[PATCH 0/3] rust: doctest: unify with other kunit tests

[Gary Guo]

Currently in Rust, kunit tests are handled with `kunit_tests`, while the
doctests generate a lot `extern "C"` functions and invoke them through a
generated C wrapper.

This is currently needed because of the special treatment of file name and
line numbers from doctests. Convert them to override `file!()` and
`line!()` macro instead, and use them inside `kunit_assert!`.

With this it is possible to just generate `#[kunit_tests]` and `#[test]`
for doctests.
