Libary: Fixed gcc warning -Wmissing-field-initializers
Revert my previous fix 28763fa020988ec938dae3d47c10be95c87de90e and suppress gcc false positive warnings.
ValueFlow: Fixed 'function call => calculation' value flow
Replaced static variable isCPP in Token (was not threadsafe):
- Encapsulate parameters passed through AST compiler functions in a struct
-> Reduces maintenance overhead when changing them
-> Contains parameter indicating if the file is C or C++
- Added eKeyword Token type (at the moment, only true for C++ keyword "delete", but should be set for other keywords as well)
Updated matchcompiler to latest changes

Move astyle options to astyle.ini.

This way we can use it in runastyle and runastyle.bat.

Settings changes:
* specify the files to exclude instead of specifying the files to style
* remove `--lineend` option
* keep the file's modified timestamp
* only show the styled files on the command output

Also change the astyle version check to only check for older not the exact version.

[ci skip]
Update runastyle.bat from MPC-HC.

It includes a check if astyle is present and for astyle's version.
Also, it allows drag and dropping files onto it to style them.
