I don't have a Trac account, so there is no ticket for this; the details are below. Feel free to create one and I'll add it to the title.

Passing an allocated pointer to a function configured as <use> still gives a --check-library message:

use.cfg:

<memory>
  <alloc>myalloc</alloc>
  <use>set_data</use>
  <dealloc>myfree</dealloc>
</memory>
<function name="myalloc"><noreturn>false</noreturn><arg nr="1"/></function>
<function name="set_data"><noreturn>false</noreturn><arg nr="1"/></function>

use.c:

void f(void)
{
    char *p = myalloc(10);
    set_data(p);
}

$ cppcheck --check-library --library=use.cfg use.c
use.c:5:1: warning: --check-library: Function set_data() should have <use>/<leak-ignore> configuration [checkLibraryUseIgnore]

The cfg reference says <use> exists to silence exactly this message, but CheckLeakAutoVarImpl::configurationInfo() only took <leak-ignore/> into account. It now skips functions that have <use> as well. The leak analysis itself is unchanged.

Test: TestLeakAutoVar::configurationUse; it fails without the change.
