rikardfalkeborn 869e4ba6ab Add check for return value of boolean function (#1451)
* Add check for return value of boolean function

The rule for converting an integer to a boolean is that 0 is mapped to
false and everything else is mapped to true. There is nothing wrong with
the following code (according to the standards):

    bool f()
    {
        return -1;
    }

and neither gcc nor clang will warn about it. However, it's a bit
confusing. This commit adds a check that warns when a value other than 0
or 1 is returned from a boolean function (similar to the existing check
that functions with boolean arguments are only passed 0 or 1). Since the
code is perfectly legal, set the severity to "Style".

* Use early continue and remove some braces

* Add testcase with multiple returns

* Avoid null pointer dereference in case of return without operand

* Skip lambdas

Add TODO-test cases that shows FPs when the return type of lambdas are
specified explicitly (this is a problem with findLambdaEndToken).

* Enable testcases

Daniel Marjamäki ab08801dc4 Remove header tests from testconstructors, because they were invalid (using preprocessor directive)
The checker does not care if it's a header or source file. So I guess these tests were added to test

testing for it in simplecpp.. I will add some testing for #line asap.

IOBYTE 0763fdbfad Copy template default argument values from forward declaration to declaration. (#1447)
It is possible to define default template parameter values in forward
declarations and not define any in the actual declaration.  Cppcheck
ignores forward declarations and only uses the default values in the
actual declaration so default values in forward declarations are copied
to the actual declaration when necessary.

rikardfalkeborn 613dc19b68 #4241: Check for address of single character passed as string (#1381)
* #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.

IOBYTE 0a30768b59 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.

rikardfalkeborn 75caf8e4de 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

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.

rikardfalkeborn 5e120b567c 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.
