* Add another maintainer to libzmq's CC list
* Enable UBSAN for libzmq
* libzmq: disable afl fuzzer, CI fails
* libsodium: do not let libsodium's autogen.sh download files from gnu.org
There is no sanity check and if the download fails because gnu.org is down
the build fails with unhelpful errors
* libzmq: add alternative mail address and other maintainer's address
* libzmq: adjust zmq_z85_decode test
The output buffer is not fixed in size, it depends on input size and the
caller allocates it
* libzmq: add tests for handshake engine on connect/bind
Create localhost ipv4 TCP sockets to exercise libzmq's processing
of data over the network.
This connections should be rejected in the first part of the handshake
(greeting) only, so more tests should be added to further mock the
greeting and exercise deeper parts of the engine.

* libzmq: fix coverage build
The combination of clang, coverage and automake is not happy at the
moment, and binaries fail to link. We don't need to build any of
the tools for these tests, so simply disable them.
