<li> allow multiple IPv4 addresses to be assigned to an interface (bug 188).

<li> Add class Ipv4InterfaceAddress:
This is a new class to resemble Linux's struct in_ifaddr. It holds IP addressing information, including mask,
broadcast address, scope, whether primary or secondary, etc.

<li> At the helper API level, one often gets an address from an interface
container. We preserve the legacy GetAddress (uint32_t i) but it
is documented that this will return only the first (address index 0)
address on the interface, if there are multiple such addresses.
We provide also an overloaded variant for the multi-address case:
