Also correct a doc string and insert commentary. This fixes
bug#74052.
* lisp/emacs-lisp/edebug.el
(edebug--match-&-spec-op <&interpose>): Correct and complete
the doc string, which now says MUST call exactly once, and
documents the return values of FUN, PF and
edebug--match-&-spec-op. Also remove an unneeded `(...)
construct.
* lisp/emacs-lisp/pcase.el (pcase--edebug-match-pat-args): Call
PF also for the main cases handled.
Change `function` so that when evaluating #'(lambda ...)
we return an object of type `interpreted-function` rather than
a list starting with one of `lambda` or `closure`.
The new type reuses the existing PVEC_CLOSURE (nee PVEC_COMPILED)
tag and tries to align the corresponding elements:
- the arglist, the docstring, and the interactive-form go in the
same slots as for byte-code functions.
- the body of the function goes in the slot used for the bytecode string.
- the lexical context goes in the slot used for the constants of
bytecoded functions.
The first point above means that `help-function-arglist`,
`documentation`, and `interactive-form`s don't need to
distinguish interpreted and bytecode functions any more.
Main benefits of the change:
- We can now reliably distinguish a list from a function value.
- `cl-defmethod` can dispatch on `interactive-function` and `closure`.
Dispatch on `function` also works now for interpreted functions but still
won't work for functions represented as lists or as symbols, of course.
- Function values are now self-evaluating. That was alrready the case
when byte-compiled, but not when interpreted since
(eval '(closure ...)) signals a void-function error.
That also avoids false-positive warnings about "don't quote your lambdas"
when doing things like `(mapcar ',func ...)`.

* lisp/emacs-lisp/cl-preloaded.el (closure): New type.
(byte-code-function): Add it as a parent.
(interpreted-function): Adjust parent (the type itself was already
added earlier by accident).
* lisp/emacs-lisp/bytecomp.el (byte-compile--reify-function): Adjust to
new representation.
(byte-compile): Use `interpreted-function-p`.
* lisp/emacs-lisp/byte-opt.el (byte-compile-inline-expand): Adjust to

function values are lists. Reword "self-quoting" to reflect the
fact that #' doesn't return the exact same object. Update examples
with the new shape of the return value.

* doc/lispref/control.texi (Handling Errors): Update examples to reflect

Rework the code that "cleans" the backtrace for `edebug-pop-to-backtrace`.
The main changes are the following:
- Strip instrumentation from "everywhere" rather than trying to limit the
effect to "code" and leave "data" untouched. This is a worthy
goal, but it is quite difficult to do since code contains data
(so we ended up touching data anyway) and data can also
contain code.
The risk of accidentally removing something because it happens
to look like instrumentation is very low, whereas it was very common
for instrumentation to remain in the backtrace.
- Use a global hash-table to remember the work done, instead of
using separate hash-table for each element. By using a weak
hash-table we avoid the risk of leaks, and save a lot of work
since there's often a lot of subexpressions that appear
several times in the backtrace.
* lisp/emacs-lisp/edebug.el (edebug-make-enter-wrapper): Tweak code
layout so the comments are more clear.
(edebug-unwrap): Remove redundant patterns for `closure` and `lambda`.
Add `:closure-dont-trim-context` to the `edebug-enter` pattern,
so it also gets removed (this should have been done in commit
750bc57cbb).
(edebug--unwrap-cache): New var.
(edebug-unwrap*): Use it.
(edebug--unwrap1): Delete function. Merged into `edebug-unwrap*`.
Also apply unwrapping to the contents of byte-code functions since they
can refer to lambda expressions captured by the closure.
(edebug--symbol-prefixed-p): Rename from
`edebug--symbol-not-prefixed-p` and adjust meaning accordingly.
(edebug--strip-instrumentation): Adjust accordingly and simplify
a bit by unifying the "lambda" case and the "everything else" case.
(edebug--unwrap-frame): Use `cl-callf` and unwrap arguments even if
they've already been evaluated.

This fixes bug#65620. The error thrown up to now was "Void
function edebug-after". This has been replaced by "Invalid
call to `edebug-before'. Is the edebug spec for `foo'
correct?".
* lisp/emacs-lisp/edebug.el (edebug-b/a-error): New function
which throws the new friendlier error message.

in bae2cfe63c, because this leads to errors in a common (and
recommended) use case (bug#47516).
Don't bind `load-read-function` to nil but to its actual default value.
Actually, I'm not sure it's worth the trouble rebinding this var, but
if we do, then we should bind it to a valid value rather than to nil.

if needed.
Edebug doesn't deal well with backtracking out of definitions, see
Bug#41988. Rather than trying to support this rare situation (e.g. by
implementing a multipass parser), prevent it by adding an implicit

backtracking when hitting a &define keyword.

making it an `:around` advice.
