; Rename internal variable in erc-fill

* lisp/erc/erc-fill.el (erc--fill-wrap-scrolltobottom-exempt-p):
Rename to `erc-fill--wrap-scrolltobottom-exempt-p' so prefix matches
library and feature.
(erc-fill--wrap-ensure-dependencies): Update variable name.
* lisp/erc/erc-truncate.el (erc-max-buffer-size): Don't mention
`erc-insert-post-hook' in doc string because truncation now happens
elsewhere.
(erc-truncate-buffer-to-size): Update obsolete comment that describes
pre-5.5/Emacs 29 behavior.
* test/lisp/erc/erc-fill-tests.el (erc-fill-tests--wrap-populate):
Update variable name.
* test/lisp/erc/resources/erc-d/erc-d-tests.el
(erc-d-u--canned-load-dialog--basic)
(erc-d-u--canned-load-dialog--intermingled)
(erc-d-u--rewrite-for-slow-mo): Timeouts.
* test/lisp/erc/resources/erc-d/resources/basic.eld: Timeouts.
* test/lisp/erc/resources/erc-scenarios-common.el
(erc-scenarios-common--make-bindings): Use updated variable name.
