Fixed wrong indent
Changed auto child advance back to backwards linear search for getting subset of coords and samplers array of a child
Used offset from parent instead of backwards linear search to find a child proc's coords and transforms in Auto...Advance
append mangleString to variable name in nameVariable()
BUILDS! Added AutoFragmentChildProcAdvance class; fixed a few errors from previous commits

Changed childProcessor(i) to return const referencd
Fixed rootProc/parentProc offset issues; renamed a few things.
added nonempty check to gatherTransforms to avoid segfault
removed recursive append_gr_coord_transforms() from GrGLProgramBuilder
BUILDS! Changed num*includeProc() calls to num() calls
added gatherCoordTransforms(). added coordTransforms() for root proc only
Modified GrFragmentProcessor to append child proc transforms and textures to root proc's arrays.

Since only XP's can read dst now, there is no reason to have this query on GrFP.
This also triggered a chain reaction of cleaning up/removing unnecessary code
elsewhere.
