c-c++ layer requires semantic layer

[herbertjones]

Unless semantic is enabled in dotspacemacs-configuration-layers, extra c-c++ packages do not appear to be added nor are they initialized correctly when other layers have enabled the packages. There is no error or warning accompanied by this behavior. Unless the semantic layer is enabled, c++ files will have missing functionality such as:

• yasnippet minor mode is not initialized
• srefactor keybindings are missing and the package is not installed

ycmd, however, still works if that layer is enabled.

Observed in develop 5b72221.

About semantic, it's intended since some people like it, some don't. Also, it's not specific to C++ so we separate it in its own layer.

@herbertjones If I understand well, only yasnippet has a wrong behavior right ?

[herbertjones]

Sounds like it. Perhaps it would be nicer for some kind of warning for users updating so that they know that they only need to add the semantic layer. Anyone finding the problem documented here in this github issue might be enough if the documentation for the layer is updated.

The c-c++ layer now contains notes about the semantic layer, and also about srefactor only available on emacs >= 24.4. yasnippet is working fine here even without the semantic layer.

All points being solved, I close this issue. Feel free to open a new issue in case of trouble ☺️
