[PATCH RFC 00/11] rust: add support for dynamic debug

[Thomas Weißschuh]

Add the Rust infrastructure to integrate with the dynamic debug
infrastructure.

Static keys are not used for now, as the full bindings are missing
for those. A follow-up series will add that.
Also custom classes are not supported yet, but could be added on top.

Patches 1-4: Generic Rust preparation patches.
Patches 5-7: C dynamic debug preparation patches.
Patches 8: Rust Dynamic debug infrastructure.
Patches 9-11: Rust Dynamic debug enablement.
