Take no send larger than a receiver holds: 16 MiB, not 64
A sender took sends up to 64 MiB, but a receiver holds 16 MiB of a
stream not yet stored, so a send between the two went again forever.
The most a send may be is now PURE_LINK_RECORD_MOST, what a receiver
holds; test-link sends one that large whole and is refused one byte more.
