Since the headers for cpu, memory and load functions are virtually the same for all platforms, I've decided to move them into common/ dir and do some refacotring: * removed per-platform header files * implemented get_cpu_count() function across all platforms. We are using it cpu on every platform, yet not on every one this was implemented as a separate function. * removed platform detection through preprocessor from main: we don't need this there anymore, since the headers are common for all platforms. CMake will handle setting of correct source files for us now. * Unified used defines for CPU states across all platforms and made linux use them. Added some platform detection to cpu.h in order to set them correctly across the platforms. * moved getsysctl.h to common/ dir, since it's used on Net and Free BSD, and thus become a common include.
