The API is soon two years old and deserves being shown as the primary
way to drive multi code as it makes it much easier to write code.
multi-poll: removed
multi-legacy: add to show how we did multi API use before
curl_multi_wait/poll.
Closes#7352
The same callback code is used in:
imap-append.c
smtp-authzid.c
smtp-mail.c
smtp-multi.c
smtp-ssl.c
smtp-tls.c
It should not assume that it can copy full lines into the buffer as it
will encourage sloppy coding practices. Instead use byte-wise logic and
check/acknowledge the buffer size appropriately.

Closes#7301
Unicode Windows builds use UTF-8 strings internally in libcurl,
so make sure to call the UTF-8 flavour of the libidn2 API. Also
document that Windows builds with libidn2 and UNICODE do expect
CURLOPT_URL as an UTF-8 string.

They were never officially allowed and slipped in only due to sloppy
parsing. Spaces (ascii 32) should be correctly encoded (to %20) before
being part of a URL.
The new flag bit CURLU_ALLOW_SPACE when a full URL is set, makes libcurl
allow spaces.
Updated test 1560 to verify.

- Document that HTTP/2 multiplexing is supported by the curl tool when
parallel transfers are used.
Supported since 7.66.0 via --parallel, but the doc wasn't updated.

Warning: this will make existing curl command lines that use metalink to
stop working.
Reasons for removal:
1. We've found several security problems and issues involving the
metalink support in curl. The issues are not detailed here. When
working on those, it become apparent to the team that several of the
problems are due to the system design, metalink library API and what
the metalink RFC says. They are very hard to fix on the curl side
only.
2. The metalink usage with curl was only very briefly documented and was
not following the "normal" curl usage pattern in several ways, making
it surprising and non-intuitive which could lead to further security
issues.
3. The metalink library was last updated 6 years ago and wasn't so
active the years before that either. An unmaintained library means
there's a security problem waiting to happen. This is probably reason
enough.
4. Metalink requires an XML parsing library, which is complex code (even
the smaller alternatives) and to this day often gets security
updates.
5. Metalink is not a widely used curl feature. In the 2020 curl user
survey, only 1.4% of the responders said that they'd are using it. In
2021 that number was 1.2%. Searching the web also show very few
traces of it being used, even with other tools.
6. The torrent format and associated technology clearly won for
downloading large files from multiple sources in parallel.

For options that pass in lists or strings that are subsequently parsed
and must be correct. This broadens the scope for the option previously
known as CURLE_TELNET_OPTION_SYNTAX but the old name is of course still
provided as a #define for existing applications.
Closes#7175
In INSTALL.MD, it's currently set to CURL-DISABLE-md instead of
CURL-DISABLE.md. This generates a 404 on the cURL website as well as
when viewing the docs through Github.
Closes#7142
In some situations, it was possible that a transfer was setup to
use an specific IP version, but due do DNS caching or connection
reuse, it ended up using a different IP version from requested.
This commit changes the effect of CURLOPT_IPRESOLVE from simply
restricting address resolution to preventing the wrong connection
type being used, when choosing a connection from the pool, and
to restricting what addresses could be used when establishing
a new connection.
It is important that all addresses versions are resolved, even if
not used in that transfer in particular, because the result is
cached, and could be useful for a different transfer with a
different CURLOPT_IPRESOLVE setting.

This adds the I/O prefix to indicate that those "actions" are kind-of
related to those found in select(2) or poll(2) (reading/writing).
It also adds a note where the prototypes of those functions can be found
in the source code.

It can't run on focal and causes warnings on bionic. Since the focal
failure started rather suddenly a while ago, we can suspect it might be
temporary.
Added "bring back the build" to the TODO document.

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.
Closes#7022
These functions have existed in the API since the dawn of time. It is

using them.

WHATWG URL has dictated the use of Nontransitional Processing (IDNA

Transitional Processing, but Firefox and Safari have both switched.
Also document the fact that winidn functions differently from libidn2
here.
