When re-running `ipa-server-install --setup-dns` on already installed
server, we do not get to the check of being already installed because
DNS zone overlap forces us to fail earlier.
Change exception returned for this case from check_zone_overlap() to
return structured information that allows to understand whether we are
finding a conflict with ourselves.
Use the returned information to only fail DNS check at this point if DNS
zone overlap is generated by a different name server than ourselves.

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().

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 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).

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.

Rename __unicode__ to __str__ in classes which define it and use the
six.python_2_unicode_compatible decorator on them to make them compatible with
both Python 2 and 3.
Additional changes were required for the ipapython.dnsutil.DNSName class,
because it defined both __str__ and __unicode__.
