This is a squash of several commits that introduces
a new struct of waveform flags into the LALSimulation
ChooseTD/FDWaveform functions. It also adds a number of
functions to manipulate the struct and changes all calls
to ChooseTD/FDWaveform.
The original commit messages are below
Added new LALSimInspiralWaveformFlags struct that will be passed to
ChooseWaveform functions and control special behavior of
some waveform routines in the LALSimulation package
NOTE: This commit does not swig wrap the new struct
Changed ChooseWaveform functions to use new WaveformFlags struct
Fixed Conflicts in:
	lalsimulation/src/LALSimInspiral.c
Changed functions which call ChooseWaveform to use the new WaveformFlags struct
Fixed Conflicts in:
	lalinspiral/src/LALInspiralWave.c
WaveformFlags IsDefault functions now return bool
Made WaveformFlags an obscure struct
Improved ABORT macros in LALSimInspiral
Fixed Conflicts in:
	lalsimulation/src/LALSimInspiral.c
