ci-scripts 3.0 release: Windows on Travis

[Ralph Lange via Tech-talk <tech-talk at aps.anl.gov>]

Dear all,

Release 3.0 of the ci-scripts module is available on GitHub.

https://github.com/epics-base/ci-scripts/releases/tag/v3.0.0

The implementation is now a single Python script (based on the AppVeyor script from v2.x) and supports native Windows builds on Travis, with five parallel runners and caching of built dependencies.

As part of the consolidation, configuration has changed slightly, and both Travis and AppVeyor configuration files have to be changed when migrating to v3.x - see the new Migration Hints section in the README for more details.

Since ci-scripts is used as a git submodule, your modules always use a fixed version of ci-scripts and you can freely choose the moment to do the migration.

Thanks a lot to Torsten Bögershausen, Mark Rivers and Michael Davidsaver for their help and patience with beta testing this release.

Cheers,
~Ralph

ps. Next on the list: support for the GitHub Actions service.
