Add cont, buf-conn, http2, pg, pg-types, racket-tcp, web-server-racket, web-server-racket-hello-world

[ysangkok]

Added packages, starting with the leaves of the dependency tree:

cont

Double-barreled continuations. Used in the pg, http2, web-server-racket packages.

buf-conn

Buffered connection (as in TCP). Based on continuations. Let's you only read the amount of bytes you want.

pg-types

Data types for PostgreSQL clients. Used in the pg and http2 packages.

http2

Continuation based HTTP2 server. No IO. Used in web-server-racket.

pg

Continuation based PostgreSQL client. No IO use. Used in web-server-racket.

racket-tcp

Thin bindings to the racket/tcp library. Supports concurrency using the Racket custodian.

web-server-racket

HTTP2 server with PostgreSQL access. See usage example in web-server-racket-hello-world. Only supports Racket due to reliance on the racket-tcp library.

web-server-racket-hello-world

Example demo web server that computes 1+1 on a PostgreSQL server and returns the result over HTTP2. Racket only.

Failure seems lsp related. I'll pull again once main passes CI

[stefan-hoeck]

I just started a re-run. Let's see if this works now.

[stefan-hoeck]

Could you please rebase this to be up to date with the current HEAD? We need the new split-up version of lsp from HEAD in order for the CI to succeed.

[ysangkok]

@stefan-hoeck I don't have access to a CLi right now and I don't think I can rebase using the web interface. But it should be possible to squash merge and achieve the same result.

[ysangkok]

@stefan-hoeck I have now rebased as requested!

[stefan-hoeck]

Thanks for these additions!
