HierarchSearchGCT: properly initialize usefulParams

 -specifically, this sets BSGLsetup=NULL
  which fixes a segfault in XLALComputeExtraStatsSemiCoherent()
  for --computeBSGL=0

Restore correct distance units after BAYESTAR MCMC

I scaled all of the distances in the problem to the maximum SNR=1
horizon distance amongst all of the detectors. This was harmless for the
Gaussian quadratures version of BAYESTAR because the distance was a
marginal parameter. However, the MCMC version has an option to save the
sample chains, so it is useful to save the output in Mpc.
LineRobustStatsTest: numerics and convention fixes

 -change internal variables from REAL4 to REAL8 to avoid overflows
 -consistently use log10BSGL, i.e. for test output
  convert from old to new instead of new to old
