In the redaction list traversal code, there is a bug in the binary search logic when looking for the resume point. Maxbufid can be decremented to -1, causing us to read the last possible block of the object instead of the one we wanted. This can cause incorrect resume behavior, or possibly even a hang in some cases. In addition, when examining non-last blocks, we can treat the block as being the same size as the last block, causing us to miss entries in the redaction list when determining where to resume. Finally, we were ignoring the case where the resume point was found in the buffer being searched, and resuming from minbufid. All these issues have been corrected, and the code has been significantly simplified to make future issues less likely.
