Parser: remove global state

Browse source 
The parser had global state in the form of a linear regression
and the "plot_depth" variable. Collect that in the deco_state struct and
pass it down the call-chain. Move out the code to update the
regression data to not bother other callers of tissue_tolerance_calc().
