doc: document MSG_ZEROCOPY
Documentation for this feature was missing from the patchset.
Copied a lot from the netdev 2.1 paper, addressing some small
interface changes since then.
Changes
v1 -> v2
- change email discussion URL format
- clarify that u32 counter is per-syscall, unsigned and
wraps after UINT_MAX calls
- describe errno on send failure specific to MSG_ZEROCOPY
- a few very minor rewordings
