Detect -> accesses on uninitialized pointers
Sign conversion: Improved check. When its not explicit that 'int' variable is signed but it can have negative values, assume its signed
Fixed #6165 (Remove old checkUnsignedDivision checker that uses neither AST nor ValueFlow. The CheckType::checkSignConversion should be much more accurate)
Merge partially duplicate patterns

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.

[ci skip]
PEP8 fixes.
