One of our compilers for emscripten coerces all signaling NaNs to
quiet ones, so won't do any actual signaling. Anyone relying on them
to do so shall be disappointed, so it's better that they know about it
at compile-time - or, at least, have the ability to find it out.
Put the signaling NaN producers (and remaining (test) code using them)
under the control of a feature that's disabled when numeric_limits
claims double has no signaling NaN. Assume the bootstrap library
doesn't need signaling NaNs. Sadly, until C++20 <bit>, there's no
contexpr way to test that alleged signalling and quiet NaNs are
actually distinct.
Added some auto-tests for signaling NaN, including that it's distinct
from quiet NaN. Any platform on which the last fails should disable
this feature.

The requirement to separate debug and release DLLs on Windows stems from
the Visual Studio C run-time library appearing in two different variants
(debug and release) and not mixing well. It's possible to perform builds
without optimzations and with debug symbols while linking against the
release version of the C run-time, but at the same time the debug
version of the run-time brings other developer visible advantages.
MinGW on the other hand does not have this distinction, does not ship
with separate DLLS and does also not require the VS C runtime library.
Therefore we do not need this separation for MinGW, which means that our
packages can be reduced in size and application developers wishing to
debug their applications do not have to use debug builds of the Qt
libraries or run into Qt internal debug code.

[ChangeLog][QtCore] Qt installations on the host system can now be
relocated, i.e. moved to other directories.
Add a new feature 'relocatable' that's by default enabled for
non-static builds
- on platforms where libdl is available,
- on macOS when configured with -framework,
- on Windows.
If the feature is enabled, the directory where plugins, translations
and other assets are loaded from is determined by the location of
libQt5Core.so and the lib dir (bin dir on Windows) relative to the
prefix.
For static builds, the feature 'relocatable' is off by default. It can
be turned on manually by passing -feature-relocatable to configure. In
that case, QLibraryInfo::location(QLibraryInfo::TranslationsPaths) and
friends will return paths rooted in the user application's directory.
The installed and relocated qmake determines properties like
QT_INSTALL_PREFIX and QT_HOST_PREFIX from the location of the qmake
executable and the host bin dir relative to the host prefix. This is
now always done, independent of the 'relocatable' feature.
Note that qmake is currently only relocatable within an environment
that has the same layout as the original build machine due to absolute
paths to the original prefix in .prl, .pc and .la files.
This will be addressed in a separate patch.

in addition to the actual library resolution, also resolve the headers
belonging to the library, to validate the include path, and possibly
ensure that the right version of the library is present.
the "include" entries were moved out of the "test" objects, and renamed
to "headers". this cleanly permits libraries without compile tests.
the headers were not put into the sources, because the variance among
the includes is generally orthogonal to the variance among the
libraries.
note that this - like the library resolution - provides no support for
darwin frameworks. consequently, the opengl libraries are excluded from
the conversion on darwin.
similarly, wasm is excluded (centrally), because emcc is magic and would
need advanced wizardry to be dealt with.
