Although our compile-time environment is set up so that we always support long files with 64-bit off_t, we have no guarantee whether off_t is the same type as int64_t. This requires casts when printing values, and prevents us from directly using qemu_strtoi64() (which will be done in the next patch). Let's just flip to uint64_t where possible, and stick to int64_t for detecting failure of blk_getlength(); we also keep the assertions added in the previous patch that the resulting values fit in 63 bits. The overflow check in nbd_co_receive_request() was already sane (request->from is validated to fit in 63 bits, and request->len is 32 bits, so the addition can't overflow 64 bits), but rewrite it in a form easier to recognize as a typical overflow check. Rename the variable 'description' to keep line lengths reasonable.
