Dean Troyer e3a9160c0d Fix Neutron plugin XTRACE handling
The various Neutron plugin files need to have unique variables for the
xtrace state as they are sometimes nested more than two levels deep
and MY_XTRACE is getting stomped.  This gives each of the neutron_plugin
and neutron_thirdparty include files a unique XTRACE state variable.

I don't think this is a problem with any of the other plugin include
files (yet) so this just handles Neutron for now.
