gstlal-calibration:  Added debugging element splitcounter for printing buffer timestamps and offsets to screen and file.

gstlal-calibration:  Example in tests/check_calibration/Makefile for using transfer function plotting script.

gstlal-calibration:  New plotting script in tests/check_calibration/plot_transfer_function.py to plot transfer functions.

lal_transferfunction:  added event() function back in to get best possible transfer functions at EOS.

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.
