Code review request for 4206909 : adding Z_SYNC_FLUSH support to deflaters

[Xueming Shen]

Martin, Alan.

Finally got the CCC approval. Here is the final webrev
http://cr.openjdk.java.net/~sherman/4206909/webrev

The only difference compared to the  webrev you guys reviewed last time at
http://cr.openjdk.java.net/~sherman/zipflush/webrev is to use the Google 
copyright
in test case InflateIn_DeflateOut.java

Thanks,
Sherman
