For Windows, we are simply using calloc, which has two annoyances:
the memory has more permissions than needed by default, and it comes
from the process heap, which looks like a memory leak since this memory
is rightfully never freed.
This switches _rs_alloc on Windows to use VirtualAlloc, which restricts the
memory to READ|WRITE and keeps the memory out of the process heap.

other systems to fit into the same mold, so add copyright

Move <sys/mman.h> and raise(SIGKILL) calls to OS-specific headers.
On OpenBSD, move thread_private.h as well to arc4random.h.
On Windows, use TerminateProcess on getentropy failure.

It may make sense to later replace this with a Critical Section later.

into one if a system has an awesome getentropy().  In that case it
is valid to totally throw away the rsx state in the child.  If the
getentropy() is not very good and has a lazy reseed operation, this
combining is a bad idea, and the reseed should probably continue to
use the "something old, something new" mix.  _rs_allocate() can
accomodate either method, but not on the fly.

Most of these files just have their RCS/SCCS tags standardized.
Note that mpool.3 has not been updated to reflect the new mpool interface.

of include files now.  Added openBSD tags.
