[dpdk-dev] [PATCH] scripts: support any legal git revisions as abi validation range

[Panu Matilainen <pmatilai@redhat.com>]

In addition to git tags, support validating abi between any legal
gitrevisions(7) syntaxes, such as "validate-abi.sh . -1 <target>"
"validate-abi.sh master mybrach <target>" etc in addition to
validating between tags. Makes it easier to run the validator
for in-development work.
