[RFC PATCH-for-10.1 00/19] qemu: Introduce TargetInfo API (for single binary)

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Hi,

At this point this series is mostly a draft for Pierrick.
It implement his idea of a per-binary structure containing
all target-specific information, exposing them via a
target-agnostic API. Commits are barely commented, since
I'd rather get feedback before pursuing further.

Available here, based on tcg-next:
https://gitlab.com/philmd/qemu/-/tags/single-binary-target-info-api-rfc-v1

Another series will follow with the ARM implementation.

Regards,

Phil.
