Merge of branches/team/network/new_stack - not yet complete as SVN does only support
replacing files when merging when you don't have deleted them manually (for some reason, it only works as part of the merge operation, and we didn't copy the whole tree to have "a fresh start" - next time we know better, at least if SVN still suffers from that same limitation). git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@18456 a95241bf-73f2-0310-859d-f6bbb57e9c96
