* Finished groundwork on ICMP by introducing a completely protocol agnostic
error mechanism.

* First part of ICMP support: this is based on the work by Ivo Vachkov (GSoC
2007), and Yin Qiu (GSoC 2008). And even though I needed to rewrite pretty
much all of it because of the countless bugs and problems it had, it still
shares the same architectural problems of introducing a domain dependent
error mechanism to the upper layers, and needing the
net_buffer::network_header hack. This I will rework later.
* net_buffer's append_size(), and prepend_size() will now gracefully handle
buffers without a data node.

Applied patch by Ma Jie adding functionality needed by mDNSResponder:
* added new protocol method process_ancillary_data_no_container() that does not
need a container to fill the cmsghdr data.
* Added support for the IP_RECVDSTADDR option using this call.
* Implemented support for IP_MULTICAST_IF.

* Added optional {send,read}_data_no_buffer() hooks to the protocol
module interface. They directly operate on iovecs and thus allow
protocols that don't need it to avoid the creation of a net_buffer.
* Adjusted the socket module to support the new hooks. If they are
present, they will be chosen over the old hooks.

Moved the container management for ancillary data from the net_buffer
module to the stack module. There's a dedicated struct
ancillary_data_container, now. One can just set the container on a
net_buffer.

Added support for sending/receiving ancillary data. The protocol modules
have two more optional hooks for attaching supplied ancillary data to a
net_buffer and for processing received ancillary data. Not sure, if that
is flexible enough for all kinds of ancillary data, but it is for
SCM_RIGHTS and also should for SCM_CRED[ENTIAL]S (if we ever decide to
implement one of those) -- don't know any other types on other protocol
levels.

* Added flags field in net_protocol_module_info; there is currently a single
defined flag: NET_PROTOCOL_ATOMIC_MESSAGES.
* socket_send() now honours NET_PROTOCOL_ATOMIC_MESSAGES and returns either
EMSGSIZE if the data to be send is larger than net_socket::send::buffer_size,
or divides the data in appropriately sized chunks.
* This fixes sending >=64K over a TCP socket at once (TCP would just have
returned an error in that case).
* TCP now overrides the default send buffer size (to 32768 for now).
