[RFC PATCH 00/11] Bus cleanup for 22.11

[David Marchand]

This is a PoC for hiding the rte_bus object and mark associated API
as internal.

A good amount of the patches are preparation work on rte_bus.h,
rte_dev.h, rte_devargs.h and rte_eal.h headers, removing dependencies
between them. This is something I had in store for some time, maybe I
should have dropped it from the PoC, but I think those cleanups are
worth it in any case.

The last two patches do the actual job: add accessors and make the
rte_bus object opaque to non internal users.


Disclaimer: this series is a bit rushed (I brute forced compilation
tests in GHA so that it passes between patches, but there still may be
something broken...).
Not surprisingly, the ABI check in the CI is expected to fail.

Comments welcome.

I also hope we can do the same work on other generic objects
(rte_driver, rte_device), but this is another story.
