Replace uses of obsolescent BReference[able] API.

headers/private/kernel/util/OpenHashTable.h, Hugo's version, is a bit nicer than
Tracker's OpenHashTable.h which it should eventually replace. We've renamed the
class to BOpenHashTable and changed the interface slightly so that HashTableLink
became superfluous.
Adapted all the code that used it. Since the OpenHashTables no longer clash,
this should fix the GCC4 build.

Fixing all headers/namespaces/name lookup problems that hinder a GCC 4.3.2
build. I sure hope that this doesn't break the build for anyone else.

* Replaced all instances of benaphores in the kernel code by mutexes.
* Removed kernel benaphores.

* 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.

* 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).
