Creating a precompiled header exclusively for a one- or two-file module
is wasteful. The time that it takes to build the precompiled source is
on the same order as a regular compilation, so enabling precompiled
headers for those modules just makes the build slower.
Also make it possible to override the precompiled header by just setting
PRECOMPILED_HEADER to empty.

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.

this wasn't possible when these headers were still generated by syncqt,
as the targets may have been still missing at that time. however, as we
do that now with qmake, forwarding the timestamps is perfectly possible,
and is consistent with what syncqt itself does for "regular" headers.
the immediate problem this solves: when the early creation of the
forwarding headers in qtbase.pro is removed, they get created only when
corelib.pro is processed. their timestamps would be after the timestamps
of the already built bootstrapped libraries. if now the project files of
these libs get re-created, qmake's not conditional-aware dependency scan
would add these headers to the libs' deps, thus causing them to be
re-built. the re-built tools would in turn cause all mocs and thus all
libraries to be re-built. this would be particularly problematic if it
happened between 'make' and 'make install' due to another bug ...

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.

We'll use the master depends header for the module as the precompilation

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%
