Better Cygwin support.

- configure.ac: Add -lpthread only if acx_pthread_ok is yes. In cygwin, we use Windows' thread so that we don't need -lpthread.
- base/mutex.h: Define NOMINMAX before we include windows.h.
- glog/*.h: Make sure that dllimport doesn't appear in cygwin. Note that windows.h may define _WIN32 macro.
- utilities.h: Define OS_CYGWIN.
