Subject: [PATCH 04/11] Fix GHSA-9pqp-7h25-4f32
multipart/form-data boundaries larger than the read buffer result in erroneous
parsing, which violates data integrity.
Limit boundary size, as allowed by RFC 1521:
Encapsulation boundaries [...] must be no longer than 70 characters, not
counting the two leading hyphens.
We correctly parse payloads with boundaries of length up to
FILLUNIT-strlen("\r\n--") bytes, so allow this for BC.
