Try to use the URI /ipa/session/xml if there is a key in the kernel
keyring. If there is no cookie or it turns out to be invalid (expired,
whatever) then use the standard URI /ipa/xml. This in turn will create
a session that the user can then use later.

IPA server web form-based authentication allows logins for users
which for some reason cannot use Kerberos authentication. However,
when a password for such users expires, they are unable change the
password via web interface.

This patch adds a new WSGI script attached to URL
/ipa/session/change_password which can be accessed without
authentication and which provides password change capability
for web services.

The actual password change in the script is processed by LDAP
password change command.

Password result is passed both in the resulting HTML page, but
also in HTTP headers for easier parsing in web services:
  X-IPA-Pwchange-Result: {ok, invalid-password, policy-error, error}
  (optional) X-IPA-Pwchange-Policy-Error: $policy_error_text

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.

Move the code for encoding boolean values to LDAP boolean syntax from the
Parameter class to the Encoder class, where the rest of LDAP encoding takes
place. Remove encoding code from the Parameter class altogether, as all LDAP
encoding should be done in the Encoder class.

This reverts commit a58cbb985ec007c0ef83010b32408efb2f4784d2.

We are going to take another approach to this. Instead of erroring
out on attributes that don't seem to be allowed we are going to
eventually return a warning.

ldap2 plugin returns NotFound error for find_entries/get_entry
queries when the server did not manage to return an entry
due to time limits. This may be confusing for user when the
entry he searches actually exists.

This patch fixes the behavior in ldap2 plugin to
1) Return even a zero search results + truncated bool set in
   ldap2.find_entries
2) Raise LimitsExceeded in ldap2.get_entry and
   ldap2.find_entry_by_attr instead of NotFound error

This changed several assumptions about ldap2.find_entries
results. Several calls accross IPA code base had to be
amended.

Replace all occurences of create_default with equivalent default_from
and remove create_default from the framework. This is needed for
proper parameter validation, as there is no way to tell which
parameters to validate prior to calling create_default, because
create_default does not provide information about which parameters are
used for generating the default value.

The new version of python-ldap changed the way it created LDAPv3
extended controls. The API used in 2.4.x can no longer be used
because it does not send the bind DN with effective rights
control and LDAP server thus rejects it.

This patch implements the new API in a backward compatible way
so that it works both with python-ldap versions 2.3.x and 2.4.x.

get_allowed_attributes function was improved to look for allowed
attributes also in the superior objectclasses of specified objectclass.

This fixes the regression caused by patch for ticket #2293. Test-case
for unit-test was also created.
