win32: use 64-bit time on 32-bit platforms

To avoid problems with dates in 2038 and beyond use 64-bit time
values on 32-bit platforms.

- Mostly this just requires a few preprocessor macros to choose
  the appropriate functions, structs and typedefs.

- We have our own implementations of nanosleep(), clock_gettime()
  and clock_settime().  Omit the Windows include file that declares
  them.

- Apply the hack for struct timeval in the 'ts' applet on 32-bit.

Adds 1624 bytes on 32-bit, none on 64-bit.
