Randall Stewart fc14de76f4 1) Adds the rest of the VIMAGE change macros
2) Adds some __UserSpace__ on some of the common defines that
   the user space code needs
3) Fixes a bug when we send up data to a user that failed. We
   need to a) trim off the data chunk headers, if present, and
   b) make sure the frag bit is communicated properly for the
   msgs coming off the stream queues... i.e. we see if some
   of the msg has been taken.

Obtained from:	jeli contributed the VIMAGE changes on this pass Thanks Julain!
