* Update to 8.10.0

* Fix version detection in `systest`

Factor in both major/minor instead of just minor. This has been broken
for awhile since the 8.0 release.

* Fix compilation against system libcurl for me

Doesn't actually break the bindings since the underlying Rust type is
still the same, but gets things running locally at least.

* Fix bindings for `curl_version_info_data`
