…d read in MIME header

mime/multipart.Reader.ReadForm allows specifying the maximum amount
of memory that will be consumed by the form. While this limit is
correctly applied to the parsed form data structure, it was not
being applied to individual header lines in a form.

For example, when presented with a form containing a header line
that never ends, ReadForm will continue to read the line until it
runs out of memory.

Limit the amount of data consumed when reading a header.
