Mainly adding missing headers, removing redundant headers that induce undefined symbols or rearranging existing headers according to dependencies betheen them. Also add missing include paths to makefiles and make configs. Note: direct inclusion of pthread.h in disk.h is caused by the latter being used almost everywhere, including third_party libraries. Putting pthread.h there releases us from affecting more code. Basically fixes build for anything that is not default HiSi configuration.
