- use stream_thinca's discard_boundary and a bisection search to clip the ratebinlist objects to the range of segments we actually care about

- fails with AttributeError if invoked before any triggers have been processed.
- this patch fixes by setting a default value for .coincideice_backoff of .max_dt

lal_transferfunction:  if transfer function of fir filter generation fails for any reason, immediately try again.

- precompute list of times when two or more instruments were on to reduce operation count in loop over triggers for inclusion in denominator

gstlal_etg_template_overlap: stripped out waveform functions copied over in gstlal_etg in favor of refactored waveform class in idq_utils.py

renamed idq_aggregator.py -> idq_utils.py, refactored gstlal_etg waveform functions into idq_utils.py, cleaned up gstlal_etg code for readability

gstlal_etg_whitener_check: fixed issue causing whitened timeseries to not be produced, added progress reports if verbose, removed unnecessary fluff

gstlal_etg: added missing kwarg in finding template durations which may cause incorrect length of templates

gstlal_etg: added missing kwarg in template lookup table causing wrong frequency, Q to be stored to disk

gstlal_etg: removed unused option latency to print latency information to disk (stored in logs now) throughout

- add tail optimization to .add_ratebin() to try to improve trigger generator performance especially with large numbers of disjoint trigger segments.
- NOTE:  the correct fix is for injection jobs to not record any trigger statistics at all, but that would be t0o invasive a change at this late date.  something for O3

- the newly resurrected stock python plugin loader induces segfaults in gstlal if the two are installed together, and there is no work-around.  we will be transitioning to the stock loader for O3 but for the time-being we need to add the conflict to the package data to prevent breakage.

gstlal_compute_strain:  added option to remove DC component from residual and control channels before filtering.

the user to specify columns will will be used for gps times (and thus should
have no commas) and columns will should be displayed in scientific notation
(currently, that is only the FAR and FAP columns in the candidate table).
Modified gstlal_inspiral_summary_page to take advantage of these new kwargs

lal_resample:  found downsampling bug that counts samples incorrectly when the first timestanp is not a multiple of the longer sampling period

datasource.py: Added rate kwarg to mksegmentsrcgate
multirate_datasource.py: Pass max rate to mksegmentsrcgate

added gstlal_etg_whitener_check exec to check output from whitener, changed Makefile.am to reflect this

- expand tests of trigger_rate module to cover .coalesce() method
