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

gstlal_etg + multichannel_datasource.py: fixed issues reading in channel INI files, added option --channel-include to specify specific channels to read in from INI files

idq_multirate_datasource.py: commented out initial low-pass filter since it is not clear that we get the intended behavior for output triggers

gstlal_inspiral_injection_snr: made number of parallel processes a command line argument. Default = 1

gstlal_inspiral_pipe now uses reference_psd.cache for gstlal_median_of_psds

split up for computing injection snrs, then merged back together before
being merged with the associated injection LLOID files

committed with permission)

gstlal_inspiral_pipe: Remove FIXME that was addressed by commit 416627b7

- in the FIR-whitener code path

- only add a pre-whitener reblock element in the non-FIR whitener code path

- check that psd_fft_length is an integer
