Revert "makefile changes for gcm javadocs"

We don't build it, nor do we have these sources.

This reverts commit 5f9922d7c3bce158e4c7a58929d4075e7c91e32e.

services: don't clear wallpaper when SystemUI
disconnects.

When we restart SystemUI (or the user), sometimes
the wallpaper would get cleared. This patch just
captures its originating component and
if that is our SystemUI component, ignore the event.
