- no benefit from having these as constants, since any modern compiler
  will compute them at compile time
- not consistently used, some codes define their own constants, etc.
- not used in newer LALSimulation codes
- ninty4by3etc kept, but moved into source files where it is used
- LALINSPIRAL_PNTHETA and LALINRPIAL_PNLAMBDA removed, not used anywhere
- passes 'make check'
