strdup() allocates the string length plus one for a terminating null
character. Add one to compensate for this.
Fixes false positive buffer out of bounds on code like this:
void f() {
const char *a = "abcd";
char * b = strdup(a);
printf("%c", b[4]); // prints the terminating null character
free(b);
}
Also, add a testcase for valueFlowDynamicBufferSize() and add tests for
strdup(), malloc() and calloc().
* Add non const version of some methods of Token
The aim is to reduce the (ab)use of const_cast.
* Cleanup some more const_cast in valueflow
* Remove useless const_cast
* Remove some const_cast from templatesimplifier
* Remove some const_cast from valueflow
* template simplifier: add 2 new template parameter simplifications
int{} -> 0
decltype(int{}) -> int
This fixes reduced test cases like #9153. I'm not sure they will help
real world code that much.
It was necessary to increase the pass count to 4 to get #9153 completly
simplified.
* relax decltype(type{}) simplification to any type
* Add cmd parameter for choosing between C90 and C99
Misra specifies different requirements to the uniqueness of
macros/enums/variables depending on what C standard
that's being used.
* Add standards configuration to each dump file
Read standards config from misra addon to decide what rules to use.
* Posix as standard setting should be deprecated. Don't include this in the xml
* Rewritten to use a switch
Refactored simplifyTemplateAliases to iterate over template type aliases
rather than instantiations. This fixed template type aliases that were
not templates.
Don't instantiate templates in template type aliases. They will get
instantiated once the type alias is instantiated. This required
increasing the template simplifier pass count to 3 so one of the
existing tests continued to work.
Specialized member classes declared outsize the class were not
recognized. This caused the the member class to be instantiated rather
than the specialized class. We already had a test for this but it was
wrong so it went unnoticed.
* CodeEditor Widget Styling
With profileration of Qt5 styling methods, problems with presentation
can occur when using cppcheck-gui and user choosen themes. With a dark
theme, a highlighted line in the CodeEditor appears with white text on
a light background or dark colors on a dark background.
Commit makes changes to enforce a default style on the Code Editor widget.
Mechanism is provided, if desired, where a user defined styling can
be provided to CodeEditor widget.

2nd commit - remove declarations in gui/codeeditorstyle.h to possibly
resolve appveyor window builds.
