[PATCH 0/8] rust: pin-init: various cleanups to prepare for self-reference

[Gary Guo <gary@garyguo.net>]

Pin-init self reference is going to be a big feature, touching various
places in pin_data and init macros. Do some various cleanups to tidy up the
macro codebase, so the feature can land without much refactoring.

Details in commits.
