[sr-dev] Re: [kamailio/kamailio] extra bytes should be ignored when Content-Length header present (Issue #4290)

In the sanity module documentation, I can see

content length - (128) - checks if the size of the body matches the value from the Content-Length header.

Technically, the SIP message body is equal `Content-Length` header value. Here is the present trailer, which is not specified in the `sanity` module description.

When SDP is smaller or bigger than it is specified in the `Content-Length` header sanity check will properly drop the message because in this case it breaks the RFC. But in this case SIP message is RFC compliant.
