The CBOR, MessagePack, UBJSON, BJData, and BSON writers silently skipped the payload of a value_t::discarded value nested in an array or object, while still writing its slot in the element/member count (and, for BSON, its entry header), producing a binary document whose declared size does not match what was actually written. Throw type_error.321 instead, for a discarded value anywhere in the tree, including at the top level. Rewritten from the original PR against the current (non-recursive option aside) binary_writer.hpp, which has changed substantially since this was first proposed; the out_of_range.412 MessagePack size check and unrelated test reformatting from that PR are dropped as out of scope here.
