SIP core library providing abstractions for transports and SIP transactions.

It is the centerpiece of any stateful SIP applications as it provides the `Endpoint`
which holds all low level information about the SIP Stack (transport/transaction state).

While not complete, transport and transaction management are implemented after the following RFCs:

- [RFC3261](https://www.rfc-editor.org/rfc/rfc3261.html) - SIP: Session Initiation Protocol
- [RFC6026](https://www.rfc-editor.org/rfc/rfc6026.html) - Correct Transaction Handling for 2xx Responses to SIP INVITE Requests
