Add blogpost of Mio 0.7 alpha 1 announcement

[Thomasdezeeuw]

This announces Mio 0.7 alpha 1.

There are a number of TODOs left which I'll clean up during the course of the week, I just wanted some feedback. My personal writing style is a bit impersonal and we might want to change that.

/cc some major contributors to the release @carllerche, @PerfectLaugh, @kleimkuhler, @asomers, @FXTi.

P.S. English isn't my first language and I'm (very) dyslexic so there will be grammar/language mistakes :)

[Thomasdezeeuw]

@sfackler mentioned on chat that Linux < 4 is a little broad. I need to figure out what minimal Linux version we actually support.

Also see tokio-rs/mio#1072 and tokio-rs/mio#853.

[asomers]

Thanks for writing this blog post. It will be very helpful to mio's users. But there's one big question that it doesn't address. How can a mio 0.6-based crate that implements Evented move to mio 0.7? That's the situation that mio-aio is in.

Some spelling and grammar edits. I hope they're useful!

[Thomasdezeeuw]

Thnak you @asomers and @hawkw for the thorough review. I've fixes all problems you've indicated, please let me know if I missed any or if you found more.

[Thomasdezeeuw]

@asomers fixes the last two things.

This something that the blog post is indeed missing. For mio-aio I think you can register the fd directly using SourceFd.

Mostly typo comments

[Thomasdezeeuw]

Thanks @kleimkuhler I've fixed all bugs.

[Thomasdezeeuw]

I meant type-o's, it's getting late here.

[kleimkuhler]

Thanks!

[dtacalau]

Looks good!

@Thomasdezeeuw what about adding a blurb like this at the top:

We are excited to announce [Thomas de Zeeuw][Thomasdezeeuw] as
the new lead of Mio. Mio is the low level I/O portability abstraction that
backs Tokio and other Rust projects. Thomas has been behind most of
the Mio 0.7 effort and will be continuing to lead the crate to 1.0. He has
written the rest of the announcement.
