Merge branch 'ps/rust-balloon'

Dip our toes a bit to (optionally) use Rust implemented helper
called from our C code.

* ps/rust-balloon:
  ci: enable Rust for breaking-changes jobs
  ci: convert "pedantic" job into full build with breaking changes
  BreakingChanges: announce Rust becoming mandatory
  varint: reimplement as test balloon for Rust
  varint: use explicit width for integers
  help: report on whether or not Rust is enabled
  Makefile: introduce infrastructure to build internal Rust library
  Makefile: reorder sources after includes
  meson: add infrastructure to build internal Rust library
