Merge branch 'mp-202102-gwenbuild'

gwenbuild now works with AqBanking and especially with AqFinance. Needs more refinement but works.

gwenbuild: Added help string.

gwenbuild: Added command "clean" (-c).

This command deletes all generated files (except config.h, that is).

gwenbuild: Increased verbosity.

Dependency tracking now uses DBG_INFO to allow for debugging of issues.

gwenbuild: Added module for CXX apps.

Probably not needed as gcc seems to figure out when to link-in c++ code.

gwenbuild: Improved install command.

gwenbuild: Implemented install.

syncio: Add function GWEN_SyncIo_Helper_CopyFile().

gwenbuild: Prepared command "-i": Install.

gwenbuild: Fixed dependency tracking.

Only check dependencies and file dates when running the first sub command.
If it is decided that a rebuild is needed all subsequent sub commands need
to be executed in any case without further checking.

gwenbuild: Added command "-r": Repeat setup.

This command repeats the setup process using the same arguments given to the
last full setup.

gwenbuild: Write install file list. Promoted some functions to API functions.

gwenbuild: Allow for flag "GENERATED" to be specified in "<data>".

gwenbuild: Added support for loadable modules.

gwenbuild: Fixed dependecy handling.

gwenbuild: Some ideas for next changes.

gwenbuild: Disable unlink for now, will work on it later.

gwenbuild: Add flags to delete output files before build.

No longer need a "rm" subcommand which might fail and print a confusing
error message.

gwenbuild: Added entry to TODO chapter.

gwenbuild: Only call GWEN_XMLNode_SetCharValue() with nonempty values.

gwenbuild: Add files from <writeFile> to project file list.

This makes sure that gwenbuild knows that the written file is generated.
