[PATCH 1/5] build: increase minimum meson version to 0.57

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

In order to work around some deprecated functions in meson, we need to
increase meson version. Increasing to 0.57 to also gain support for
other useful features for us in DPDK. Changes of interest to DPDK
include:

* Use get_external_property instead of get_cross_property
* Ability to use a VERSION file rather than hacking it with scripting
* Ability to set built-in options in cross-build files
* Ability to set pkg_config_libdir in cross-build files
