Our configure script does not enable -Werror on macOS and FreeBSD
by default yet. That's bad in the CI, since we might miss compiler
warnings and thus bugs this way. So after fixing a problem in the
configure script in the first patch, we now turn on -Werror here
in the second and third patch. The fourth patch is just a cosmetical
one, since Cirrus-CI seems to upgrade all jobs automatically to
Cataline these days.

v2:
 - Split the -Werror enablement patch into two, one for FreeBSD and
   one for macOS
 - Use -Wno-error=deprecated-declarations instead of --disable-sasl
   on macOS to work-around the deprecation messages from Apple.

Thomas Huth (4):
  configure: Fix atomic64 test for --enable-werror on macOS
  cirrus.yml: Compile FreeBSD with -Werror
  cirrus.yml: Compile macOS with -Werror
  cirrus.yml: Update the macOS jobs to Catalina
