[v3,00/17] Replace terms master/slave

  As announced in 20.08 release notes, the terms for lcore role
will change in 20.11 release.

This is a project wide patchset to terminolgy used for DPDK lcore.
The term "master" referring to lcore is replaced with "main" and
"slave" lcore is replaced with "worker" lcore.

This is most visible in API for rte_get_master_lcore() which is
replaced with rte_get_main_lcore(). And the macros for iterating
over lcores are replaced as well.

The first patch introduces a way to mark macro's as deprecated
as well.

Note: this patch will fail checkpatch because current versions
of checkpatch flag use of master/slave as an error. Also,
until the whole patch series is applied, the build will generate
non-fatal warnings.

v3
   - incorporate still more places where master/slave was still used

v2
   - fix more places found by Anatoly and grep
   - add coding style update
   - add memif changes
