`point-at-eol` is obsolete

[bdarcus]

I just noticed this with my Emacs 29 install:

⛔ Warning (comp): parsebib.el:634:21: Warning: ‘point-at-eol’ is an obsolete function (as of 29.1); use ‘line-end-position’ or ‘pos-eol’ instead.

Looking a bit, that second alternative is new, but the other is not.

Yeah, now that I think of it, point-at-eol is a weird name. Will need to unlearn. 😄
