Merge #1292
1292: Support `TCP_MAXSEG` TCP Maximum Segment Size socket options r=asomers a=eaon
Found myself in a situation where I needed to advertise a specific MSS. Thought this crate is the appropriate place for this feature (especially since the `TCP_MAXSEG` const was exposed through it before), so here goes.
Actual change is of course tiny but it comes with a test. Happy to make changes, especially since I need to do more research on which platforms this works.
