Resolve the conflict in binary_reader.hpp: develop dropped the document_size < 0 check in check_bson_document_size(), because sizes below 5 are rejected before they are stored. Here such a size is only stored after it was repaired, and the !size_repaired guard skips the check, so the check is dropped here as well. Regenerate the single headers.
