IPA client and server tool set used authconfig acutil module to
for client DNS operations. This is not optimal DNS interface for
several reasons:
- does not provide native Python object oriented interface
but but rather C-like interface based on functions and
structures which is not easy to use and extend
- acutil is not meant to be used by third parties besides
authconfig and thus can break without notice
Replace the acutil with python-dns package which has a feature rich
interface for dealing with all different aspects of DNS including
DNSSEC. The main target of this patch is to replace all uses of
acutil DNS library with a use python-dns. In most cases, even
though the larger parts of the code are changed, the actual
functionality is changed only in the following cases:
- redundant DNS checks were removed from verify_fqdn function
in installutils to make the whole DNS check simpler and
less error-prone. Logging was improves for the remaining
checks
- improved logging for ipa-client-install DNS discovery

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.

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.

A server may have 2 or more NICs and its hostname may thus resolve
to 2 and more forward addresses. IP address checks in install
scripts does not expect this setup and may fail or crash.
This script adds a support for multiple forward addresses for
a hostname. The install scripts do not crash now. When one IP
address is needed, user is asked to choose from all detected
server IP addresses.

change default_logger_level to debug in configure_standard_logging
add new ipa_log_manager module, move log_mgr there, also export
root_logger from log_mgr.
change all log_manager imports to ipa_log_manager and change
log_manager.root_logger to root_logger.
add missing import for parse_log_level()
Do at least a basic validation of DNS zone manager mail address.
Do not require '@' to be in the mail address as the SOA record
stores this value without it and people may be used to configure
it that way. '@' is always removed by the installer/dns plugin before
the DNS zone is created.

When getpass.getpass() function is interrupted via CTRL+D, EOFError
exception is thrown. Most of the install tools are not prepared for
this event and crash with this exception. Make sure that it is
handled properly and nice error message is printed.

Integrate new bind-dyndb-ldap features to automatically track
DNS data changes:
1) Zone refresh
Set --zone-refresh in installation to define number of seconds
between bind-dyndb-ldap polls for new DNS zones. User now
doesn't have to restart name server when a new zone is added.
2) New zone notifications
Use LDAP persistent search mechanism to immediately get
notification when any new DNS zone is added. Use --zone-notif
install option to enable. This option is mutually exclusive
with Zone refresh.
To enable this functionality in existing IPA installations,
update a list of arguments for bind-dyndb-ldap in /etc/named.conf.
An example when zone refresh is disabled and DNS data change
notifications (argument psearch of bind-dyndb-ldap) are enabled:
dynamic-db "ipa" {
...
arg "zone_refresh 0";
arg "psearch yes";
};
This patch requires bind-dyndb-ldap-1.0.0-0.1.b1 or later.

When DNS plugin is installed via ipa-dns-install and user has a valid
Kerberos ticket at the time, the DNS installation is corrupt and named
won't start, reporting Preauthentication error.
When the non-DM identity is used for authentication, krbprincipalkey
attribute in DNS service LDAP record is not created, thus leading
to the error. This patch makes sure that authentication with Directory
Manager password is used every time.

Create reverse DNS zone for /24 IPv4 subnet and /64 IPv6 subnet by
default instead of using the netmask from the --ip-address option.
Custom reverse DNS zone can be specified using new --reverse-zone
option, which replaces the old --ip-address netmask way of creating
reverse zones.
The reverse DNS zone name is printed to the user during the install.
ticket 1398
Implements a way to pass match_local and parse_netmask parameters
to IP option checker.
Now, there is just one common option type "ip" with new optional
attributes "ip_local" and "ip_netmask" which can be used to
pass IP address validation parameters.
https://fedorahosted.org/freeipa/ticket/1333
--no-host-dns option should allow installing IPA server on a host
without a DNS resolvable name.
Update parse_ip_address and verify_ip_address functions has been
changed not to return None and print error messages in case of
an error, but rather let the Exception be handled by the calling
routine.

When a new reverse zone was created in ipa-replica-prepare (this
may happen when a new replica is from different subnet), the master
DNS address was corrupted by invalid A/AAAA record. This caused
problems for example in installing replica.

The changes include:
* Change license blobs in source files to mention GPLv3+ not GPLv2 only
* Add GPLv3+ license text
* Package COPYING not LICENSE as the license blobs (even the old ones)
mention COPYING specifically, it is also more common, I think
https://fedorahosted.org/freeipa/ticket/239
Notable changes include:
* parse AAAA records in dnsclient
* also ask for AAAA records when verifying FQDN
* do not use functions that are not IPv6 aware - notably socket.gethostbyname()
The complete list of functions was taken from http://www.akkadia.org/drepper/userapi-ipv6.html
section "Interface Checklist"
Uses a new subclass IPAOptionParser in scripts instead of OptionParser
from the standard python library. IPAOptionParser uses its own IPAOption
class to store options, which adds a new 'sensitive' attribute.
