net/mld: Add basic build structure for Multicast Listener Discovery (MLD). No real MLD logic yet. Only a few hooks to capture and dispatch MLD ICMPv6 packets.

Add new configuratin CONFIG_NET_MCASTGROUP. This option is selected automatically if either CONFIG_NET_IGMP or CONFIG_NET_MLD are selected. Most conditional logic based on CONFIG_NET_IGMP replaced with conditioning on CONFIG_NET_MCASTGROUP.

Squashed commit of the following: include/nuttx/net/ipv6ext.h: Fix some terminology: Hop-by-hop, not Hop-to-hop or Hop2hop. net/devif/ipv6_input.c and net/icmpv6/icmpv6_input.c: Add logic to skiip over the variable number of IPv6 extension headers that may be present between the IPv6 header and the transport layer header. The extension headers are simply ignored. This is necessary because with MLD, certain incoming messages may have, at a mimimum, a Router Alert Hop-by-hop extension header. net/inet/ipv6_setsockopt.c: Implement the IPV6_JOIN_GROUP and IPV6_LEAVE_GROUP socket options.

net/mld: Add reference counting on the group joins. If there are multiple joins from the same group on this, the don't really leave the group until the matching number of leaves happen. Also add to hooks for the router case: Keep track of the number members NOT on this host. Integrate this with the Leave logic to that the group structure can persist while there no non-local members of the group as well.

future. Use IPv6 multicast routers to discover the presence of multicast
listeners (nodes configured to receive IPv6 multicast packets)
on its directly attached links and to discover which multicast packets
are of interest to neighboring nodes. All IPv6 multicast routers that
run MLD on the same subnet can monitor MLD listener report messages
(often called reports) from hosts. However, only one router can act as
the MLD querier to send MLD query messages (often called queries).
A querier election mechanism determines which router acts as the MLD
querier on the subnet.

net/mld: Standard usage of debug output macros. Add configuration options to enable MLD debug even when there network debug is disabled. Add configuration option to dump the content of outgoing MLD packets.

---help---
Normally, MLD debug output is controlled by CONFIG_DEBUG_NET_*.
This option will force debug output from MLD files even if network
debug is not enabled. This feature does still depend on global
debug output CONFIG_DEBUG_INFO, CONFIG_DEBUG_WARN, and
CONFIG_DEBUG_ERROR.
config NET_MLD_TXDUMP
bool "Enable TX Packet Dump"

---help---
Dump the content of all outgoing packets.
