Raw Blame History

This is not among the normal patches as these changes are musl specific and
there is no way to easily conditionalize it in source for some of the changes.
Added by q66: runtime.h now uses libucontext_ prefixed APIs to allow build
with freestanding versions of libucontext
Souurce: Adélie Linux, q66
