libwrap support needs to be added to Meson
We support TCP Wrappers (libwrap) only with Autotools and not with Meson. As we're going to drop Autotools, we'll either have to add libwrap support to Meson or drop the libwrap stuff entirely. Debian seems to build PulseAudio with libwrap, Fedora doesn't. Arch has already moved to Meson, so they naturally don't build PulseAudio with libwrap either.
I think we should add libwrap support to Meson, because dropping features is bad. As far as I can tell, libwrap isn't obsolete even if the TCP Wrapper functionality isn't widely used with PulseAudio.
