Changed the shapes of MASS and TMass members of the All_variables struct as part of caps_per_proc removal
Changed the shape of VI and EVI members of All_variables as part of
caps_per_proc removal. Corrected the signatures of get_system_viscosity,
visc_from_nodes_to_gint, visc_from_ele_to_gint, visc_from_gint_to_nodes,
visc_from_gint_to_ele, apply_low_visc_wedge_channel, visc_from_P,
visc_from_T, visc_from_S, visc_from_C, visc_from_mat
Changed the shape of PN and slice members of All_variables as part of caps_per_proc removal. Corrected the signatures
of compute_nodal_stress, free_STD_mem, allocate_STD_mem, get_STD_topo,
get_STD_freesurf, get_CBF_topo, full_exchange_snode_f,
regional_exchange_snode_f, sphere_expansion, p_to_nodes
