Michael Bushkov a59d6a8724 Implementing 'fallback' nsswitch source. 'fallback' source is used
when particular function can't be found in nsswitch-module. For
example, getgrouplist(3) will use module-supplied 'getgroupmembership'
function (which can work in an optimal way for such source as LDAP) and
will fall back to the stanard iterate-through-all-groups implementation
otherwise.
