Flash HTTP server rewrite - umbrella issue

We are working on a rewrite of Flash server (Deno.serve() API) to make it single threaded and fix problems related to current implementation.

Following issues should be closed by the rewrite:

We changed implementation of "Deno.serve()" in 2846bbe and removed "flash" completely in 51d3fb7.

Remaining open issues were changed to reflect they are now considered with "Deno.serve()" API in general, but no longer with "flash" implementation.
