email: Tolerate non-ASCII non-UTF-8 characters in headers.
* email/email.scm (email->headers+body): If non-ASCII non-UTF-8
characters occur in the headers, do not raise a decoding error. Work
around using the substitute conversion strategy.
* tests/email.scm ("tolerate non-ASCII characters in headers"): Rename
to "decode utf-8 characters in headers".
("tolerate non-ascii non-utf-8 characters in headers"): New test.
