getting rid of type argument to rte_malloc().

[Stephen Hemminger]

For the 24.11 release, I want to remove the unused type string argument
that shows up in rte_malloc() and related functions, then percolates down
through.  It was a idea in the 1.0 release of DPDK, never implemented and
never removed.  Yes it will cause API breakage, a large sweeping change;
probably easily scripted with coccinelle.

Maybe doing ABI version now?
