Kimmo Varis 9627b667a1 Move simplifyPath method from FileLister to Path class.
simplifyPath() "fits" better to Path class conceptually. It handles
paths, not lists them. Also this way we get rid of few unneeded
dependencies to FileLister class.

    straight after creation.

    Only checks for misused scope objects within functions.

    Optimised isIdentifierObjectType() by memoizing.

Pete Johns c6acdccfa0 Fixed #1132 (Detection of misused scope objects)
Emits error in the form:

    [useless_lock.cpp:18]: (error) instance of "Lock" object destroyed immediately

...if an instance of a class or struct is unnamed and therefore destroyed
straight after creation.

Removed "internal error" from token.cpp, since in this case varid would be NULL.

Pete Johns 6a52538a9a Fixed #1949: assert() hides memory leaks
Added separate unit-test (trac1949), initially broken to highlight the error and added "assert" to call_func_white_list.

Left TestMemleakInFunction::call_func() as is, as this wouldn't highlight the actual problem.
