There are some good cleanups in here, thanks! It is hard to review due
to the number/size of changes. I put it into a test run on the
autobuilder and it failed:

https://autobuilder.yocto.io/builders/nightly-musl/builds/1220/steps/Running%20Sanity%20Tests/logs/stdio

The rest of the builds have't gotten this far yet but I suspect we'll
see further similar failures and these will need to be fixed before we
can consider merging the patches.

Cheers,

Richard
