kernel & add-ons: Adjustments to use DoublyLinkedList::InsertBefore.

The Insert(before, element) function has been marked deprecated since
2010, but still had many usage and kept accumulating more. It's long
past time we got rid of all them and actually deprecated the function
itself.

Insert(before, element) just calls InsertBefore, so no functional change.

net_interface & datalink: Fix MTU handling.

The device is what actually controls the MTU, and it has its own
field for this, so having a second one just meant the MTU never
got updated after startup.

Remove the "mtu" field from the interface, use the "device->mtu" directly,
and then actually invoke device->module->set_mtu when updating.

ipv4 & ipv6: remove_trailer() uses a positive size as parameter

Fix some usages of BStackOrHeapArray.

Validates the buffer with IsValid() before actually using it. Thanks Rene!

ipv6: avoid unbounded stack usage in send_fragments().

ipv4/6: fixed crossing link fields from different hash tables.

ipv6: Fix tracing int sizes on non-32-bit systems

Remove useless includes of khash.h

* These files were already converted to BOpenHashTable.
* For #9552.

Fix out of bounds access.
key.first is a pointer, so we shouldn't use the & operator here.
CID 610870 and 610871.
Should also fix ticket #9184. At least I cannot reproduce it anymore.

ipv6: added missing put_interface() call.

* Thanks to Stefano for pointing this out!

The sFragmentLock was never being initialized.

* This fixes bug #8958.

Fix multicast double free issue in IPv4.

- IPv4 had the same problem as v6. Most likely this was an oversight
when converting from a C to a C++ module. Might help with #6736 and
#8894.

Fix ticket #8870.

- multicast_address was being freed twice in ipv6_uninit_protocol(),
causing a panic on exit in apps that made use of it.

ipv6: Fix ability to disable ipv6 tracing. Disable ipv6 tracing

ipv6: bit of style cleanup. No functional change

* Converted the hash used to the BOpenHashTable instead of khash - basically
just applied r38391 to the IPv6 code (no time to resolve the TODO, and put
that into a shared class).
* Fixed failure on init handling.
* Not tested, but should work at least better than before, as the hashtable has
never been initialized before...
* This closes bug #7795.

Patch by Atis Elsts from GSoC 2010 that was overlooked.
- Adds IPv6 fragmentation support and some partial work to enable configuration of IPv6 in net_server. Not currently in the build.

into a working state after the latest stack changes.

error mechanism.

Work in progress commit by Atis Elsts (I'm posting his ChangeLog comments
directly here), I made only a few style changes:
* introduced 'has_broadcast_address' field in
struct net_address_module_info
- REVIEW: the name, and the status of this field for UNIX and L2CAP
families
* ipv6 address family support
* ipv6 address printing
* ipv6 protocol support
* ipv6 multicast support
- TODO: add and remove multicast routes in a more proper way
- TODO: support MLD
* ipv6 datalink protocol support
* icmpv6 protocol support (EchoRequest and EchoResponse messages)
* ipv6 neigbor discovery protocol support
(Advertisement and Solicitation messages)
- TODO: only the very basic support is present,
the protocol state machine is by no means completed
- TODO: replying to Solicitation does not work too good ATM
(visible, when pinging Haiku from outside)
* added Jenkin's hash algorith
* minor changes in existing IPv4 code - cleanup function
ipv4_get_loopback_address(), written by myself
* add tests: raw, udp, tcp/udp, mullicast sender
* add 'hoplimit' field in struct net_buffer
- TODO: this is just a hack, more generic approach would be better.
* add 'receive_data' function pointer in
struct net_datalink_protocol_module_info
- TODO: this is also more like a hack, to support information
passing from ICMPv6 to IPv6_datagram level.
