[csolution] --update-rte has two functions - treat them separately

[ReinhardKeil]

The Problem To Be Solved

update-rte performs two functions:

• it generates constructed-files (RTE_Components.h, Pre_Include_Global.h, etc.)
• it copies configuration files to the RTE folder

I believe these two features should be split. Reasons:

• When configuration files are forgotten, also the user settings for components are lost. Just copy the original files from packs may therefore result in errors.
• constructed-files are not user modifiable, they can be regenerated when missing without introducing problems.

The issue becomes apparent when using uv2csolution and folder names are changing due to CMake restrictions (no - in folder names).

[jkrech]

Is it acceptable to update constructed-files unconditionally (independently of --update-rte). A file will be written/updated only in case of differences between the files on disk and the newly generated files.

The config files are only being touched if --update-rte is active.

[ReinhardKeil]

Suggest to implement the following behavior regarding constructed files (RTE_Components.h, Pre_Include_Global.h, etc.).

Without option --update-rte: when constructed files are missing, csolution recreates the files, but issues a warning indicated which file was recreated.

With option --update-rte: the constructed files are updated.
