Implement first, unfinished version of DNS support and fix incomplete TCP stream bug

Browse source 
This commit does two things:
First, it implements a first, unfinished version of the virtual DNS
functionality. This feature is incomplete and has known bugs. Since it
needs to be enabled manually, this is not a huge issue so far.
Second, the commit fixes a bug where TCP streams where not properly
relayed, causing TCP connections to stall.
