Hash :ff2a134d Message :Fix getpid() usage on Windows
On Windows, getpid() is _getpid(), and requires that we first include
<process.h>. arc4random.c previously didn't know that.
Actually, I question whether arc4random needs to do its getpid() tricks
on Windows. They exist only so that we remember to re-seed the ARC4
cipher whenever we fork... but Windows has no fork(), so I think we're
in the clear.
