Subject: [PATCH v2 00/19] rust: replace `kernel::c_str!` with C-Strings

This series depends on step 3[0] which depends on steps 2a[1] and 2b[2]
which both depend on step 1[3].

This series also has a minor merge conflict with a small change[4] that
was taken through driver-core-testing. This series is marked as
depending on that change; as such it contains the post-conflict patch.

Subsystem maintainers: I would appreciate your `Acked-by`s so that this
can be taken through Miguel's tree (where the previous series must go).
