[GIT net-next] Open vSwitch

[Jesse Gross <jesse@nicira.com>]

A number of improvements for net-next/3.10.

Highlights include:
 * Properly exposing linux/openvswitch.h to userspace after the uapi changes.
 * Simplification of locking. It immediately makes things simpler to reason about and avoids holding RTNL mutex for longer than necessary. In the near future it will also enable tunnel registration and more fine-grained locking.
 * Miscellaneous cleanups and simplifications.

The following changes since commit f498354793d57479d4e1b0f39969acd66737234c:
