This commits adds the multithreading functionality to OVS dpdk
module. Users are able to create multiple pmd threads and set
their cpu affinity via specifying the cpu mask string similar
to the EAL '-c COREMASK' option.
Also, the number of rx queues for each dpdk interface is made
configurable to help distribution of rx packets among multiple
pmd threads.

In the flow related functions, there's a stack variable called
'linux_flow'. Since this code is not specific to Linux anymore,
in this patch, we rename the variable to 'datpath_flow'.

The patch contains the necessary modifications to compile and also to run
under MSVC.
Added the files to the build system and also changed dpif_linux to be under
a more generic name dpif_windows.
Added a TODO under the windows part in case we want to implement another
counterpart for epoll functions.
