Also added 'CURL_SMALLSENDS' to make Curl_write() send short packets,
which helped verifying this even more.
Add test 363 to verify.

... 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
- During the end-of-headers response phase do not mark the tunnel
complete unless the response body was completely parsed/ignored.
Prior to this change if the entirety of a CONNECT response with chunked
encoding was not received by the time the final header was parsed then
the connection would be marked done prematurely, before all the chunked
data could be read in and ignored (since this is what we do with any
CONNECT response body) and the connection could not be used.

Closes https://github.com/curl/curl/pull/6432
When doing a request with a request body expecting a 401/407 back, that
initial request is sent with a zero content-length. Test 177 and more.

... as that counter is subsequently used to detect if nothing was
returned from the peer. This made curl return CURLE_OK when it should
have returned CURLE_GOT_NOTHING.

Closes#5994
Since the connection can be used by many independent requests (using
HTTP/2 or HTTP/3), things like user-agent and other transfer-specific
data MUST NOT be kept connection oriented as it could lead to requests
getting the wrong string for their requests. This struct data was
lingering like this due to old HTTP1 legacy thinking where it didn't
mattered..
Fixes#5566Closes#5567
A common set of functions instead of many separate implementations for
creating buffers that can grow when appending data to them. Existing
functionality has been ported over.
In my early basic testing, the total number of allocations seem at
roughly the same amount as before, possibly a few less.
See docs/DYNBUF.md for a description of the API.
Closes#5300
We use "conn" everywhere to be a pointer to the connection.
Introduces two functions that "attaches" and "detaches" the connection
to and from the transfer.
Going forward, we should favour using "data->conn" (since a transfer
always only has a single connection or none at all) to "conn->data"
(since a connection can have none, one or many transfers associated with
it and updating conn->data to be correct is error prone and a frequent
reason for internal issues).
Closes#3442
- Get rid of variable that was generating false positive warning
(unitialized)
- Fix issues in tests
- Reduce scope of several variables all over
etc
Closes#2631
`conn->connect_state` is NULL when doing a regular non-CONNECT request
over the proxy and should therefor be considered complete at once.

... the previous code would reset the header length wrongly (since
5113ad0424). This makes test 1060 reliable again.
Also: make sws send even smaller chunks of data to increase the
likeliness of this happening.
- Add new option CURLOPT_SUPPRESS_CONNECT_HEADERS to allow suppressing
proxy CONNECT response headers from the user callback functions
CURLOPT_HEADERFUNCTION and CURLOPT_WRITEFUNCTION.
- Add new tool option --suppress-connect-headers to expose
CURLOPT_SUPPRESS_CONNECT_HEADERS and allow suppressing proxy CONNECT
response headers from --dump-header and --include.
