Fix #9322: bsd.cfg, gnu.cfg: Fix FP for mmap when argument "fd" is -1 (#2306) 
In contrast to POSIX, GNU and BSD allow or even require the argument
"fd" to be set to -1 if MAP_ANONYMOUS or MAP_ANON is specified.

gnu.cfg: Define `__typeof__` as `typeof`, fix simplifyTypedef() (#2260) 
`__typeof__` is just an alternative keyword for `typeof`, see
https://gcc.gnu.org/onlinedocs/gcc/Typeof.html
Since `typeof` is handled in several checkers it makes sense to define
`__typeof__` as `typeof`.
Tokenizer::simplifyTypedef(): Use `typeof` instead of `__typeof__` to
be consistent with the rest of the code.

orbitcowboy aed5e17867 #9323, #9331: Moved configuration and tests to gnu and bsd. 2019-09-08 19:17:15 +02:00
versat 7ee36489f1 gnu.cfg: Add configuration for __builtin_memcpy() 
In case there is something like `#define memcpy __builtin_memcpy` in the
code our define for __builtin_memcpy does not work.
So the configuration for __builtin_memcpy is added as a fallback.

gnu.cfg: Add xfree() (#2051) 
It is hard to find good references, one that describes it a bit can
be found here:
https://manpages.ubuntu.com/manpages/bionic/man3/xmalloc.3pub.html

xfree() can be used instead of free().
A check, to verify that a memory leak is found if the memory allocated
via xmalloc() is not freed, has also been added.

Rikard Falkeborn e19068504d Configure xrealloc and adjust gnu memory functions (#2003) 
Remove <noreturn> tag, since the functions do not return unless there
was no error.

versat e0e262ae25 gnu.cfg: Use function configuration for `_()` instead of define. 
There can be preprocessor issues if the macro is used slightly different
or preprocessor conditions are used inside the string argument.
So now a function configuration with very few assumptions is used.
It is assumed that the function does return and has one parameter.
The same configuration is added for N_() since it works similar.

gnu.cfg: Add support for non-GNU _(string) macro. (#1726) 
As can be read here:
https://www.gnu.org/software/gettext//manual/html_node/Mark-Keywords.html
The _(str) macro is typically defined for a project to abbreviate the
gettext(str) call. Although this is not part of GNU it would enhance the
analysis. Cppcheck often does not know what _() is. In daca@home it is
reported thousands of times as a function without configuration.
