e14006d0de Modify the {quote: IdxDelete} opcode so that it takes an array of registers rather 
than a record formed using {quote: MakeRecord.}  This avoids a needless packing
and unpacking of the record to be deleted. (CVS 4916)

3088d59e06 Add a completely new testing system for the Bitvec object. The new 
testing system uses sqlite3_test_control() instead of unpublished
APIs.  Now provides 100% condition/decision coverage.  Obscure bugs
in Bitvec found and fixed as a result of the enhanced coverage. (CVS 4902)
