Re: new utility function getcpy_len()

The question this patch raises for me is,
Where should the new function getcpy_len() go?

I found it useful only in imaptest.c, so perhaps it should be
added there.

But it is a variant of the existing getcpy() function, and it
seems useful enough that looking more might find more uses for
it, so perhaps it belongs in getcpy.c.

Opinions?
