* Starting draft ZMTP/2.1 protocol (revision 2)

* Maintains backward compatibility

Copyrights had become ads for Sustrik's corporate sponsors, going against the original
agreement to share copyrights with the community (that agreement was: one line stating
iMatix copyright + one reference to AUTHORS file). The proliferation of corporate ads
is also unfair to the many individual authors. I've removed ALL corporate title from
the source files so the copyright statements can now be centralized in AUTHORS and
source files can be properly updated on an annual basis.

Adapted zmq_socket_monitor man page to new API.

Changed message structure for event notifications

Simplified zmq_event_t structure.

Simplified the zmq_event_t structure for easier access and better usability towards language bindings.

Fixed Linux compilation problem

remote_thr.cpp: port pthreads usage to win32 api

this follows what {local,remote}_lat.cpp and inproc_{thr,lat}.cpp do.

Windows: Fix rounding error in now_us. [Jira LIBZMQ-514]

Improve accuracy of time calculations and avoid division by zero when
ticksPerSecond.QuadPart < 1000000.

Improvements and fixes for performance of PUSH/PULL in local_thr and rem...

- option to set number of zmq threads on the command line for local_thr
- option to set number of zmq_threads and workers in remote_thr
- option to set SND/RCV buffer sizes on command line
- option to set whether to PUSH/PULL on command line
- option to set to use zmq_recv or zmq_msg for transfer on command line
- better timing function
- corrected and improved throughput reporting
- HWM and DELAY socket options

Fixed overflow in results calculation

Static Library Linking for Windows

+ ignore StaticRelease & StaticDebug intermediate files

- New ZMQ_STATIC flag to enable "libzmq.lib" Windows static library (or "libzmq_d.lib" in Debug mode).
- ZMQ_STATIC needs also to be defined by projects using static linking against "libzmq.lib"
- New StaticDebug & StaticRelease configurations for libzmq Win32 projects under MSVC 2008 & 2010
- Tested with Visual Studio 2008 Express under Windows 7, and Visual Studio 2010 Express under Windows 8.

Fixed module path with cmake < 2.8.3

Corrected linking error in MSVC 2010 build + perf/projects compilation

Fixed MAXMSGSIZE setsockopt, which I'd broken

VS2008 & VS2010: adding the pre-build command to copy platform.hpp in perf/ directory to the two appropriate projects, for each MSVC version

- raw_encoder.cpp and raw_decoder.cpp where missing in Visual Studio 2010 project

Windows CE support : using standard _WIN32_WCE flag instead of WINCE

- Windows CE does not manage security attributes (no SetSecurityDescriptorDacl(), SetEvent (NULL, xxx) ...)
- Windows CE does not inheritance of sockets for child process (SetHandleInformation ((HANDLE) *w_, HANDLE_FLAG_INHERIT...)
