res_pjsip: Implement additional SIP RFCs for Google Voice trunk compatability

This change implements a few different generic things which were brought on
by Google Voice SIP.

1. The concept of flow transports have been introduced. These are configurable
transports in pjsip.conf which can be used to reference a flow of signaling
to a target. These have runtime configuration that can be changed by the
signaling itself (such as Service-Routes and P-Preferred-Identity). When used
these guarantee an individual connection (in the case of TCP or TLS) even
if multiple flow transports exist to the same target.

2. Service-Routes (RFC 3608) support has been added to the outbound
registration module which when received will be stored on the flow
transport and used for requests referencing it.

3. P-Associated-URI / P-Preferred-Identity (RFC 3325) support has been
added to the outbound registration module. If a P-Associated-URI header
is received it will be used on requests as the P-Preferred-Identity.

4. Configurable outbound extension support has been added to the outbound
registration module. When set the extension will be placed in the Supported
header.

5. Header parameters can now be configured on an outbound registration
which will be placed in the Contact header.

6. Google specific OAuth / Bearer token authentication
(draft-ietf-sipcore-sip-authn-02) has been added to the outbound registration
module.

All functionality changes are controlled by pjsip.conf configuration options
and do not affect non-configured pjsip endpoints otherwise.
