Fixed #5982 (Add xml dump)
xml dump: remove duplicate attribute
xml dump: output a <variables> with all variables
xml dump: Fixed segfault when dumping symboldatabase variables
xml dump: fixed some minor issues in symboldatabase dump
xml dump: fixed some bad xml output in the token list dump
ValueFlow: Small cleanups
TemplateSimplifier: Fixed crash caused by null pointer dereference. I don't have a testcase. But the code is suspicious, in the loop we check if tok3 is null and then in the loop head we call tok3->next().

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.
