Make Networks equivalent with Swiften.
Adds ProxyProviders, DomainNameResolvers and DummyConnection. License: This patch is BSD-licensed, see Documentation/Licenses/BSD-simplified.txt for details. Test-Information: Tests added for ChainedConnector, Connector and HostAddress. Test also added for ComponentConnector, which needed bits of Network. Five assertions are commented in ConnectorTest, which fails and will be updated after review. Change-Id: I8a62841eb2f9c109bc3a94865b7a003b33493e11
