This commit is to correct the order in which the fields are
accessed while verifying it. First the fields should be
verified, and if it is valid then access it.

Issue: When an IGMPv2 leave packet is received, it did not validate
the checksum and hence the packet is accepted and group specific
query is sent out in response to this.
Due to this IGMP conformance test case 6.1 failed.

Fix: Validate the checksum for all IGMP packets

Fix details :
Added a utility cli to generate a igmp query on an interface.
This won't impact the existing query generation based on the
general query interval.

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

When we receive a group in a IGMP report
let's look it up based upon a hash
instead of a list.

When a toin IGMPv3 join is received, the code
was always auto creating the igmp group associated
with the received packet. The RFC clearly states
though that if a INCLUDE is received for a group
with 0 sources and we have received nothing the
igmpv3 packet should be ignored.

We were passing in the interface name when we were also
passing in the igmp pointer which has this information.
