[Bug 1945810] [NEW] libfido2: Fail to build against OpenSSL 3.0

[Simon Chopin]

Public bug reported:

Hello,

As part of a rebuild against OpenSSL3, this package failed to build on one or
several architectures. You can find the details of the rebuild at 

https://people.canonical.com/~schopin/rebuilds/openssl-3.0.0-impish.html

or for the amd64 failed build, directly at

https://launchpad.net/~schopin/+archive/ubuntu/openssl-3.0.0/+build/22098609/+files/buildlog_ubuntu-
impish-amd64.libfido2_1.6.0-2.0~ssl3ppa1.1_BUILDING.txt.gz

We're planning to transition to OpenSSL 3.0 for the 22.04 release, and consider
this issue as blocking for this transition.

You can find general migration informations at
https://www.openssl.org/docs/manmaster/man7/migration_guide.html
For your tests, you can build against libssl-dev as found in the PPA
schopin/openssl-3.0.0

There are quite a few commits in the upstream master dealing with the OpenSSL 3.0
compatibility, the list is there:
https://github.com/Yubico/libfido2/search?q=openssl+3&type=commits

Looking at both the commit logs and the build log, we could probably
just add -Wno-error=deprecated-declarations -Wno-error=discarded-
qualifiers as a workaround.

** Affects: libfido2 (Ubuntu)
     Importance: Undecided
         Status: New
