/*
* 4.9 Activation of Bytestream
*
* In order for the bytestream to be used, it MUST first be activated by the StreamHost. If the StreamHost is the Initiator, this is straightforward and does not require any in-band protocol. However, if the StreamHost is a Proxy, the Initiator MUST send an in-band request to the StreamHost. This is done by sending an IQ-set to the Proxy, including an <activate/> element whose XML character data specifies the full JID of the Target.
*
* Example 17. Initiator Requests Activation of Bytestream
*
* <iq type='set'
* from='initiator@host1/foo'
* to='proxy.host3'
* id='activate'>
* <query xmlns='http://jabber.org/protocol/bytestreams' sid='mySID'>
* <activate>target@host2/bar</activate>
* </query>
* </iq>
*
*
* Using this information, with the SID and from address on the packet, the Proxy is able to activate the stream by hashing the SID + Initiator JID + Target JID. This provides a reasonable level of trust that the activation request came from the Initiator.
*
* If the Proxy can fulfill the request, it MUST then respond to the Initiator with an IQ-result.
*
* Example 18. Proxy Informs Initiator of Activation
*
* <iq type='result'
* from='proxy.host3'
* to='initiator@host1/foo'
* id='activate'/>
*
