This change allows us to hanel cancel messages as they go into the queue, and
cancel messages that are ahead of them in the queue but not being processed yet.
This should reduce the amount of redundant work that we do when we are handling
a cancel storm.

We merge them into a single interface and support multiple of them rather than
just one.
This will allow us to stack handlers with different responsabilities and extract
some core logic (like tracing) out to a handler where it belongs.

This separates hides the wire structures, and then exposes a new Request
type to allow for it to carry advanced features.
It also embeds the connection into the request and changes the signature of the
handler to no longer require a separate Conn argument.

This changes the basic API of a jsonrpc2 connection to run the
read loop as a method rather than in a go routine launched in
the NewConn. This allows the handler to be created and bound
between construction and the read loop starting, which fixes
the race.

Delivering each message in a go routine turned out to be problematic, there are some messages
that must be fully processed before later messages are started, and there was no way to guarantee that.
We now push concurrence handling up to the higher level, this has the disadvantage of not being able to guarantee
we respond to call messages correctly, but its a small price to pay.
The LSP currently processes each message fully in order blocking the handler, while we still work on basic
functionality.
