RFR : 8044725 :Bug in zlib 1.2.5 prevents inflation of some gzipped files (zlib 1.2.8 port)

[Seán Coffey]

I'd like to port the zlib v1.2.8 libraries to JDK 7u. Currently, 7u uses 
zlib v1.2.3 libraries. 8u20 was recently upgraded to 1.2.8. zlib fixes 
since 1.2.3 can be found at 
http://cr.openjdk.java.net/~coffeys/webrev.8044725.7u/webrev/raw_files/new/src/share/native/java/util/zip/zlib-1.2.8/ChangeLog

While porting, I noticed that the Program.gmk had a bad reference in it 
to zlib 1.1.3 (JDK6  version) - I've corrected that to 1.2.8 for now but 
question if the extra INCLUDE directive is even needed.
