Revamp build process

* Build using CMake (http://www.cmake.org)
* Link with tcmalloc instead of dlopen
* Build on Windows by using MSVC
* Platform library hiding threads and mutexes
* Dropped support for UDP
* Ensure that the test applications run on windows!
* Rename binary to mcd (due to cmake name conflict with libmemcached)
