We now use a different approach to setting up our
uninstalled python environment:
We add the gst-python folder to PYTHONPATH, and it no
longer contains __init__.py files. This means that
import gi.overrides correctly loads pygobject's __init__
module, but import gi.overrides.Gst also works, as __init__
files are no longer required by python.
Currently, gst-uninstalled is using sitecustomize.py for adding gi
override tweaks. However, if the standard Python libraries come before
this file in sys.path, then sitecustomize.py will never be run because
the "import sitecustomize" done in site.py will use the standard Python
libraries instead. This can be seen by running "import sitecustomize;
print(sitecustomize.__file__)" inside the uninstalled environment, as
well as by checking gi.override.__path__ and seeing that the tweaks are
missing (and the overrides are misbehaving).
Switch to using usercustomize.py, which has no match in the standard
libraries and thus will be correctly imported.

We should not default to -Werror because that's not what we default to
anywhere in gstreamer, and it's bad for releases anyway. The CI will
be fixed to pass --werror manually.
Don't assume that meson is always a python script, on Windows it can
be (and soon will almost always be) an executable.

Meson was literally trying to check out tag/revision
'a1b3f07c5271f312997fcc3451237031444c4475 # 1.8.0 + fix for gcc 8.'
which doesn't exist of course.
Can be re-enabled again if we check for all direct and
indirect hard deps before including it.

This would not trigger on the build bot because there is
special casing in the code for a meson checkout underneath
gst-build. Fix needed as mesonintrospect.py was changed into
'meson.py introspect' in recent meson versions. When using
meson from git to configure the build the uninstalled script
would pick up a system meson instead which then would then
error out parsing the coredata from the newer meson.
The proxy-libintl meson build files have been upstreamed, so we do not
need to use Centricular's git repository anymore.
Glib has moved to GNOME's Gitlab instance, and we use a specific branch
on it to get override_find_program for glib tools.
