windows library: Add config for some Local* functions (#1139)
Add configuration and tests for LocalAlloc, LocalFree and some other
Local* functions.
LocalReAlloc is currently not configured as an alloc/dealloc function
(like realloc is not configured in std.cfg), i am not sure how to
correctly configure it.

Add configuration for G_UNLIKELY and G_LIKELY to avoid syntax errors

Add test file to verify Gtk library configuration. Syntax check for the
test file is only done when Gtk+2.0 or Gtk+3.0 is found and working.

On Windows __wchar_t is a synonym for wchar_t, so an according define is
added.

wxwidgets: Fix syntax checking errors and warning (#1093)
wxDebugContext is only defined if wxUSE_DEBUG_CONTEXT is 1, so otherwise
just skip it for syntax checking because it will fail.
Change wxT to wxT_2 and add wxT_2 to the config to remove a warning
during syntax check and be more compatible with newer/older wxwidgets
versions.
Be more precise when replacing function like macros, fix redundant macro
definition for "_".

* Fix #8382 (Syntax error when scanning code with template and attribute)

This commit only addresses #8382. There are issues concerning which
versions of C++ should be supported and also generic C++ 14 attribute
support which can be revisited later.

* Remove all C++ style attributes.

Remove all C++ style attributes when C++ version is 11 or greater.
Rename simplify function to simplifyCPPAttributes.
Handle more cases of roreturn function attribute.

std library: Resolve two TODOs (#1074)
First resolved TODO in std.c is obsolete since the "res" variable is used later
and there is therefore no warning issued.
Second resolved TODO in std.c: A warning for uninit variables is issued by
cppcheck, so this check can be enabled. Since assert() has no noreturn configuration
(currently a useful configuration is not really possible, see ticket 8329) the
check-library message is suppressed.

syntax check is skipped.
wxwidgets.cpp: Fixed syntax, includes and added code so the syntax check
does not fail if some special features are not present.

wxwidgets library: Fix/Enhance cfg, add test file (#1082)
Add test file for wxwidgets configuration, fix found issues and enhance

Fix declarations in comments for wxLog* functions.
Merge the two wxTextFile::Create overloaded function configurations into
one that works for both now.
Removed use-retval attribute from wxBoxSizer::AddSpacer and
wxButton::SetDefault configuration since the functions have side effects
and there is no need to use the return value.

Jørgen Kvalsvik a61f21d1b6 Accept nested templates in tokenizer-simplify (#1070)
The following snippet triggerd the error:

template<typename DerivedT>
template<typename T>
auto ComposableParserImpl<DerivedT>::operator|( T const &other ) const -> Parser {
    return Parser() | static_cast<DerivedT const &>( *this ) | other;
}

Whenever simplifyFunctionParameters was called on a templated class'
templated member function (and probably any nested template), the
tokenizer would recognise it as a syntax error, assuming that return
type *must* come after a template<> token.

detection that would treat a case statement inside a switch that is not
a compound statement as garbage, but this is perfectly valid C++. This
construct is used in several libraries, i.e. Google Test.

Sebastian de7aa8f513 Fix #7504: posix: open() was twice in configuration file (#1032)
* Fix #7504: posix: open() was twice in configuration file

This fixes ticket #7504: Problems with the open function were not always
detected because the open function was twice in posix.cfg and only the
second configuration was used by cppcheck. Like suggested now only
one configuration is used and the third parameter has a default value
and is thereby optional.
use-retval has been removed to avoid duplicate warnings because the
alloc/dealloc configuration already warns about unused retval.
According tests to verify that open is configured
correctly now have been added to test/cfg/posix.c.

* posix.cfg: open(): Add TODO for use-retval configuration

IOBYTE cefb2131c7 Add support for simple c++ 11 type ailases like: using INT = int; (#1024)
* Add support for simple c++ 11 type ailases like: using INT = int;

Only types supported by ValueType are supported. Complex types like
function pointers are not supported. Template type aliases are not
supported.

* Fix crash when type in using type alias is simplified away.

This fixes a crash when size_t is replaced with unsigned long in: using
size_t = unsigned long; by the tokenizer.

This does not fix the problem where Tokenizer::simplifyPlatformTypes()
simplifies away size_t in other cases.  This is only a problem when the
new type is different from the platform type.
