Subject: [PATCH] WINCHAIN - a framework allowing multiple processors between
 core and winport This is the code I built trying to figure out the large
 window size issue. It completely compiles out if not needed (see -DWINCHAIN
 in hints/macos10.7) and except for one call during setup has zero overhead if
 compiled in and not used.  See window.doc for more info.

Defs for UNUSED parms.  I know this has been controversial, so use is isolated
to the chain code and windows.c (where it shouldn't be intrusive and saves about
50 warnings).

Hints file for 10.7, but the build process still needs to be migrated from
the branch.

Backporting notes:
- Only take UNUSED from upstream
