Backport of 8231991 & 8234107 to 13u, 11u and 8u

[Mario Torre]

Hi all,

I would like to backport 8231991 and 8234107 all the way down to 8u.

The backport is identical for all versions (except the paths in 8u
obviously), but is slightly different than the patch for 14dev, first
of all because the two changes have been merged into one, but most
importantly because I decided against introducing the two new constants
in sun/awt/X11/XConstants.java and instead went to have those values
directly copied in the code where they are used.

Cheers,
Mario
