Change &str input args into impl IntoGStr

[jf2048]

Also changes strings with transfer=full to impl Into<GString>

I added new Bounds but not a new Transformation, if anything else requires this stack-callback approach then one could be added

Also added Transformation too to correspond to the new chunk type, so IntoStrV works as well

Same question here, can you create a draft PR with the changes this causes? :)

[sdroege]

There's also impl Into<GString> for the transfer-full case and impl IntoStrV for the "array of strings" case that would be useful to consider here.

analysis: Don't use IntoGStr for string params with length

Why not?

I added IntoStrV but I think we want to do gtk-rs/gtk-rs-core#978 first, I don't want to make gir subtract one from len() only to remove that later

Why not?

Those don't need to be nul terminated, it's fine for them to just be &str. I mean, I guess it could be AsRef<str> if we wanted

Oh right, that makes sense.

I think the futures change would be worth its own PR. That can be merged already :)
