nanosleep patch 1

["Pierre A. Humblet" <pierre at phumblet dot no-ip dot org>]

This is part 1 of the patch I sent yesterday.
See previous mails for background  info.
Here are some more details:

hires_ms::minperiod    Make NO_COPY for per process initialization.
hires_ms::resolution   For use in sleep and alarm
hires_ms::dmsecs       Ditto
_DELAY_MAX             Ditto
hires_ms::~hires_ms    Delete, rely on Windows end of process cleanup.
                       Note that previous version could call timeEndPeriod
                       even when timeBeginPeriod had not been called.
