[dpdk-dev] [PATCH v3 1/4] build: add single source of DPDK version number

[Bruce Richardson <bruce.richardson@intel.com>]

Add a new file VERSION to hold the current DPDK version number.
Have meson use this file for it's project version, and have make use
it for reporting out "showversion" and "showversionum".

v3: rename file from DPDK_VERSION to VERSION
v2: fix typos and include Luca's ack.
