- in PyArg_ParseTuple()

- the timestamps are a mix of nanoseconds and LIGOTimeGPS objects, this
  patch cleans up where the conversions occur.  motivated by a screw up
  related to this

- to enable triggers to carry SNR snippets with them.

- expose --min-instruments command line options on gstlal_inspiral, gstlal_inspiral_create_prior_diststats and gstlal_ll_inspiral_create_prior_diststats

- helps prevent signals from contaminating noise models.
- relies on the previous change to lloidparts that records active segments
  with semi-closed segments extending to +inf

- .current_segment_start is removed, instead semi-closed segments are stuck onto the end of each segment list when an "on" transition occurs, and they are clipped when an "off" transition occurs
- this makes it much easier to determine which instruments are beleived to be on at a given time
- it makes the task of check-pointing more straight forward as the segments can be just written to disk as-is
- the "cumulative segments" are renamed to "recent segment history" because they are not cumulative, they are only a look-back into the recent past
- but the bottle route is left unchanged for compatibility with external tools

- GstMessage objects carry a timestamp field themselves, just use that

For years he's refused to silence the uninitialized data warning, saying
"its fine!" so I'll do it my own self

sheesh.

- retrieve threshold from process_params table

New element lal_insertgap can be used to gap or replace undesired values in a data stream.

- this has been removed from the ligolw_thinca library code so we need to do it ourselves if we want to.

- to bank_filename of gstlal_snglinspiral_array_from_file()

- free() --> LALFree()

- .last_coincs object now provides frozenset of zero-lag time slide IDs which allows for faster identification of zero-lag coincs

- need to explicitly exclude self or things get weird

- related to ranking statistic rework

- fix a bug in a delta_t check
- add some more compatibility checks of CoincParams objects

- get this information from the coinc_params_distributions object instead
