net/ipforward: Check if interface is up early on when forwarding to avoid extra work.
As noticed in a previous wireless commit, when forwarding is enabled and a packet comes in, the packet is attempted to be sent on each other netdev without regard for whether it is in the UP state. Of course this is eventually caught, but it can be caught earlier to avoid unnecessary work, especially in the 6LoWPAN case where a useless packet conversion will occur.

net/udp: Remove net stack dependency from CONFIG_NET_BROADCAST

net/: Fix some naming inconsistencies, Fix final compilation issies.
net/inet/inet_close(): Now that we have logic to drain the buffered TX data, we can implement a proper lingering close.
net/inet,tcp,udp: Add functions to wait for write buffers to drain.
net/udp: Add support for notification when the UDP write buffer becomes empty.
net/tcp: Add support for notification when the TCP write buffer becomes empty.
net/inet: Fix tcp active close in inet_close.c
In previous implementation, FIN packet was not sent when a socket
is actively closed (e.g. telnetd or webserver) without SO_LINGER.
This issue happens because the socket closing sequence waits for
the status.cl_sem only if lingering timeout is set. However,
in many server use-cases, SO_LINGER is not usually set and even
in these cases, FIN packet must be sent correctly.
This PR changes the logic in inet_close.c so that it can wait
for status.cl_sem regardless of SO_LINGER. Instead, if SO_LINGER
is set, it waits for the semaphore with timeout option.

net/usrsock: Fix debug logs and remove DEBUGASSERT from usrsockdev_do_request()
In a client mode, socket() will be the first request for usrsockdev_do_request().
However, in a server mode, the first request to accepted sockets will be recv()
or others which depend on applications. So I think we should remove this
DEBUGASSERT from usrsockdev_do_request().

The MLD implementation did not follow the RFC correctly when it is the Querier. The Querier should use a general query and get query messages from all members of all groups. This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.
Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.

net/icmpv6/icmpv6_input.c: Correct caculation of the ICMPv6 header address

net/mld/mld_report.c: Fix host vs. network order problem.
net/mld/mld_send.c: Correct the address used in sending the General Query. It should be the unspecified address in that case.
net/mld: Querying workaround. The MLD implementation does not follow the RFC correct when it is the Querier. The Querier should use a general query and get query messages from all members of all groups. This would be driven by a single timer since all groups are queried at once. Instead, the design currently uses a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.
Normally it is required that the network be in the "down" state when re-configuring the network interface. This is thought not to be a necessary here because.
1. The ICMPv6 logic here runs with the network locked so there can be no outgoing packets with bad source IP addresses from any asynchronous network activity using the device being reconfigured.
2. Incoming packets depend only upon the MAC filtering. Network drivers do not use the IP address; they filter incoming packets using only the MAC address which is not being changed here.
net/mld: Fix a couple of places where I forgot to unlock the network in the previous commit.
net/mld: Implement 'Other Querier Present Timer'. This timer is used to revert to Querier mode if there is no other querier on the network. Also, fix some naming: The Done message is not just Version 1 but is used with Version 2 as well.
net/igmp: Back out some blind, backported improvements to IGMP from MLD. There are too many subtle differences in the protocols for this to be safe.
net/mld: Checksum calculation needs to know the full size of the IPv6 header, including the size of the extension headers. The payload size in the IPv64 header must include the extension headers (not considered part of the header in this case). Fixes a few additional errors in size, endian-ness and checksum calculations. Wireshark now reports the the outgoing Report has a good checksum.
net/mld/mld_query.c: Add a cast to assure that the left shift does not overflow.

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: The MLD logic now compiles and is much less toxic. It still is not a proper MLD implementation: (1) It is basically a port of IGMP, tweaked to work with IPv6 and ICMPv6 MLD messages, (2) it needs a proper analysis and comparison with RFC 3810, and (3) it is completely untested. For this reason, it will remain EXPERIMENTAL for some time.
