[BUG] gio::DataInputStream::read_upto fails because FromGlibContainer::from_glib_full_num is unimplemented

[luleyleo]

Bug description

I wanted to read an entire file using gio::DataInputStream::read_upto but it fails when calling FromGlibContainer::from_glib_full_num here.

That can and should of course be implemented :) Do you want to provide a PR for that, or should I?

[luleyleo]

@sdroege I would have to figure out what exactly these functions are supposed to do and how any of this works first. So if you already know what to do here, I would greatly appreciate it if you could take care of this :)
If not, I can dig into this myself.

[sdroege]

Sure, will do that tomorrow. I just didn't want to do it right away in case you already started

[sdroege]

See #1238

[luleyleo]

@sdroege Thank you!
