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.
Closes#7073
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.
Cloes #7176
This reverts commit 1cba36d216.
CMake provides properties that can be set on a target to rename the
output artifact without changing the name of a target.
Ref: #6899
When the host name in a URL is given as an IPv4 numerical address, the
address can be specified with dotted numericals in four different ways:
a32, a.b24, a.b.c16 or a.b.c.d and each part can be specified in
decimal, octal (0-prefixed) or hexadecimal (0x-prefixed).
Instead of passing on the name as-is and leaving the handling to the
underlying name functions, which made them not work with c-ares but work
with getaddrinfo, this change now makes the curl URL API itself detect
and "normalize" host names specified as IPv4 numericals.
The WHATWG URL Spec says this is an okay way to specify a host name in a
URL. RFC 3896 does not allow them, but curl didn't prevent them before
and it seems other RFC 3896-using tools have not either. Host names used
like this are widely supported by other tools as well due to the
handling being done by getaddrinfo and friends.
I decided to add the functionality into the URL API itself so that all
users of these functions get the benefits, when for example wanting to
compare two URLs. Also, it makes curl built to use c-ares now support
them as well and make curl builds more consistent.
The normalization makes HTTPS and virtual hosted HTTP work fine even
when curl gets the address specified using one of the "obscure" formats.
Test 1560 is extended to verify.

When asked to resume a download, libcurl will convert that to HTTP logic
and if then the entire file is already transferred it will result in a
416 response from the HTTP server. With CURLOPT_FAILONERRROR set in that
scenario, it should *not* lead to an error return.

handle reuse which should use the setting as the user specified it.
Added test 1569 to verify: it first makes an FTP transfer with ';type=A'
and then another without type on the same handle and the second should
then use binary. Previously, curl failed this.

it's worth dropping the british name.
