Integrate friendly tips from Tor colleagues to make (or not) 4.5 alpha 3;
This includes removal of overloaded (but unused) methods, and addition of
a overlooked call to DataStruct::SetData(nsISupports, uint32_t, bool.)

| michael@0 | 8 | /* |
| michael@0 | 9 | A pushed stream is put into a memory buffer (The SpdyPushTransactionBuffer) |
| michael@0 | 10 | and spooled there until a GET is made that can be matched up with it. At |
| michael@0 | 11 | that time we have two spdy streams - the GET (aka the sink) and the PUSH |
| michael@0 | 12 | (aka the source). Data is copied between those two streams for the lifetime |
| michael@0 | 13 | of the transaction. This is true even if the transaction buffer is empty, |
| michael@0 | 14 | partly complete, or totally loaded at the time the GET correspondence is made. |
| michael@0 | 15 | |
| michael@0 | 16 | correspondence is done through a hash table of the full url, the spdy session, |
| michael@0 | 17 | and the load group. The load group is implicit because that's where the |
| michael@0 | 18 | hash is stored, the other items comprise the hash key. |
| michael@0 | 19 | |
| michael@0 | 20 | Pushed streams are subject to aggressive flow control before they are matched |
| michael@0 | 21 | with a GET at which point flow control is effectively disabled to match the |
| michael@0 | 22 | client pull behavior. |
