This adds generic APIs to libqb for handling thread's, mutex's, and condition variables. On Linux and OSX these are implemented via the ones provided by pthreads. On Windows they're implemented via the ones provided by the Win32 API. For compiling, the code itself is not conditional, but the Makefile includes logic to decide which implementation to pick. Note that it would have been nice to simply use std::thread and friends from C++11, however using them on MinGW appears to be a bit messy. Since using the Windows ones directly isn't that hard this was an easy compromise.
