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.

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.

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.
