To allow support for additional build checks and tests only really relevant for developers, we add support for a developer mode option to DPDK. The default, "auto", value for this enables developer mode if a ".git" folder is found at the root of the source tree - as was the case with the previous "make" build system. There is also support for explicitly enabling or disabling this option using "meson configure" if so desired. Signed-off-by: Bruce Richardson <bruce.richardson@intel.com>
