Stlye(9) strengthen statements on not using K&R function definitions

Greetings

I've posted a review https://reviews.freebsd.org/D35945 which strengths
statements about K&R definitions and declarations: don't use them. Most of
the K&R code has been removed from the tree (ufs being the last straggler).
Future versions of the C standard will remove the K&R definitions and
declaration syntax. clang 15 will whine about this construct.

The time is ripe to move to language that suggests an outright prohibition.
