Complete StreamStack and add tests.

TLSLayer could not be updated because it requires TLS to be ported first. Updates other classes, only for having compatibility with SafeByteArray because of updates in Stream Stack. License: This patch is BSD-licensed, see Documentation/Licenses/BSD-simplified.txt for details. Test-Information: Tests added for StreamStack and XMPPLayer, which passes.
