Some of the stream handling functions are modeled in StreamChecker.
These are now added to StdLibraryFunctionsChecker where additional
checks are performed on these functions. This includes setting of
'errno' related state. In this way the errno state is set for these
functions (almost) completely in StdLibraryFunctionsChecker.
The two checkers work together and 'apiModeling.StdCLibraryFunctions'
and its 'ModelPOSIX=true' option should be now a dependency of
checker 'alpha.unix.Stream'.
