Called when the entire stream has been loaded.
This method will always be called asynchronously by the
nsIStreamLoader involved, on the thread that called the
loader’s init() method.
If the observer wants to take over responsibility for the
data buffer (result), it returns NS_SUCCESS_ADOPTED_DATA
in place of NS_OK as its success code. The loader will then
“forget” about the data and not moz_free() it after
onStreamComplete() returns; observer must call moz_free()
when the data is no longer required.
