was reworded.

Wrap printing exceptions in unicode() to do Gettext conversion.

pkisilent does not handle these properly.

IPA has some unused code from abandoned features (Radius, ipa 1.x user
input, commant-line tab completion), as well as some duplicate utilities.
This patch cleans up the utility modules.

Duplicate code consolidated into ipapython.ipautil:
    {ipalib.util,ipaserver.ipautil,ipapython.ipautil}.realm_to_suffix
    {ipaserver,ipapython}.ipautil.CIDict
            (with style improvements from the ipaserver version)
    {ipapython.entity,ipaserver.ipautil}.utf8_encode_value
    {ipapython.entity,ipaserver.ipautil}.utf8_encode_values

ipalib.util.get_fqdn was removed in favor of the same function in
ipaserver.install.installutils

Removed unused code:
    ipalib.util:
        load_plugins_in_dir
        import_plugins_subpackage
        make_repr (was imported but unused; also removed from tests)

    ipapython.ipautil:
        format_list
        parse_key_value_pairs
        read_pairs_file
        read_items_file
        user_input_plain
        AttributeValueCompleter
        ItemCompleter

    ipaserver.ipautil:
        get_gsserror (a different version exists in ipapython.ipautil)

ipaserver.ipautil ended up empty and is removed entirely.

Global DNS configuration is a nice tool to maintain a common DNS
settings stored in LDAP which are then used for all enrolled IPA
servers. However, the settings stored in LDAP override local
settings in named.conf on DNS servers.

This patch adds more information about global DNS configuration
options in install scripts and DNS module help.

Server framework calls acutil.res_send() to send DNS queries used
for various DNS tests. However, once acutil is imported it does
not change its list of configured resolvers even when
/etc/resolv.conf is changed. This may lead to unexpected
resolution issues.

We should at least reload httpd when we change /etc/resolv.conf to
point to FreeIPA nameserver to force a new import of acutil and
thus workaround this bug until it is resolved in authconfig.

We don't want to run the risk of adding a user, uninstalling it,
the system adding a new user (for another package install for example)
and then re-installing IPA. This wreaks havoc with file and directory
ownership.

Admin e-mail validator currently requires an email to be in
a second-level domain (hostmaster@example.com). This is too
restrictive. Top level domain e-mails (hostmaster@testrelm)
should also be allowed.

This patch also fixes default zonemgr value in help texts and man
pages.

https://fedorahosted.org/freeipa/ticket/2272

Add support for autobind to services. This is a bit of a special case
so I currently require the caller to specify ldapi separately. It only
makes sense to do this only in upgrade cases.

Also uninstall ipa_memcached when uninstalling the server.

For ssh, VerifyHostKeyDNS option is set to 'yes' if --ssh-trust-dns
ipa-client-install option is used.

For sshd, KerberosAuthentication, GSSAPIAuthentication and UsePAM
options are enabled (this can be disabled using --no-sshd
ipa-client-install option).
