[dnscap-users] DNSCAP release 1.4.0

[Jerry Lundström]

Greetings all,

Until it can be confirmed that the threaded code works as well as the
non-threaded code it has been made optional and requires a configuration
option to enable it during compilation.

New extended option:
- `-o pcap_buffer_size=<bytes>` can be used to increase the capture
  buffer within pcap-thread/libpcap, this can help mitigate dropped
  packets by the kernel during breaks (like when closing dump file).

Packages are available at:
