- Don't set the size of the piece of data to send to the rate limit if
that limit is larger than the buffer size that will hold the piece.
Prior to this change if CURLOPT_MAX_SEND_SPEED_LARGE
(curl tool: --limit-rate) was set then it was possible that a temporary
buffer used for uploading could be written to out of bounds. A likely
scenario for this would be a non-trivial amount of post data combined
with a rate limit larger than CURLOPT_UPLOAD_BUFFERSIZE (default 64k).
The bug was introduced in 24e469f which is in releases since 7.76.0.

Assumed to be a minor coding style improvement with no behavior change.
A modern compiler is expected to have the calculation optimized during
compilation. It may be deemed okay even if that's not the case, since
the added overhead is considered very low.
Closes#7032
Previously this logic would cap the send to CURL_MAX_WRITE_SIZE bytes,
but for the situations where a larger upload buffer has been set, this
function can benefit from sending more bytes. With default size used,
this does the same as before.
Also changed the storage of the size to an 'unsigned int' as it is not
allowed to be set larger than 2M.
Also added cautions to the man pages about changing buffer sizes in
run-time.

... but instead use a private alternative that points to the "driving
transfer" from the connection. We set the "user data" associated with
the connection to be the connectdata struct, but when we drive transfers
the code still needs to know the pointer to the transfer. We can change
the user data to become the Curl_easy handle, but with older nghttp2
version we cannot dynamically update that pointer properly when
different transfers are used over the same connection.
Closes#6520
HTTP auth "accidentally" worked before this cleanup since the code would
always overwrite the connection credentials with the credentials from
the most recent transfer and since HTTP auth is typically done first
thing, this has not been an issue. It was still wrong and subject to
possible race conditions or future breakage if the sequence of functions
would change.
The data.set.str[] strings MUST remain unmodified exactly as set by the
user, and the credentials to use internally are instead set/updated in
state.aptr.*
Added test 675 to verify different credentials used in two requests done
over a reused HTTP connection, which previously behaved wrongly.

... 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.
