#6181 Drop redundantGetAndSetUserId. Ensure (style-) warnings are issued if setuid()/getuid() and some related functions are ignored. Move strdupa()/strndupa() from posix.cfg to gnu.cfg

Removed standalone check CheckOther::checkDoubleFree(), integrated (most of) the functionality into CheckLeakAutoVar. Added support for new/delete to checkLeakAutoVar.

Add new "style" check to catch redundant pointer operations
...
Doing "&*some_ptr_var" is redundant and might be the remainder
of a refactoring. Warnings for expanded macros are excluded though:
They are often used with and without pointers and
do something like this: "func(&(*macroarg))".
The new check is fully AST based and was given
strong false positive testing on a large code base.

Fixed false positives about strdupa() / strndupa() memleak
...
strdupa() / strndupa() allocates memory on the stack using alloca().
This memory is freed automatically once the current function is left.
