Feature: tracking remote branch with refspec

[lms-jk]

Disclaimer: I had to submit this patch on GitHub, because our company SMTP server mangles the messages.

This feature allows checking out a specific commit of a meta-layer while still tracking remote branches (see mailing-list for more info). It is only a proof-of-concept and probably not ready to merge.

I implemented your suggestions. Thanks for mirroring to the ML :)

Done - but there are still some todos:

• signed-off
• commit message for patch 1 at least

Absolutely, this patch exists only to start a discussion.

Just to link: current next containing https://groups.google.com/g/kas-devel/c/WmaNMfIDiMU/m/RxsnS1__EQAJ now allows to define both a concrete commit ID while still checking this out into a remote-tracking branch. Please check if that fulfills your needs.

The changes look good. Explicit keys for commits and branches are easier to understand and reduce complexity compared to the initial extension of the "refspec" key I came up with. :+1:

Perfect, then let's close this one.
