Previously it was hard to step through the code whenever messages were
coming in live from a kernel due to the asynchronous nature of
handling process output in Emacs.
- Add a `message-publisher` slot to `jupyter-request`, set when
sending a request.
- `*-request` functions now return a delayed request value instead of
a request. Update call sites.
- Add the functions `jupyter-messages`, `jupyter-idle`,
`jupyter-message-subscribed` and `jupyter-client-subscribed`.
- Move client subscription to a request's messages to
`jupyter-client-subscribed`.
- Request callbacks are now added via `jupyter-message-subscribed`.
- Reduce usage of callbacks in favor of searching `jupyter-messages`
where appropriate.
- Update tests
* jupyter-base.el (jupyter-read-connection): Validate connection info.
* jupyter-repl.el (jupyter--connection-info): Remove
(jupyter-connect-repl): Only allow a file path as the first argument of
`jupyter-connect-repl`. Update doc. No need to update any callers
since the other form of the argument was not used.

It is replaced with `jupyter-map-mime-bundle` which is a function.
* jupyter-base.el (jupyter-loop-over-mime): Remove.
(jupyter-map-mime-bundle): New function. Update call sites of the
removed function, with calls to this function.
(jupyter-normalize-data): Return a mime bundle, a property list with
:data and :metadata keys. Update all callers.
* jupyter-mime.el (jupyter-insert): Updated to take into account the
previously mentioned changes.
* jupyter-org-client.el (jupyter-org-result): Ditto.
* test/jupyter-test.el (jupyter-loop-over-mime): Rename to
`jupyter-map-mime-bundle` and update the test to consider it.
Converting to lowercase was done arbitrarily. So that one could write
`(jupyter-lang wolfram-language)` instead of
`(jupyter-lang Wolfram-Language)`.

Speeds up the line count test associated with
`jupyter-eval-short-result-max-lines` by an order of magnitude for somewhat
large strings. The byte compiled versions are not that different.
Since `jupyter-current-client` is a buffer local variable, its value inside the
display buffer is always `nil` when we usually want it to take on the value it
has before this macro is called.
If method arguments are not named it gives rise to errors like
`Args out of range: "", 0`
that originate in `help-function-arglist` when calling `describe-function` on
those methods.
This refactor implements a new class hierarchy to manage the lifetime of a
Jupyter kernel. The first node in this hierarchy is the
`jupyter-kernel-lifetime` class which defines a set of methods to manage the
lifetime of a kernel. An object that inherits from `jupyter-kernel-lifetime` is
stating that it has an association with a kernel and can be used to manage the
lifetime of the associated kernel.
The `jupyter-meta-kernel` class inherits from `jupyter-kernel-lifetime` and
mainly defines a `spec` slot used to hold the `kernelspec` from which a command
can be constructed to start a kernel and a `session` slot used to hold the
`jupyter-session` object that clients can use to establish communication with a
kernel once its live. Concrete classes that actually launch kernels are
intended to inherit from this class and use its slots.
`jupyter-kernel-process` manages the lifetime of a kernel started as a process
using the function `start-file-process`, `jupyter-command-kernel` calls the
`jupyter kernel` shell command to start a kernel, finally `jupyter-spec-kernel`
uses the `spec` slot to construct a shell command to start a kernel.
A `jupyter-kernel-manager` now consists of a `kernel` slot that holds a
`jupyter-meta-kernel` and a `control-channel` slot and inherits from
`jupyter-kernel-lifetime`. The `jupyter-kernel-lifetime` methods of the manager
just defer to those of `kernel` while also taking into account the
`control-channel`.
