When parsing incoming headers, they need to have a plain normal colon.
Previously out of convenience we used the same parser function for both
cases (incoming + custom set headers via the API) which made the
function too liberal for incoming HTTP traffic.

After this patch, the codebase no longer overrides system printf
functions. Instead it explicitly calls either the curl printf functions
`curl_m*printf()` or the system ones using their original names.
Also:
- drop unused `curl_printf.h` includes.
- checksrc: ban system printf functions, allow where necessary.

Improvements around HTTP Upgrade: and multiplex hanndling:
* add `Curl_conn_set_multiplex()` to set connection's multiplex
bit and trigger "connchanged" events
* call `Curl_conn_set_multiplex()` in filters' `CF_CTRL_CONN_INFO_UPDATE`
implementation where other connection properties are updated.
This prevents connection updates before the final filter chain
is chosen.
* rename enum `UPGR101_INIT` to `UPGR101_NONE`
* rename connection bit `asks_multiplex` to `upgrade_in_progress`
* trigger "connchanged" when `upgrade_in_progress` clears
* rename `WebSockets` to `WebSocket` as it is the common term
used in documentation
Closes#18227
A previous refactor of cookie logic changed Curl_cookie_getlist to no
longer return a list of copied cookies, but instead return a linked list
pointing to existing cookies. The returned linked list is accessed
outside of the scope of the cookie share lock in http_cookies, which
leads to issues if the shared cookie list is modified at the same time.
This is the relevant commit: be39ed1Closes#18457
By returning error separately on parse errors and avoiding magic
numbers, this function can now return 0 or -1 as proper dates when such
a date string is provided.

Split out adding of individual request headers into a switch. Check

Add TE: header directly without allocation. Add bit for indicating

- add Curl_secure_context(), to have it determined in a single place.

Write out 9-length frames to client's WRITEFUNCTION
Read 0-length frames from READFUNCTION *if* the function
started a new frame via `curl_ws_start_frame()`.

Add support for CURLOPT_READFUNCTION with WebSocket urls when *not* in
connect-only mode, e.g. when using curl_multi_perform.
Install the callback function and set CURLOPT_UPLOAD. Return
CURL_READFUNC_PAUSE when having nothing more to send and unpause the
transfer when more data is ready.
This will send the read bytes in a WebSocket BINARY frame.
Add support for this mode in the pytest "ws_data" client and have all
tests run in 'curl_ws_send/recv' and 'peform' mode as well.
Add `curl_ws_start_frame()`. Document, cover in libcurl-ws.md and
explain the READFUNCTION mode for websockets.
Add example `websocket-updown` for this.
Closes#17683
Deduce that the transfer response expects headers by the protocol
handler implementing `write_resp_hd` callback. This eleminates the
`getheader` parameter in the `Curl_xfer_setup_*()` methods.
Add an implementation to RTSP for `write_resp_hd`, joining the HTTP
protocol in the only handlers having it.
Reverse the default of request's `header` bit that signals that headers
are expected. Default is now FALSE, set to TRUE when setting up the
transfer by presence of `write_resp_hd` in the protocol handler.
Closes#18218
Make variants for transfers that send/receive or do both with just the
parameters they need. Split out the shutdown setting into a separate
function. Only FTP bothers with that.
Closes#18203
The `connectdata` members `sockfd` and `writesockfd` needed to by either
CURL_SOCKET_BAD or a copy of one of `conn->sock[2]`. When equal to one,
that index was used to send/recv/poll the proper socket or connection
filter chain.
Replace those with `send_idx` and `recv_idx` which are either -1, 0 or 1
to indicate which socket/filter to send/receive on.
Closes#18179
When a HTTP version has been negotiated via ALPN, set the member
`conn->httpversion_seen` accordingly. This allows pending transfers to
reuse multiplexed http connections before the response to the first
transfer has arrived.

`getsock()` calls operated on a global limit that could
not be configure beyond 16 sockets. This is no longer adequate
with the new happy eyeballing strategy.
Instead, do the following:
- make `struct easy_pollset` dynamic. Starting with
a minimal room for two sockets, the very common case,
allow it to grow on demand.
- replace all protocol handler getsock() calls with pollsets
and a CURLcode to return failures
- add CURLcode return for all connection filter `adjust_pollset()`
callbacks, since they too can now fail.
- use appropriately in multi.c and multi_ev.c
- fix unit2600 to trigger pollset growth
Closes#18164
Since the content varies during connection setup and while doing it
(eyeballing), remove these strcut from `connectdata` and replace use
with querying the connection filters. Those keep that information
already.
Change the info logging of established connections to also give the
local address and port.
Closes#17960
Add a connection filter query to obtained the negotiated ALPN
protocol to check in setup/protocols how the connection needs
to behave.
Remove the members `alpn` and `proxy_alpn` from `connectdata`.

This became an issue after promoting curl compiler warnings to errors in
curl-for-win. The code is correct. It over-allocates a struct to store
variable sized data past its length. Similar code is present in
`lib/smb.c`, silenced earlier.

Closes#17962
The `transport` to use for a transfer, e.g. TCP/QUIC/UNIX/UDP, is
initially selected by options and protocol used. This is set at the
`struct connectdata` as `transport` member.
During connection establishment, this transport may change due to
Alt-Svc or Happy-Eyeballing. Most common is the switch from TCP to QUIC.
Rename the connection member to `transport_wanted` and add a way to
query the connection for the transport in use via a new connection
filter query.
The filter query can also be used in the happy eyeballing attempts when
code needs to know which transport is used by the "filter below". This
happens in wolfssl initialization, as one example.

When inspecting a possible follow HTTP request, the result of a rewind
of the upload data was ignored as it was not clear at that point in time
if the request would become a GET.
This initiated the followup, rewound again, which failed again and
terminated the follow up.
This was confusing to users as it was not clear of the follow up was
done or not.
Fix: fail the early rewind when the request is not converted to GET.

Move curlx_ functions into its own subdir.
The idea is to use the curlx_ prefix proper on these functions, and use
these same function names both in tool, lib and test suite source code.
Stop the previous special #define setup for curlx_ names.
The printf defines are now done for the library alone. Tests no longer
use the printf defines. The tool code sets its own defines. The printf
functions are not curlx, they are publicly available.
The strcase defines are not curlx_ functions and should not be used by
tool or server code.
dynbuf, warnless, base64, strparse, timeval, timediff are now proper
curlx functions.
When libcurl is built statically, the functions from the library can be
used as-is. The key is then that the functions must work as-is, without
having to be recompiled for use in tool/tests. This avoids symbol
collisions - when libcurl is built statically, we use those functions
directly when building the tool/tests. When libcurl is shared, we
build/link them separately for the tool/tests.
