As mentioned in the original OClosure commit, OClosures (ab)use the
bytecode's docstring slot to hold the OClosure's type. This currently
prevents OClosures from having their own docstring.
Introduce a new generic function `function-documentation` to fetch the
docstring of a function, which can then be implemented in various
different ways depending on the OClosure's type.
* lisp/simple.el (function-documentation): New generic function.
(bad-package-check): Strength-reduce `eval` to `symbol-value`.
* src/doc.c (Fdocumentation): Use it.
* lisp/emacs-lisp/oclosure.el (oclosure--accessor-docstring): New function.
* test/lisp/emacs-lisp/oclosure-tests.el (oclosure-test):
Add test for accessor's docstrings.

treatment, i.e. only interpolating scrolls coming from mice and
not touchpads inside pixel-scroll-precision-mode.

recorded device.

* src/xterm.c (x_init_master_valuators): Record the device's
name.

the mouse ended up in the source frame.

We here just add the new type. It is not fully self-contained.
It requires cooperation from `cconv.el` on the one hand, and it
hijacks the docstring info to hold the type of OClosure objects.
This does imply that OClosures can't have docstrings, tho this
limitation will be lifted in subsequent patches.
