out of the os-specific widget code and into the more generic command line code
in the toolkit.
This bug implements the corresponding changes for the QNX Neutrino Mozilla
based browser:
1) The xremote related code is removed from widget/src/photon/.
2) The nsPhMozRemoteHelper.* source files removed in step 1 are renamed to
nsPhRemoteService.* and modified to work under toolkit/components/remote/.
3) Finally the photon specific code in widget/src/xremoteclient is modified so
that the mozilla-xremote-client utility works as it did before.
These changes are all Neutrino-only and should not affect any other platform,
and in theory cannot bust any Tinderbox builds.
