CVS patch #477161: New "access" keyword for mmap, from Jay T Miller.

This gives mmap() on Windows the ability to create read-only, write-
through and copy-on-write mmaps.  A new keyword argument is introduced
because the mmap() signatures diverged between Windows and Unix, so
while they (now) both support this functionality, there wasn't a way to
spell it in a common way without introducing a new spelling gimmick.
The old spellings are still accepted, so there isn't a backward-
compatibility issue here.

+- mmap has a new keyword argument, "access", allowing a uniform way for
+  both Windows and Unix users to create read-only, write-through and
+  copy-on-write memory mappings.  This was previously possible only on
+  Unix.  A new keyword argument was required to support this in a
+  uniform way because the mmap() signuatures had diverged across
+  platforms.  Thanks to Jay T Miller for repairing this!
