[RFC PATCH v1 4/5] eal: rename --socket-mem/--socket-limit

[Anatoly Burakov <anatoly.burakov@intel.com>]

Currently, --socket-mem and --socket-limit EAL flags effectively refer to
NUMA nodes, not CPU sockets. Update the flag names to reflect this. Old
flag names are still supported for backward compatibility.

Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>

Notes:
    Technically, this is a user-facing change and so would require a
    deprecation notice. We can do it the other way around, and add
    support for --numa-mem/--numa-limit but do not expose it in
    documentation yet, and instead add a deprecation notice for next
    release. However, since old flags are kept for compatibility,
    nothing will break as a result of merging this series even if we
    didn't announce this change in advance. I'm open to feedback on
    how to best do this change.
