webrevs.2 for macosx changes to jdk7u-osx

[Michael McMahon]

Artem,

Thanks for looking at this!

Actually I just realised that your comments were on the changes relative 
to macosx-port.
I only included that webrev for reference, in order to identify if there 
were mac related
changes that I might have missed. So, that is why there are a number of 
files with no changes.

In any case, many of your comments are still useful. I have removed the 
extraneous definitions
from the makefiles. I also made the change to UIManager and java_props_md.c

The change from "malloc.h" to stdlib.h is a simplification because 
stdlib is actually the correct
include for malloc(), so it works the same on all platforms.

awt_LoadLibrary.c is a complicated change, and I'd certainly appreciate 
your view on the webrev
(relative to jdk7-osx) and indeed the other changes relative to jdk7-osx 
as well.

Thanks
Michael.
