Android patch: https://android.googlesource.com/platform/external/libxml2/+/51e0cb2e5ec18eaf6fb331bc573ff27b743898f4
Fix upstream: https://gitlab.gnome.org/GNOME/libxml2/-/commit/5dca9eea1bd4263bfa4d037ab2443de1cd730f7e
The upstream patch has the slight consequence that some port values end up
negative when cast to a 32-bit int. A negative port though in the URL would
make the URL invalid. It is discussed if instead it would be best to prevent
the port from ever being negative. Upstream decided to leave the above patch.
