Several of our tools are installed and are used by other projects to
generate code. However, there is no 'install' when projects use glib
as a subproject, so we needed some way for glib to 'provide' these
tools.
Starting from Meson 0.46, this can be done with the
meson.override_find_program() function. This also means that we can
use these tools ourselves via the GNOME module and don't need to
manually create command-lines.
This assumption breaks when, for instance:
* Called as /bin/gdbus-codegen
* Installed on Windows in a directory that is not `bin/`
For such cases, we cannot make any assumptions about the directory
structure, and must hard-code the datadir.

Disable gio tests on Windows, fix .gitignore to not ignore
config.h.meson, and add more things to it.
Rename the library file naming and versioning to match what Autotools
outputs, e.g., libglib-2.0.so.0.5000.2 on Linux, libglib-2.0-0.dll and
glib-2.0-0.dll on Windows with MSVC.
Several more tiny fixes, more executables built and installed, install
pkg-config and m4 files, fix building of gobject tests.
Changes to gdbus-codegen to support out-of-tree builds without
environment variables set (which you can't in Meson). We now add the
build directory to the Python module search path.
