7%
QtDBus: 29.5%
QtSvg: -2.4%
QtXmlPatterns: 26.1%
QtQml: 21.6%
QtQuick: 25.0%
QtMultimedia: 9.0%
QtSerialPort: -30.0%
QtHelp: 5.6%
The numbers also show that precompilation is worse for small modules.

let the syncqt + qt_module_header.prf pair handle generation of
forwarding headers.
in qtbase this is ineffective to some degree, as the need to create
QtCore's forwarding headers early for QtBootstrap requires qtbase.pro
already doing the real work, but at least we get the verification that
nothing breaks.
Other Modules (TM) will need the full functionality.

the logic in the configures was even trying to express that, only that
nowadays we always ship syncqt, so the tests were kinda pointless.
this frees us from the perl dependency for non-developer builds of
packaged modules (except for webkit, which needs almost every scripting
language on earth anyway).
obviously, this requires that the packaging scripts run syncqt in the
source dir before tarring up the sources. note that for repositories
other than qtbase, the -version argument needs to be passed to syncqt.
