a1d91d2a3d tap-vsockd: support daemonization via a --daemon arg 
We daemonize after checking the command-line and binding/connecting
the socket and creating the tap device. Only the ethernet frame
processing happens afterwards.

This patch also includes a new well-known service GUID for the
VPN-proxy ethernet service.

f636321b81 tap-vsockd: support both connect() and accept() 
Older versions of the Linux AF_HVSOCK can only accept() as they
don't allow connections to the parent partition. Support both
modes for now.

61b38236a9 kernel: cherry-pick more VMBus patches, fix for yet another kernel crash 
These are most of the changes to channel.c and channel_mgmt.c from upstream.

They are needed to apply a proposed patch to fix yet another kernel crash
we reported. This patch is also included.

With these patches applied many thousand connections with random data and up
to 10 concurrent connections are sustained without kernel crashes.

This patch also updates the core Hyper-V socket support to v11 (which
also obsoletes the previous patch added to work around a kernel bug)

58b500ccd9 kernel: Fix Null pointer de-reference in af_hvsock code 
The Hyper-V socket patch has a bug which was triggered by a race condition when
the client connected and then immediately closed the connection before the
server would call accept(). This caused a kernel crash.

This patch was discussed with Dexuan Cui <decui@microsoft.com>, the original
author of the Hyper-V socket support.
