This commit adds more clarity to handling of TC_CLSMATCHALL_REPLACE and
TC_CLSMATCHALL_DESTROY events by calling newly added *_mall_*() handlers
instead of directly calling SPAN API.

This also extracts matchall rules management out of SPAN API since SPAN
is a hardware module which is used to implement 'matchall egress mirred'
action only.
