Refactoring cont.
Many changes in BSDX08. Extensive changes in BSDX31. Creation of BSDXAPI1 as continuation of BSDXAPI.
BSDXUT1 now has UTs for BSDX31. Transactions now gone from BSDX08 and BSDX31.
BSDX08 needs more tests at failure points. BSDX31 still needs analysis for transaction failure and
code for rollback points, plus tests for that.
