gh-121650: Encode newlines in headers, and verify headers are sound (GH-122233)
## Encode header parts that contain newlines

Per RFC 2047:

> [...] these encoding schemes allow the
> encoding of arbitrary octet values, mail readers that implement this
> decoding should also ensure that display of the decoded data on the
> recipient's terminal will not cause unwanted side-effects

It seems that the "quoted-word" scheme is a valid way to include
a newline character in a header value, just like we already allow
undecodable bytes or control characters.
They do need to be properly quoted when serialized to text, though.


## Verify that email headers are well-formed

This should fail for custom fold() implementations that aren't careful
about newlines.
