A (very) slight speed improvement for iterating over bytes (#21705) 
My mentee @xvxvxvxvxv noticed that iterating over array.array is
slightly faster than iterating over bytes.  Looking at the source I
observed that arrayiter_next() calls `getitem(ao, it->index++)` wheras
striter_next() uses the idiom (paraphrased)

    item = PyLong_FromLong(seq->ob_sval[it->it_index]);
    if (item != NULL)
        ++it->it_next;
    return item;

I'm not 100% sure but I think that the second version has fewer
opportunity for the CPU to overlap the `index++` operation with the
rest of the code (which in both cases involves a call).  So here I am
optimistically incrementing the index -- if the PyLong_FromLong() call
fails, this will leave the iterator pointing at the next byte, but
honestly I doubt that anyone would seriously consider resuming use of
the iterator after that kind of failure (it would have to be a
MemoryError).  And the author of arrayiter_next() made the same
consideration (or never ever gave it a thought :-).

With this, a loop like

    for _ in b: pass

is now slightly *faster* than the same thing over an equivalent array,
rather than slightly *slower* (in both cases a few percent).

closes bpo-38156: Always handle interrupts in PyOS_StdioReadline. (GH-21569) 
This consolidates the handling of my_fgets return values, so that interrupts are always handled, even if they come after EOF.

 I believe PyOS_StdioReadline is still buggy in that I/O errors will not result in a proper Python exception being set. However, that is a separate issue.
