Reimplement JS's sqlite3_bind_text/blob() with hand-written bindings to permit more flexible inputs. Add automated JS-to-C function conversion to sqlite3_busy_handler(). sqlite3.wasm.xWrap()'s '*' argument conversion no longer treats JS strings as C-strings: those conversions require explicit opt-in via the 'string' converter (or equivalent).
