Lazily convert numeric strings to Lisp numbers in Eshell

Bug#72272

(cherry picked from commit 7cbca90569472af5643905fca5b7ab2dea67f876)

Rewrite Speedbar expansion for all descendants (bug#73533)

Rewrite 'speedbar-expand-line-descendants' to avoid getting into
an infinite loop by reaching max-lisp-eval-depth.  The new
method avoids querying and displaying information for every
movement, instead using a single message to indicate that
expansion is in progress, and so is significantly faster.  The
narrowing per item introduced by the fix for bug#35014 is
removed because it prevented expanded descendant items when the
top-level item was already expanded.
* lisp/speedbar.el (speedbar--get-line-indent-level): New
function to return the indentation level of the current line.
(speedbar-expand-line-descendants): Use simpler line motion and
no recursion.  Output messages indicating when expansion is in
progress and when it is completed.  Fix expansion of descendants
where the top-level item was already expanded.

* lisp/erc/erc.el (erc-modules): Remove autoload cookie because it

erc-modules", which was added in ERC 5.6 and Emacs 30.  The motivation

; Mark interactive Eshell output as such after inserting into the buffer

This avoids adding the "output" text properties to strings that may live
past the call to 'eshell-interactive-filter'.

(track-changes--after): Fix problem found in bug#73041

When calling `track-changes--before` (e.g. because of a missing
b-f-c or for some other reason), it sets `track-changes--before-end`
to the right value so we shouldn't increment it right after.
Also, we should update `track-changes--buffer-size` before
calling `track-changes--before` so it doesn't risk signaling
a spurious inconsistency.

* lisp/emacs-lisp/track-changes.el (track-changes--after):
Update `track-changes--buffer-size` earlier, and don't increment
`track-changes--before-end` when we call `track-changes--before`.

Improve correctness of Eshell sub-forms

This makes sure that we treat Eshell sub-forms (whether Lisp or command
forms) as values when appropriate, or as regular invocations.  This
requires a bit more explicit work, but helps to resolve some of the

statements.

Simplify creation of Eshell command forms

Previously, Eshell over-aggressively converted subcommands, which forced
