Update mini_event.c 
When in heavy load, unbound opens many outside_network sockets for out going queries to delegation servers, which may result in a big fd(maxfd) value(for thread A 65500, for thread B 65501, for thread C ...). 
There are situations when thread A has a max fd num 65500 where maxfd is of course 65500, thread B has max fd num 20 for now but maxfd is still 65501. Though linux kernel checks whether maxfd+1  passed by select syscall  is really the process' maxfd+1. Linux kernel can not tell maxfd+1 passed by thread B select syscall is much bigger(65501+1 or 65500+1  after trimed by kerne) than it should be (20+1).
In this situation, when kernel do_select() for thread B, much work is wasted.

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].
