a6833222ff Move character escaping function to ipautil
Functions `escape_seq` and `unescape_seq` have a generic use-case so it makes
sense to move them from `kerberos` to ipautil module so that other modules can
reuse them more readily.

a6ab515add Allow broadcast ip addresses
Currently environments may use prefix /31 on point-to-point connections what
makes IPA validators to fail. IPA should not care if IP address is broadcast
or not. In some cases (when prefix is not specified) IPA cannot decide
properly if broadcast address is really broadcast.

This commit allows usage of broadcast addresses in:
* host plugin
* dns plugin
* server-installer
* client-installer

5e78b54d7c Fix internal errors in host-add and other commands caused by DNS resolution
Previously resolver was returning CheckedIPAddress objects. This

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

if it needs to be contrained to some subset of IP addresses using

099cf98307 Refactor ipautil.run
The ipautil.run function now returns an object with returncode and
output are accessible as attributes.

The stdout and stderr of all commands are logged (unless skip_output is given).

The stdout/stderr contents must be explicitly requested with a keyword
argument, otherwise they are None.
This is because in Python 3, the output needs to be decoded, and that can
fail if it's not decodable (human-readable) text.

The raw (bytes) output is always available from the result object,
as is "leniently" decoded output suitable for logging.

All calls are changed to reflect this.

A use of Popen in cainstance is changed to ipautil.run.

a758f16abe winsync-migrate: Convert entity names to posix friendly strings
During the migration from winsync replicated users to their
trusted identities, memberships are being preserved. However,
trusted users are external and as such cannot be added as
direct members to the IPA entities. External groups which
encapsulate the migrated users are added as members to those
entities instead.

The name of the external group is generated from the type
of the entity and its name. However, the entity's name can
contain characters which are invalid for use in the group
name.

Adds a helper function to convert a given string to a string
which would be valid for such use and leverages it in the
winsync-migrate tool.

3bf91eab25 Use Python3-compatible dict method names
Python 2 has keys()/values()/items(), which return lists,
iterkeys()/itervalues()/iteritems(), which return iterators,
and viewkeys()/viewvalues()/viewitems() which return views.

Python 3 has only keys()/values()/items(), which return views.
To get iterators, one can use iter() or a for loop/comprehension;
for lists there's the list() constructor.

When iterating through the entire dict, without modifying the dict,
 the difference between Python 2's items() and iteritems() is
negligible, especially on small dicts (the main overhead is
extra memory, not CPU time). In the interest of simpler code,
this patch changes many instances of iteritems() to items(),
iterkeys() to keys() etc.

In other cases, helpers like six.itervalues are used.
