- Merge PR #173: updated makedist.sh for config.guess and
config.sub and sha256 digest for gpg, by noloader.
- Merge PR #164: Framestreams, this branch implements dnstap
unidirectional connectivity in unbound. This has a number of
new features.

The dependency on libfstrm is removed. The fstrm protocol code
resides in dnstap/dnstap_fstrm.h and dnstap/dnstap_fstrm.c. This
contains a brief definition of what unbound needs.

The make unbound-dnstap-socket builds a debug tool,
unbound-dnstap-socket. It can listen, accept multiple DNSTAP
streams and print information. Commandline options control it.

Unbound can reconnect if the unix domain socket file socket is
closed. This uses exponential backoff after which it uses a
one second timer to throttle cpu down. There is also support
to use TCP and TLS for connecting to the log server. There
are new config options to turn them on, in the dnstap section
in the man page and example config file. dnstap-ip with IP
address of server for TCP or TLS use. dnstap-tls to turn
on TLS. And dnstap-tls-server-name, dnstap-tls-cert-bundle,
dnstap-tls-client-key-file and dnstap-tls-client-cert-file
to configure the certificates for server authentication and
client authentication, or leave at "" to not use that.

- Fix #29: Solaris 11.3 and missing symbols be64toh, htobe64.
- Fix #30: AddressSanitizer finding in lookup3.c. This sets the
hash function to use a slower but better auditable code that does

but not read outside of the array.
