8acdf66540834b9f9cf28f16d389e8b6a48516d5 upnp: add compatibility for miniupnpc 2.2.8 (Cory Fields)
Pull request description:
Fixes https://github.com/bitcoin/bitcoin/issues/30266
Miniupnpc 2.2.8 [changed the function signature of `UPNP_GetValidIGD`](c0a50ce33e (diff-5a0d7cff00628c2c64a617edb347c0f283e3a75e7df910e7e8438fc6db23f610R122)) without taking much care with the abi :(
~This is the minimal change to cope with that. Also included in this PR is a temporary bump to 2.2.8 to verify that it builds correctly. I'm happy to revert that and discuss the bump separately, as miniupnpc bumps require some scrutiny.~
I believe that this is problematic if we build against one version and encounter a different one at runtime. This is not a problem for depends because we build statically. But for users who are self-building against shared system libs, care must be taken to run against the same version used for linking.
Some quick digging shows that at least Ubuntu/Arch make the distinction between soversions:
`libminiupnpc.so.17` -> `libminiupnpc.so.18`. So in practice, I suppose this shouldn't be much of a problem.
Boooo for the upstream loose abi policy.
