Start experimenting with better support for captive portals
...
MacOS (and probably Windows and other systems) tries to fetch a URL
before marking a network interface as available.
During this time, applications cannot use the interface at all, not
even bind their address.
When DNS queries are sent to dnscrypt-proxy, this causes the system
to wait for a response that can't come from the network, since we
hit a dead lock here.
The only option is to return hard-coded responses directly until
te interface is available.
The same captive portal configuration file can also serve a different
purpose.
Once the network is available, captive portal detection may not
work as expected if the answer is cached for too long. In fact, it
probably can't work at all since routers can't hijack DNS queries.
Once thing we can do is redirect the list of names used for captive
portal detection to the fallback resolvers. This may allow detection
to work as expected while still using a secure channel for all
other queries.

Remove LargerResponsesDropped
...
dnsdist drops DNSCrypt queries shorter than 256 bytes, interpreting them
as not being encrypted instead. This is surprising when doing ad-hoc
testing, but absolutely fine, and we will never send shorter encrypted
queries on normal circumstances.
So, remove a useless knob.

...
A 128 bytes query will not get a 200 bytes response (randomly tested on
3.tlu.dl.delivery.mp.microsoft.com), not even a truncated one.
It may be related to fragments being blocked on the server socket, or a
different issue. We can expect everything to be back to normal in dnsdist
1.5.0 no matter what.
