-z nodelete breaks the libresourceplugin module usage in the resources.c
test, which expects to be able to unload it.

Make the Meson build match what the autotools build does: only pass
glib_link_flags to the headline libraries (glib-2.0, gio-2.0,
gobject-2.0, gthread-2.0, gmodule-2.0) and omit it from all other build
targets.

This requires improved pc file generator from meson 0.45.

Properly define GLIB/GOBJECT_STATIC_COMPILATION when static build is enabled.
Use library() instead of shared_library() to allow selecting static builds.

configure_file() forces utf-8 atm but .rc files are not utf-8.
To work around the issue just remove the only non-ASCII char.

Don't use it project-wide for building everything. Otherwise
symbols for shared modules won't be exposed, e.g. in the
resourceplugin used by the gio resource unit test.

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.

Several small fixes to the build files.

Lots of tests have also been added, and glib tests pass now.
