Previously, we performed casts that are considered undefined behavior.
Instead, just define ssize_t for nghttp2 the same way we define it
for the rest of Node.

Also, remove a TODO comment that would probably also be technically
correct but shouldn’t matter as long as nobody is complaining.
(And is therefore unlikely to ever be implemented.)

Would we have to float this patch on top of nghttp2 forever? Can we submit something upstream?

LGTM on the change itself.

Would we have to float this patch on top of nghttp2 forever?

It’s not really a floating patch – config.h is an automatically generated file that we checked into our repository, it doesn’t exist upstream.

Can we submit something upstream?

I don’t have the links to the other issues where this was brought up at hand here. The “upstream” source of the arguably bogus #define ssize_t int is autotools itself, and submitting a patch there seems doable but also like a major breaking change for the whole autotools ecosystem, so I wouldn’t expect us to be able do anything about this.

We could do something like suggested in nghttp2/nghttp2#1008 and try to replace the usage of ssize_t in nghttp2 altogether. ¯\_(ツ)_/¯

Should this be backported to v9.x-staging? If yes please follow the guide and raise a backport PR, if not let me know or add the dont-land-on label.
