This is a breaking change but adds another level of safety to ensure
the file descriptor we receive is valid. Additionally, this allows
aya to internally easily duplicate this file descriptor using std
library methods instead of manually calling `dup` which doesn't
duplicate with the CLOSE_ON_EXEC flag that is standard pratice to
avoid leaking the file descriptor when exec'ing.
This commit reveals but does not address a file descriptor leak in
LircLink2::query. This function returns a list of `LircLink`s where
each of them have a program file descriptor that is not going to be
closed. This commit does not add this leak; it merely makes it louder
in the code.
Wrap verifier logs in a newtype whose `Debug` impl emits unescaped
newlines. This improves ergonomics in tests where we `Result::unwrap()`
those load errors; when these fail today they emit the errors with
newlines escaped, making them incredibly difficult to read.
Adds cargo-public-api. This allows for public API changes to get caught
in CI, requiring new changes to be "blessed" by using:
cargo xtask public-api --bless
When this file is changed for aya, Alessandro will need to review the PR.
