Bulk request to backport 21 fixes to 11-dev for 11.0.7

[Kevin Rushforth]

Hi Johan,

We request approval to backport the following 21 fixes, which Guru and I 
prepared. Two of the 21 fixes, the GStreamer and Glib upgrades, were 
done as a single commit, so there will be a single changeset pushed for 
those two. By coincidence, that commit is the only one that didn't apply 
cleanly due to a minor merge conflict in one file as a result of an 
earlier fix (I had earlier fixed this same conflict in mainline). I 
uploaded the changeset patch with the conflict fixed here if you want to 
take a look:

http://cr.openjdk.java.net/~kcr/8230610/8230610.patch.zip

All other patches apply cleanly, ignoring the copyright year in one file 
for one of the patches.

Here is the list of bugs
