* Added two new files: errno.hpp and errno.cpp. They are required to use errno functionality on WM.
* zmq.cpp, msg.h: removed inclusion of errno.h because it is included in zmq.h that is also included by .cpp.
* windows.hpp: process.h is included only for desktop builds.
* thread.cpp: on CE CreateThread is used instead of __beginthreadex
* socket_base.cpp, clock.cpp: on CE include cmnintrin.h instead on intrin.h
* signaler.cpp: on Windows should use special macro around event name (for unicode builds)
* err.hpp: make it include errno.hpp (my file) instead on errno.h when building for CE
* err.cpp: use FormatMessage when building for CE (because CE does not have ANSI API functions)
* zmq.h: do not include errno.h whe building for CE
* libzmq.vcproj: add tro new files

pthread_* functions return the error number rather than
setting errno. This was not accounter for till now.

So far these were declared as C++ static functions which
was incorrect and caused warnings with SunStudio.

Sockets may now be migrated between OS threads; sockets may not be used by
more than one thread at any time. To migrate a socket to another thread the
caller must ensure that a full memory barrier is called before using the
socket from the target thread.

The new zmq_close() semantics implement the behaviour discussed at:

http://lists.zeromq.org/pipermail/zeromq-dev/2010-July/004244.html

Specifically, zmq_close() is now deterministic and while it still returns
immediately, it does not discard any data that may still be queued for
sending. Further, zmq_term() will now block until all outstanding data has
been sent.

TODO: Many bugs have been introduced, needs testing. Further, SO_LINGER or
an equivalent mechanism (possibly a configurable timeout to zmq_term())
needs to be implemented.
