* #4241 : Check for address of single character passed as string
Add a check that address of a single character is not passed as argument
to argument marked as strings (using strz). The check does not warn if
the address of a character with known value '\0'.
Since ValueFlow currently does not handle global constants (see #7597 ),
do not warn if the variable is global to avoid FPs when the address of
a global variable assigned to '\0' is passed to a function expecting a
string.
Remove comment in docs saying strz is unused.
* Change asdf to Hello world
* Add test of address to first element in string
* Add error reporting function to getErrorMessages
* Fix strings in test

Fixed #8693 (Template specialization: Constructor detected as normal … ( #1418 )
...
* Fixed #8693 (Template specialization: Constructor detected as normal function (functionStatic error))
Refactor template simplifier to remove the existing full specialization
function expandSpecialized and allow full specializations to use the
existing function expandTemplate. The function expandTemplate was
modified to either expand the template like it originally did by copying
it or to modify the template in place. Both instantiated and
uninstantiated full specializations are modified in place. This also
fixes #8692 and probably other related tickets as well.
The function simplifyTemplates now tries twice to simplify templates so
more templates can be simplified. We should try as many times as
necessary to find all possible templates. We can't do that now because
uninstantiated templates are left unchanged. It is relatively straight
forward to have the new code also expand in place uninstantiated
templates with their symbolic types but namespaces are not handled
properly (ticket #8671 ) and it would introduce regressions.
* Fix travis warnings.

Fix #8230 : FP unknown evaluation order on comma expression in while clause ( #1415 )
...
The while part of a do-while loop looks almost like a function call, so
extend the check for function calls to ignore while-statements.
Note that there was only an FP when checking c-code, since the check is
disabled for c++-code. Therefore, make sure the test cases are run on a
c-file.

isVariableDeclaration: Handle pointer to const pointer ( #1395 )

isVariableDeclaration did not handle pointer to const pointer, or
pointer to volatile pointer. This resulted in FPs in examples like the
following:
class Fred {
public:
const char *const *data;
const char *const *getData() { return data; };
}
where cppcheck would say getData could be static, since it didn't
recognize const char *const *data as a variable declaration.
