Fix #8327 (Memleak with mmap return value check) (#2864) 
Also fix a broken test case related to checking the return value -1
where socket was not defined in the library used in the tests.

This was tested running test-my-pr with 500 packages. The difference was
six fewer FPs.

Library: Enhance minsize configuration and allow simple values. (#1736) 
Some POSIX and Windows functions require buffers of at least some
specific size. This is now possible to configure via for example this
minsize configuration: `<minsize type="value" value="26"/>`.
The range for valid buffer size values is 1 to LLONG_MAX

b78d714037 posix.cfg: access(): Removed redundant configuration, added tests (#1048) 
I intentionally removed the second access() configuraion because it was
missing the use-retval attribute. But calling access() without using the
return value is absolutely senseless.
I added tests to posix.c to verify the correct configuration of
access().

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
