1. We mostly operate on transfers and not connections 2. We should avoid "conn->data" Closes #6425

... in most cases instead of 'struct connectdata *' but in some cases in addition to. - We mostly operate on transfers and not connections. - We need the transfer handle to log, store data and more. Everything in libcurl is driven by a transfer (the CURL * in the public API). - This work clarifies and separates the transfers from the connections better. - We should avoid "conn->data". Since individual connections can be used by many transfers when multiplexing, making sure that conn->data points to the current and correct transfer at all times is difficult and has been notoriously error-prone over the years. The goal is to ultimately remove the conn->data pointer for this reason. Closes #6425
