I've been evaluating your suggestion and see no downsides,
except contigmem default behavior change, but does it have non-DPDK users?
If no one objects, I'll prepare v3 doing the following:
1) everything from v2,
2) except always mark contigmem buffers as dumpable,
3) add --dump-mapped back and make DPDK disable dumping by default.
As a result, in order to include mapped memory in coredump:
* FreeBSD will require only "--dump-mapped";
* Linux will require both "coredump_filter" setup and "--dump-mapped".
