  While meson has standardized the names and macros used for the libraries
and drivers in DPDK, the old macros used from the make system were not
previously announced as deprecated. Therefore to ensure compatibility of
apps being rebuilt, we add these defines back in when appropriate.

Fixes: 5b9656b157d3 ("lib: build with meson")
Fixes: 9314afb68a53 ("drivers: add infrastructure for meson build")

+* build: A number of macros, which defined what DPDK components were being

+  scheme for the relevant library template or driver class template. These
+  deprecated macros can be found in the file
+  ``config/rte_compatibility_defines.h``, listed in the format ``#ifdef

   DPDK will be increased to v0.47.1 (from 0.41) from DPDK 19.05 onwards. For
