This might even have prevented the compiler from some optimizations,
since both signed and unsigned types are used for the dezigzag tables/
table pointers, and if a branches uses both the compiler needs to
create more complex code.

lf_delta.ref[i] and lf_delta.mode[i] were incorrectly reset to 0 if
specific delta value was not updated. Fixed to keep the previous value
if flag indicates that element in question is not updated.

Correct handling of errors to prevent hags or crashes is very complex
otherwise.
The frame initializing is also moved from decode_slice() to
decode_frame() for clarity.
