Memdown Sync

[ccorcos]

Making levelup work synchronously is going to involve a ton of work.

Level/leveldown#372

Instead, I've simply patched over a few files and compiled it all into a single file using ncc and it works!

I'm very much opposed to this solution (monkeypatching, having compiled code, maintaining this when APIs change) which will cost us time in the long run, so I rather we do it properly from the start.

I totally agree. Just wanted to leave this here for anyone else looking for a solution. It was a fun challenge for me ;)

I would also mention that createReadStream doesn't work with this solution. Ideally the streaming api would just use an IterableIterator and AsyncIterableIterator instead of the stream.

Right now I'm just creating my own abstraction around memdown and that's a lot easier. I have to do the encodings myself though.
