handling `jupyter-org-request' objects.

A `jupyter-kernel-client' defers most of its message sending, receiving, and
message processing to a subprocess which sends its messages to the kernel
through zmq sockets and polls for any messages to received from the kernel.
This commit generalizes this by introducing a new `jupyter-ioloop` type which
encapsulates the subprocess and the code necessary to build up the function
that does the work of communicating with a kernel in the subprocess
environment.

Previously pending requests were associated with the ioloop process itself, but
pending requests are a particular feature of the client and used only for a
client's purpose.
* Define `jupyter-load-language-support` which takes a client and loads the
language support definitions of the client's kernel language.
* Call `jupyter-load-language-support` when initializing a REPL buffer in
`jupyter-repl-mode`. Note this also takes care of loading the kernel support
for a `jupyter-org-client' since a REPL buffer is setup before evaluating any
`org-mode` source code blocks.
* Move language specific methods to their own files named `jupyter-LANGUAGE.el`
If `kill-emacs` is called while the kernel process or client channel processes
are still alive, the process sentinels do not run and thus the cleanup of the
clients and managers does not happen. Thus we need to explicitly do this
cleanup when `kill-emacs` is called.
This replaces the behavior of the `:input-reply` message
type. A kernel sends an `:input-request` to the frontend
and the client sends an `:input-reply`.
* Define the `jupyter-lang` method context specializer that
specializes against the kernel language of
`jupyter-current-client`
* Remove the kernel support API
* Replace the kernel support API with methods that can be
specialized using the `jupyter-lang` context specializer.
