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.

instead of saving the files away and restoring them afterwards, use the
new and shiny discard_from() function to throw away everything the files
might contain.
strictly speaking, this is not precise, as the pris may also use *=, -=,
and possibly other operations which cannot be trivially undone, but the
purpose is essentially to discard the special outputs of some features
which may affect subsequent tests, for which this is sufficient.
as a side effect, the failure to load qmodule.pri is not fatal any more
(like for qconfig.pri), to save the pointless effort of ensuring that it
exists.

Adapt configure.exe to use qmake to do most of the work of configuring
Qt. This unifies a large part of our configuration system between Unix
and Windows. configure.exe is now still doing the license check,
creating qconfig.cpp, building qmake, and not much more.
On the way, re-implement the still missing Windows-specific tests with
the new system.
The opengles2 vs. opengl-desktop conditions got a bit convoluted, as
Unix prefers desktop GL, while Windows GLES2 (via ANGLE). Superficially,
there is a circular dependency, but the platform scopes are supposed to
break it.

it is sometimes desirable to override values from the mkspec without
modifying (or wrapping) the spec itself. linux distributors do this on a
regular basis.
so far, we'd pick up CFLAGS, etc. from the environment, in a somewhat
autoconf-like fashion. however, over time, this approach proved
problematic: the concept doesn't mix particularly well with mkspecs to
start with, is unexpected (and therefore causes frustration), and
doesn't mix well with cross-building (at least the way it was realized).
ironically, it was implemented this way (quite a while ago) upon my
explicit request ...
the new mechanism uses explicit variable manipulations on the configure
command line, just like qmake itself understands. as it happens, this is
again quite similar to autoconf-generated configure scripts. however,
this time around we don't pretend to be actually autoconf-like, so we
also don't try to map any variable names (some of which have different
semantics anyway).
this commit also eliminates the last use of the QMakeVar() function,
so delete it and the underlying infrastructure.

so far, each library was distributed over a test and (optionally) a
'library' output of a feature. this was conceptually messy and limiting.
so instead, turn libraries into a category of their own.
libraries now support multiple properly separated sources, which makes
overriding them a lot saner. sources can be conditional to accommodate
platform differences.
as an immediate consequence, move (almost) all library references from
the config test projects to the json file.
a few tests were excluded, because they are doing somewhat magic things
that should not be handled in this bulk change:
- freetype: .pri file shared with actual source code
- clock-gettime: -lrt is conditional, and there is a .pri file which is
shared with actual source code
- ipc_posix: -lrt & -lpthread conditional
- iconv: -liconv conditional
the multi-source mechanism is used to make a variety of tests work on
windows, where the library name differs from unix (and sometimes between
build configurations). some tests still needed minor adjustments to
actually work.
on the way, fix up disagreements between manually specified libraries
and pkg-config lines (affecting several xcb-related tests).

never use $$system() directly, but instead use qtRunLoggedCommand() with
a newly introduced out parameter. that way we can print the command's
raw output, which should help debugging configure problems.
additionally, we now consistently check the exit code of all executed
commands, which should avoid confusing followup errors.
note that as a side effect some calls now use $$system()'s 'lines' mode
instead of the bizarre default splitting mode. this has no impact on any
of the cases, which is why it is basically a negligible style change at
this point.
however, qtLog() gained support for arguments with more than one element
to accommodate this.

standardize on the fields in the json structure being single strings in
which separate elements are quoted and space-joined (because quoting
is unlikely to be necessary in the json file itself, and this format
avoids the visual noise of array handling).
the quoting itself is expected to be qmake-compatible, which is assumed
to be the case for the output of pkg-config (it's actually shell-quoted,
but that's the same except in some not-so-relevant corner cases).
