Subject: ipmr: ip6mr: Create new sockopt to clear mfc cache only

Created a way to clear the multicast forwarding cache on a socket
without having to either remove the entries manually using the delete
entry socket option or destroy and recreate the multicast socket.

Using the flags MRT_FLUSH_ENTRIES and MRT_FLUSH_VIFS, all multicast
entries can be cleared, all multicast interfaces can be closed or both
can be cleared using one sockopt call.

Patch Set 2:
  - Fix Compile Errors

Patch Set 3:
  - Fix Style Errors

Patch Set 4:
  - Implemented a way to clear the entries or vifs based off an input flag.
