Description

A common attack on sip servers consists of putting SQL injection or JS code into request headers.
Implementing sticky buffers that inspects on headers will permit to detect those attacks.

I propose to start adding keywords for the following fields:

- Via
- From
- To
- User-agent
- Content-type
- Content-length

Why not a generic sip.request_header keyword ? whose buffer would be name+value like http.request_header

Sometimes the inclusion of the header name requires different content logic that is cumbersome. Perhaps sip would be a good target for initial implementation of dynamic sticky buffers as mentioned in #5775?
