[libusb] Use github actions instead of Travis-CI?

[Ludovic R. <lud...@gm...>]

Hello,

Travis-CI is not usable any more.
The latest libusb build was 7 months ago:
https://travis-ci.org/github/libusb/libusb/builds

I propose to drop support of Travis-CI and use Github Actions instead.
https://github.com/features/actions

What do you think?

Bye
