Build OVS with dpdk

Builds OVS with DPDK. Uses dpdk 2.2.0 and Open vSwitch 2.5.
Includes Multi-Queue and recent patches.
Open vSwitch RPM is now built with DPDK dataplane.
Upstream copr (Fedora) spec files and patches are used for building.

Also includes fixes of RPM building and command line options.
Adds dpdk arg to RPM test script.

Use "pure" COPR spec files without modifications. Fixed some function problems.
Addressed reviewer comments. Delete local copies of spec files
Build dpdk snapshot instead of using upstream snapshot.
Fix clean script.

"stack" VM with its default configuration doesn't support sse3 instruction set
required by DPDK.  Include workaround to test RPM script in host instead of VM.

Install prereqs for dpdk build.
Use 'set -e' in all scripts for error termination.
Add PyQt4 Pre-req.
Move functions and respond to reviewers comments.
