Normally, in C code, pre-processing macros can be used to enable/disable specific functionality based on switches passed to configure. This works for DPDK using the --with-dpdk flag, which sets the DPDK_NETDEV define to the appropriate value.
However, not all files are processed with the C pre-processor. For those files which are not, this commit adds a new pre-processor tool for .in files to either include or exclude those stanzas as appropriate.
