Make it possible to specify multiple ConsensusParams torrc
lines.

Now directory authority operators can for example put the
main ConsensusParams config in one torrc file and then add to it
from a different torrc file.

If at least one service is configured as a version 2, a log warning is emitted
once and only once.

First, we introduce a flag to teach src/test/test to split its work
into chunks.  Then we replace our invocation of src/test/test in our
"make check" target with a set of 8 scripts that invoke the first
8th of the tests, the second 8th, and so on.

This change makes our "make -kj4 check" target in our hardened
gitlab build more than twice as fast, since src/test/test was taking
the longest to finish.

Fixes #40135

The option `--enable-all-bugs-are-fatal` when used with
`--disable-module-relay` caused GCC to warn about functions that
it thought should be labeled noreturn.

I've tried a couple of approaches, but disabling the warning on
these functions seems to be the best approach.

Fixed #40129; bugfix on 0.4.4.1-alpha.
