MinGW builds require a thin layer above the standard libraries to
provide POSIX functionality that is missing on Windows. Add support
for building this.
MinGW cross builds are experimental and work is ongoing to integrate
them into the CI and test environment. Including the changes at this
stage is being done to facilitate that process.
The layer has been arranged in the same way as DPDK and is
accessed as an external build using ./configure --with-wpdk=<dir>.
Support has also been added for using a default ./wpdk in
preparation for reaching the required level of stability.
The help text for ./configure indicates that support for --with-wpdk
is experimental.
Further details and instructions can be found at https://wpdk.github.io.
