Build: Add very limited experimental CMake support. This does *NOT* replace the Autotools-based build system in the foreseeable future. See the comment in the beginning of CMakeLists.txt. So far this has been tested only on GNU/Linux but I commit it anyway to make it easier for others to test. Since I haven't played much with CMake before, it's likely that there are things that have been done in a silly or wrong way and need to be fixed.

Build: Fix bugs in the CMake files. Seems that the phrase "add more quotes" from sh/bash scripting applies to CMake as well. E.g. passing an unquoted list ${FOO} to a function that expects one argument results in only the first element of the list being passed as an argument and the rest get ignored. Adding quotes helps ("${FOO}"). list(INSERT ...) is weird. Inserting an empty string to an empty variable results in empty list, but inserting it to a non-empty variable does insert an empty element to the list. Since INSERT requires at least one element, "${CMAKE_THREAD_LIBS_INIT}" needs to be quoted in CMakeLists.txt. It might result in an empty element in the list. It seems to not matter as empty elements consistently get ignored in that variable. In fact, calling cmake_check_push_state() and cmake_check_pop_state() will strip the empty elements from CMAKE_REQUIRED_LIBRARIES! In addition to quoting fixes, this fixes checks for the cache variables in tuklib_cpucores.cmake and tuklib_physmem.cmake. Thanks to Martin Matuška for testing and reporting the problems. These fixes aren't tested yet but hopefully they soon will be.
