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

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.

When sending a file descriptor via SCM_RIGHTS we also need to acquire an
open reference to it. Otherwise the descriptor could be closed while
being on the way. This fixes the ssh login problem with non-root users.

Added support for SO_PEERCRED for Unix sockets.

* Support the new {send,read}_data_no_buffer() protocol hooks to avoid
unnecessary data copies and waste of memory.
* Changed the storage backend to ring_buffer.

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 a bit more debug output in UnixFifo, but disabled debug output in
all files by default.

* Added support for SCM_RIGHTS (sending file descriptors).
* Fixed shutdown(). It was computing the wrong fifo flags and set the
wrong ones from the wrong variable on the peer fifo.
* Generally made the Unix sockets behave more like they should. E.g.
after closing one end, it must still be possible to read from the
other (as long as there are buffered data). Also fine-tuned when to
return what errors from recv()/send().

Protocol module for Unix domain stream type sockets. The implementation
is almost complete, but still quite buggy (receiving data has a good
chance to drop into KDL).
