0784ad7a11 #420 
clear the c->buffer in the comm_point_send_reply does resolve the "can't fit qbuffer in c->buffer" issue, but it breaks the mesh reply list function that need to reuse the answer. because the c->buffer is cleared in the comm_point_send_reply, it cannot be resued again. it means that it is not inappropriate to clear c->buffer in the comm_point_send_reply.

After some investigation, i found it is appropriate to clear c->buffer before use in the http2_query_read_done.

Update netevent.c 
#386
I found the root cause of this issue. r_buffer is r->query_reply.c->buffer, used to fill the reply in the mesh_send_reply function, then call comm_point_send_reply, and then call http2_submit_dns_response to send the DOH response. However, the buffer is not cleared after use. If the query length is greater than the last response length, the next dns query in the same H2 session will encounter an error.
This is bug!!!

Clear the buffer after use.

422213c171 add missing null check 
I have a unbound forward zone configured on my router for my $DAYJOB.
The address associated with the zone is only accessible when the router
is connected to a VPN. If the VPN connection is absent, trying to
resolve any domain that must be handled by the zone crashes unbound.
Turns out there's a missing NULL check in `comm_point_send_udp_msg()`.
The same routine already has `if (addr) {} else {}` branches so I guess
protecting the call to `log_addr()` using the same conditional is
reasonable

I have also committed the same fix to unbound shipped with OpenBSD[1].
