MDL-47990 qtype_multichoice: fix test response import/export
MDL-48026 output: action_menu no wrap improvement

Action menu output component has a new method set_nowrap_on_items
that sets a property to toggle nowrap on menu items.
That can be used to avoid problems when the menu appears within
an absolutely positioned or floated element.

MDL-43430 enrol_ldap: Enrolment lost if member of group with parenthesis

As part of fixing MDL-43430, a typo has been detected in the
quoted alphanumeric characters (the '=' and '>' were transposed).
MDL-43430 enrol_ldap: Enrolment lost if member of group with parenthesis

The group names we get from ldap_find_user_groups() can contain invalid LDAP
filter characters. So we need to escape them for LDAP filter usage.
MDL-43430 enrol_ldap: Enrolment lost if member of group with parenthesis

While testing the fix, it was found that ldap_stripslashes() was broken and
using a deprecated PCRE patter modifier, so it's also been fixed.

Thanks to Damyon Wiese, some units tests have been added to cover
ldap_addslashes() and ldap_stripslashes().
