Bug#1091933: ITP: ada-url -- WHATWG-compliant and fast URL parser

Package: wnpp
Followup-For: Bug #1091933

Hi, I forgot about this !

To sum up, the package is in somewhat good shape, except that
https://github.com/ada-url/ada/issues/827
upstream doesn't care about ABI versioning.

I just pushed a proof-of-concept for ABI checking,
so that the debian package maintainer knows when a soname bump is required.
At first I wanted to use dh-acc, but abigail-tools seem to have
an active upstream, and it's really easy to setup in debian/rules.

In that situation, the soname version will end up not being the
major version number of the upstream version, but that's not a problem.
