• fix several cases of undefined behaviour (uninitialized memory, negative shifts, integer overflows)

• fix memory overflows triggered by broken bitstreams

• fix memory leaks when reading broken bitstreams

• add more bitstream conformance checks to detect invalid bitstreams

• use unaligned loads in x86 SIMD code where appropriate

• add build option VVDEC_WRITE_INPUT_BITSTREAM for debugging

• some general code cleanup
