[issue16638] support multi-line docstring signatures in IDLE calltips

[Serhiy Storchaka]

Here is a patch moved from issue16629.

I think this is a bugfix, because current behavior is wrong. Many functions (i.e. int, str, list, dict) have multiline signatures and IDLE shows only first line in a tip. I.e. "int(x=0) -> integer" showed for int(), but int() accepts up to two arguments. This is a regression comparing with times when the signature was oneline.
