[et-mgmt-tools] [PATCH 5/5] "Launch virt-viewer" (new) browser plugin.

"Launch virt-viewer" (new) browser plugin.
- Based on npshell from xulrunner 1.9.0.
- Includes test page.
The file 'npunix.c' is pretty much identical to what is in xulrunner
1.9.0, except that I made a few const-correctness fixes.
The file 'npshell.c' is only minimally modified from what is in
xulrunner, just changed so that it calls the new plugin entry points.
The interesting stuff happens in 'launcher_plugin.c' and 'test.html'.
The easiest way to test this is:
./autogen.sh --enable-plugin
make
cp plugin/virt-viewer-plugin.so ~/.mozilla/plugins/
firefox `pwd`/plugin/test.html
