    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.

Pete Johns afc6d4507d Removed static std::string.
which_test() doesn't have to calculate anything, could be inlined.

Just getting to grips with how the tokenizer behaves.
