- glue and pylal both all export the .end property so this
  modification creates compatibility with both
- I hope to update the lal swig bindings soon as well
- refs #2288

- ligolw_thinca on master no longer makes use of this method
- refs #2287

- this argument does not convey e_thinca_parameter, it conveys delta_t

- precompute log(0.99) and log(0.01)

- refs #2229

- port code to functions in lalsimuation.  also change the padding formula
  from 1.1 * tchirp + 1 to 1.1 * tchirp + 3/flow.
- even with the original padding formula the results are slightly
  different.  e.g., with the ER7 "em bright" bank and an f low of 10 Hz,
  the old implementation determined the padding to be 175.7 s with a padded
  f flow of 9.647 Hz, while the same formula implemented with the
  lalsimulation functions determines the padding to be 179.8 s with a
  padded f low of 9.583 Hz.
- this also adds some input checking to avoid getting weird error messages
  from this code
- refs #2179

Change in functionality of gstlal_compute_strain as a full or partial calibrator.  Remove support for whitening functionality.
