Unblock server on multiple HTTP requests

[kevinkassimo]

Closes #1 .
Resolve the immediate cause for blocking, by making new conn accept and readRequest of same level and async, with Promise.race. Now http_test.ts should work properly.

(Currently there will be warnings of Promise resolved after resolved. The warning would go away after denoland/deno#1273)

Socket is closed for now once responding. Will need to change this behavior later. Sockets are left open now until EOF.

I'm not quite sure if this fix is proper, and whether I should keep serveConn (since it is exported)
I will work more on http based on feedback for this change.

@zhmushan It’s a deno issue, see denoland/deno#1273

Sorry, I just saw this issue.😭

Nice work - I'm glad you got it working :)
It's unfortunate that this logic is so complex now.. Isn't there some simpler way this can be done? Ideally without using Promise.race ?

[kevinkassimo]

Kinda bit stuck with implementing a simpler logic. (After getting rid of Promise.race I would really hope that the deferred and new array each time could also go away...)
