Mark Mentovai	b666bcbe98	win: Use signed int as the integer representation of HANDLEs ... HandleToInt() and IntToHandle() use int, a signed type, for the 32-bit integer representation of HANDLE values. For opaque values, an unsigned type would normally be used, but in this case, signed was chosen for sign extension to work correctly. INVALID_HANDLE_VALUE is defined as ((HANDLE)(LONG_PTR)-1), and this needs to round-trip through the chosen integer representation back to the same HANDLE value. Sign extension is also recommended by https://msdn.microsoft.com/en-us/library/windows/desktop/aa384203.

Mark Mentovai	2eeaa3ac54	win: Add HandleToInt() and IntToHandle() ... This consolidates all of the twisted casts and comments that discuss how HANDLEs are really only 32 bits wide even in 64-bit processes on 64-bit operating systems into a single location.
