http: fix crash in rate-limited upload

- 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.

http: fix crash in rate-limited upload

- 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.

openssl: avoid static variable for seed flag

Avoid the race condition risk by instead storing the "seeded" flag in
the multi handle. Modern OpenSSL versions handle the seeding itself so
doing the seeding once per multi-handle instead of once per process is
less of an issue.

multi: alter transfer timeout ordering

- Check whether a connection has succeded before checking whether it's
timed out.

This means if we've connected quickly, but subsequently been
descheduled, we allow the connection to succeed. Note, if we timeout,
but between checking the timeout, and connecting to the server the
connection succeeds, we will allow it to go ahead. This is viewed as
an acceptable trade off.

- Add additional failf logging around failed connection attempts to
propogate the cause up to the caller.
