inspiral_pipe: convert infinities to something that follows the T050017 spec... FIXME this is not ideal...

gstlal_ll_inspiral_daily_page: switch to offline style clustering, fix issue with plot directory and use the new gstlal_inspiral_summary_page_lite

gstlal-calibration:  Improved methods for doing noise subtraction multiple times using different witnesses in series.

fxtools/multichannel_datasource.py: fix issue with individual channels requested from INI files not being added. feature_synchronizer: fix issue where pipeline was crashing after some time due to not flushing messages from queue

datasource.py: add options in lvshm live source to set the assumed duration and block size of the shared memory partition

Makefiles are not configured to build itacac, and it will not work
without a patch for gstlal_snglinspiral that will be pushed yet

- test_commpn.py:  Seeking pipeline seems to work now.
- pcal-to-darm plotting script:  now works in new setup.
- gstlal_compute_strain: removed stray dq_epics variables

feature_extraction: tidy up options, fix hdf5 sink issues with reading ini files, extra tweaks in dag generation/Makefiles for online

gstlal-calibration:  Using Makefile to generate directories with filters when needed, but these directories are in .gitignore, so they will not be part of the gstlal repo.

gstlal-calibration:  removed git submodules with git-svn directories, which did not work the way we had hoped.

gstlal_compute_strain:  Split the PUM and UIM stages of the actuation and calculate kappa_PUM and kappa_UIM separately and apply them.

- reflects as-built changes included in the 1.5.1 packages.

feature_extractor: update synchronizer/sink to deal with variable sample rates, update Makefiles to process channel INI files seamlessly

(fixes bug where uploads with files from coinc_extractor wouldn't show
sngl_inspiral contents on gracedb, at least as recent as Feb 2018)

gstlal-calibration:  Added git submodules with calibration filters from the calibration SVN. The submodules were made using git-svn.

- unmaintained on master, auto* scripts becoming increasingly verbose about problems in the build scripts in that directory
