Comment:

 I moved the libdhcp++ logic which handles socket operations to a separate
 class. The unit tests use a customized class to mimic socket operations on
 the fake interfaces. With this approach, the IfaceMgr::openSockets6 logic
 can be unit tested without trying to open any actual sockets.

 Proposed !ChangeLog:
 {{{
 XXX.    [bug]           marcin
         libdhcp++: Implemented unit tests for the IfaceMgr's routine which
 opens
         IPv6 sockets on detected interfaces. The IfaceMgr logic performing
 low
         level operations on sockets has been moved to a separate class. By
         providing a custom implementation of this class, the unit tests
 may
         use fake interfaces with custom configuration and thus cover wide
         range of test scenarios for the function.
         (Trac #3251, git abc)
