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

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.

Set struct size cutoff in passedByValue check to 2*sizeof_pointer
...
Struct arguments are either pushed to the stack or passed in the
registers. Since both methods operate on machine words it is logical to
tie the maximum size of a struct argument that doesn't trigger
passedByValue diagnostic to the size of the machine word.
Also guessed size of STL classes is set to 3*sizeof_pointer, this better
represents reality and ensures that structs containing them will still
trigger passedByValue.

Add internal check that checks for redundant non-nullness checks in Token::(simple)Match checks.
...
In code like
if (tok && Token::simpleMatch(tok, "bla")) {}
or
if (tok->previous() && Token::Match(tok->previous(), "foo")) {},
the first check is redundant because Token::(simple)Match already checks if the argument token is null.
