Change RAND_poll for Unix to try a number of devices and only read

them for a short period of time (actually, poll them with select(),
then read() whatever is there), which is about 10ms (hard-coded value)
each.

Separate Windows and Unixly code, and start on a VMS variant that
currently just returns 0.
