R(ABI) dependency generation

[spotrh]

Equivalent to how Python handles ABI dependency, create and apply a R(ABI) dependency using the R major and minor version (but not the patch version). The Provides: R(ABI) will be set in R-core. This should prevent mismatched installations.

@spotrh Could you fix your commit message? The title of this PR makes sense as the title of the Git commit and makes it much more readable. 😄

[spotrh]

Done!

@spotrh I meant you should just add the title to the commit message, like so:

If you'd like it in Klingon, let me know. ;)

[Conan-Kudo]

Perfecto! 💯

If a release with this change could please make its way to rawhide, I can start working on the R 4.0.0 mass rebuild. :)

I'm okay with this, if you want to be doing rebuilds of everything. I left something like this out to avoid it as it didn't always seem necessary.

I don't think this can come to Rawhide just yet as it'd break every other build; maybe you want to build in a side tag?
