[dpdk-dev] [RFC 3/6] devtools: add abi dump generation script

[Kevin Laatz <kevin.laatz@intel.com>]

This patch adds a script to generate ABI dump files. These files will be
required to perform ABI compatibility checks during the build later in the
patchset. This script should be run on a DPDK version with a stable ABI.

Since this is a tool designed for human use, we simplify it to just work
off a whole build directory, taking the parameter of the builddir and
generating the lib|drivers/abi dir. This is hardcoded into the script since
the meson build expects the .dump files in these directories.
