filter: avoid integer overflow in authenticate_post
ctx.env.content_length is an unsigned int, coming from the
CONTENT_LENGTH environment variable, which is parsed by strtoul. The
HTTP/1.1 spec says that "any Content-Length greater than or equal to
zero is a valid value." By storing this into an int, we potentially
overflow it, resulting in the following bounding check failing, leading
to a buffer overflow.
