9ade5b804e lzo: fix overflow checking in copy_backptr()
The check `src > dst' in the form `&c->out[-back] > c->out' invokes
pointer overflow, which is undefined behavior in C.

Remove the check.  Also replace `&c->out[-back] < c->out_start' with
a safe form `c->out - c->out_start < back' to avoid overflow.

printing as well.

This is based on the ffescape tool code, with a few extensions and fixes.
