chg: usr: Enforce bounds of multiple configuration options

The configuration options `edns-version`, `edns-udp-size`,
`max-udp-size`, `no-cookie-udp-size` and `padding` now enforce
boundaries. The configuration (including when using `named-checkconf`)
now fails if those options are set out of range.

Merge branch 'colin/multiple-options-strict-boundaries' into 'main'
