Once qtbase is built and installed, save the CMAKE_INSTALL_PREFIX
that was used during the build, and set it when a consumer calls
find_package(Qt5BuildInternals).
This fixes a bug where syncqt can not be found when building qtsvg,
while the developer specifies CMAKE_PREFIX_PATH to find the Qt packages,
but does not set the CMAKE_INSTALL_PREFIX.

To implement this, create a new Qt5BuildInternals package.
All child Qt modules like qtsvg should use
find_package(Qt5BuildInternals) or
find_package(Qt5 COMPONENTS BuildInternals) in the their
top level CMakeLists.txt.
This will make the qt_build_repo() macros available.
For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH
pointing to the source folder that contains the BuildInternals
package.
For the other modules we actually use a configured and installed
package Config file.
This change moves variables that used to be written into the
QtCore Config file into the BuildInternals package. This way
things that are relevant only for building additional Qt modules
does not pollute the QtCore package.

Currently to build qtsvg we have some copy-pasted code to set up
the paths for QtSetup and QtPostProcess to be found.
To make it cleaner, introduce two new macros called
qt_build_repo_begin and qt_build_repo_end(). The first one
should be called in a child repo like qtsvg, right after
a find_package(Qt5) call, and the second one at the end of the
repo top-level CMakeLists.txt file.
In order for the macros to work, extract some of the variables
which were set in Qt5Config into Qt5CoreConfig instead. This
makes sure that it works also for find_package(Qt5Core) calls.

A non-prefix build is a build where you don't have to run
make install.
To do a non-prefix build, pass -DFEATURE_developer_build=ON when
invoking CMake on qtbase. Note that this of course also enables
developer build features (private tests, etc).
When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable
will point to the qtbase build directory.
Tests can be run without installing Qt (QPA plugins are picked up from
the build dir).
This patch stops installation of any files by forcing the
make "install" target be a no-op.
When invoking cmake on the qtsvg module (or any other module),
the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build
directory.
The developer-build feature is propagated via the QtCore Config file,
so that when building other modules, you don't have to specify it
on the command line again.
As a result of the change, all libraries, plugins, tools, include dirs,
CMake Config files, CMake Targets files, Macro files, etc,
will be placed in the qtbase build directory, mimicking the file layout
of an installed Qt file layout.
Only examples and tests are kept in the separate module build
directories, which is equivalent to how qmake does it.
The following global variables contain paths for the
appropriate prefix or non prefix builds:
QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR,
QT_CONFIG_INSTALL_DIR. These should be used by developers
when deciding where files should be placed.
All usages of install() are replaced by qt_install(), which has some
additional logic on how to handle associationg of CMake targets to
export names.
When installing files, some consideration should be taken if
qt_copy_or_install() needs to be used instead of qt_install(),
which takes care of copying files from the source dir to the build dir
when doing non-prefix builds.
Tested with qtbase and qtsvg, developer builds, non-developer builds
and static developer builds on Windows, Linux and macOS.

DBus1 (1.12) configuration file breaks PKG_CONFIG environment
variables and will thus prevent other libraries to be picked up
by pkgconfig. Main sympthom is that xproto is not getting picked
up anymore, which results in hundreds of lines of warnings about
this being printed.
Work around that by wrapping the call to find_package(DBus1) and
restoring the environment.

The pro2cmake.py file is now smarter, and can reapply "special case"
modifications after regenerating a CMakeLists.txt file.
This substantially lowers the maintenance burden when regenerating
many files at once.
See the special_case_helper.py file for details on how it works.
Make sure to commit the generated .prev_CMakeLists.txt file alongside
your CMakeLists.txt changes.
To disable the preservation behavior, you can pass -s or
--skip-special-case-preservation to the script.
To keep around temporary files that are created during this process,
you can pass -k or --keep-temporary-files.
To get more debug output, pass --debug-special-case-preservation.

Separate the logic to find all used libraries from the code that writes out
the link_library information into the CMakeLists(.gen)?.txt files.
This patch will remove some "PUBLIC_LIBRARIES Qt::Core" from generated files.
This is due to us handling some Qt libraries in special ways in some of our
add_qt_* helpers. These special libraries were added to the LIBRARIES section,
but actually they should be added to the PUBLIC_LIBRARIES section instead. Do
so now, so that the newly generated files do not break things again.

Add an --is-example switch to pro2cmake to make it generate these special

dbus1_linked is only evaluated to true when the dbus package is found.
If it was not found, then it makes no sense to link against the
_nolink target, because no package was found in the first place.
When the package is not found, QtDBus uses a minimal dbus header which
is included with QtDBus sources, so there is no need for the _nolink
target.
This amends cc141cc5c6 and fixes a build
failure on macOS.
