The extra semicolons were introduced in 48b50cef together with the
defintion of the ZMQ_USE_SELECT macros.

The decision about the poller mechanism to use (select, poll, ...)
was done twice: once by the build system and once by the code in
poller.hpp. As the build-system can actually detect the mechanisms
available, prefer that result to the hard coded defaults in
poller.hpp.

At the same time, remove the duplicate detection of select() vs.
poll()-variant from proxy.cpp, signaler.cpp and zmq.cpp.

This patch has not been tested on many build platforms: especially
the cmake build needs testing / patching. For the other builds,
hard code the result as these these are all Windows platforms.

This reverts commit 0b92831b.

Added some missing (but existing in branch) files to libzmq11 project needed
to compile as static library by VS2012 (at least), and fixed some warnings.
One warning remains in raw_decoder.cpp, which I'm leaving for now because I'm
not sure how project owners would like to fix it.

Add platform.hpp as project dependency to vc100 and vc110 projects for local & remote throughput tests.

Use Multithreaded DLL Runtime, Debug/Release accordingly - need consistency for the czmq configurations

+ 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.

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

- tested for Windows CE 5.0 under Visual Studio 2008 Pro
- tested for Windows XP under Visual Studio 2008 Pro

- when compiling for Windows CE, a C++ project must define the preprocessor definitions: UNDER_CE=$(CEVersion),_WIN32_WCE=$(CEVersion)
- choosing the "_WIN32_CE" form for uniformization with "_WIN32" and "_WIN32_WINNT" already used in libzmq (boost is using both forms)
- see http://msdn.microsoft.com/en-us/library/ee479161(v=winembedded.60).aspx

- raw_encoder.cpp and raw_decoder.cpp in missing in MSVC project

MSVC build fails with linking errors for unresolved symbols SetSecurityDescriptorDacl and InitializeSecurityDescriptor in signaler.obj
Adding the relevant link library (Advapi32.lib) to VCLinkerTool fixes this (tested MSVC2010 on XP and Win7)

Without the LinkDLL statement, command-line compile using vcbuild attempts to compile EXE and complains about entrypoint
The LinkDLL statement forces the linker to produce desired output
