Release 2.11.0

A couple of new features this release courtesy of Petr Špaček @pspacek (ISC) and a bunch of bugfixes.

Packages are available at: https://dev.dns-oarc.net/packages/

First off dnsperf can now do verbose statistics during each interval when using -S, see long option verbose-interval-stats.

Next is a new latency histogram output using data structures (hg64) created by Tony Finch @fanf2 (ISC), see long option latency-histogram. These will also be shown during -S when used together with verbose-interval-stats.

Lastly a small change to boolean long options, they no longer require a value (=yes) to be enabled.

Bugfixes:

• Make sure the number of outstanding queries don't go negative, happens if queries are timed out before being sent
• Fixed #208:
  • recv_one(): Fix handling errno, only store EAGAIN if no other error has been received
  • do_recv(): Don't break on error as it will count it as a received message
  • Treat EBADF as EAGAIN for stateful connections, receive thread might read from a closed socket if send thread is reconnecting
• dnsperf: warn if -c, -T, -q, -Q values are auto-adjusted
• Fixed #222: don't process unexpected message if the message is suppressed
