suzerain: #3021 rework deltaH -> deltah

I mistakenly had used total enthalpy instead of internal enthalpy.
Using the latter introduces lots of API changes into the BL routines.
Took this as a chance to clean up some other API-related nits.

bl.h/bl.c:
  * Avoid passing a gsl_matrix scratch buffer when vector will do
  * Avoid repeatedly allocating gsl_integration_glfixed workspaces
  * Pass code_Ma and kinetic energy around so that h can be
    computed from H0, ke, and code_Ma.
  * Rename "deltaH" to "deltah"

test_bl.hpp:
  * Calling conventions to match bl.h
  * Updated tests for change in delta3 definition

driver_base.cpp:
  * Output "deltah" instead of "deltaH"

profile.hpp/.cpp:
quantities.hpp/quantities.cpp:
  * Now gather kinetic energy (ke)
  * Calling conventions to match bl.h
