f90e137a17 Sort and shuffle SRV record by priority and weight
On multiple occasions, SRV query answers were not properly sorted by
priority. Records with same priority weren't randomized and shuffled.
This caused FreeIPA to contact the same remote peer instead of
distributing the load across all available servers.

Two new helper functions now take care of SRV queries. sort_prio_weight()
sorts SRV and URI records. query_srv() combines SRV lookup with
sort_prio_weight().

35ba724de9 Py3: Fix ToASCII method
in Py2 to_text method returns Py2 non-unicode string, but in Py3 to_text method
returns Py3 default (unicode) string. So only in Py2 we have to decode
str to unicode.

5e78b54d7c Fix internal errors in host-add and other commands caused by DNS resolution
Previously resolver was returning CheckedIPAddress objects. This
internal server error in cases where DNS actually returned reserved IP
addresses.

Now the resolver is returning UnsafeIPAddress objects which do syntactic
checks but do not filter IP addresses.

From now on we can decide if some IP address should be accepted as-is or
if it needs to be contrained to some subset of IP addresses using
CheckedIPAddress class.

This regression was caused by changes for

e45a80308c DNS upgrade: change global forwarding policy in LDAP to "only" if private IPs are used
This change is necessary to override automatic empty zone configuration
in latest BIND and bind-dyndb-ldap 9.0+.

This procedure is still not complete because we need to handle global
forwarders in named.conf too (independently on each server).

23507e6124 Alias "unicode" to "str" under Python 3
The six way of doing this is to replace all occurences of "unicode"
with "six.text_type". However, "unicode" is non-ambiguous and
(arguably) easier to read. Also, using it makes the patches smaller,
which should help with backporting.

Additional changes were required for the ipapython.dnsutil.DNSName class,
because it defined both __str__ and __unicode__.
