v20240817-0003 and 0004.

(This is a repeat of the same comment as in previous reviews, but lots
more functions seem affected now)

IIUC, the LR code tries to follow function naming conventions (e.g.
CamelCase/snake_case for exposed/static functions respectively),
intended to make the code more readable. But, this only works if the
conventions are followed.

Now, patches 0003 and 0004 are shuffling more and more functions
between modules while changing them from static to non-static (or vice
versa). So, the function name conventions are being violated many
times. IMO these functions ought to be renamed according to their new
modifiers to avoid the confusion caused by ignoring the name
conventions.
