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.

- Disable auto credentials by default. This is a breaking change
for clients that are using it, wittingly or not.
- New libcurl ssl option value CURLSSLOPT_AUTO_CLIENT_CERT tells libcurl
to automatically locate and use a client certificate for
authentication, when requested by the server.
- New curl tool options --ssl-auto-client-cert and
--proxy-ssl-auto-client-cert map to CURLSSLOPT_AUTO_CLIENT_CERT.
This option is only supported for Schannel (the native Windows SSL
library). Prior to this change Schannel would, with no notification to
the client, attempt to locate a client certificate and send it to the
server, when requested by the server. Since the server can request any
certificate that supports client authentication in the OS certificate
store it could be a privacy violation and unexpected.

- Save a parallel transfer's result code only when it fails and the

Prior to this change the result code was always set which meant that a
failed result could be erroneously discarded if a different transfer
later had a successful result (CURLE_OK).

Instead output a warning about it and continue with the defaults.
These SSL versions are typically not supported by the TLS libraries since a
long time back already since they are inherently insecure and broken. Asking
for them to be used will just cause an error to be returned slightly later.
In the unlikely event that a user's TLS library actually still supports these
protocol versions, this change might make the request a little less insecure.
Closes#6772
Make sure the total amount of DL/UL bytes are counted before the
transfer finalizes. Otherwise if a transfer finishes too quick, its
total numbers are not added, and results in a DL%/UL% that goes above
100%.
Detail:
progress_meter() is called periodically, and it may not catch a
transfer's total bytes if the value was unknown during the last call,
and the transfer is finished and deleted (i.e., lost) during the next
call.

Fixes#6657Closes#6666
Commit e06fa7462a removed support for libgcrypt leaving only
support for nettle which has been the default crypto library in
GnuTLS for a long time. There were however a few conditionals on
USE_GNUTLS_NETTLE which cause compilation errors in the metalink
code (as it used the gcrypt fallback instead as a result). See the
below autobuild for an example of the error:
https://curl.se/dev/log.cgi?id=20210225123226-30704#prob1
This removes all uses of USE_GNUTLS_NETTLE and also removes the
gcrypt support from the metalink code while at it.

- New libcurl options CURLOPT_DOH_SSL_VERIFYHOST,
CURLOPT_DOH_SSL_VERIFYPEER and CURLOPT_DOH_SSL_VERIFYSTATUS do the
same as their respective counterparts.
- New curl tool options --doh-insecure and --doh-cert-status do the same
as their respective counterparts.
Prior to this change DOH SSL certificate verification settings for
verifyhost and verifypeer were supposed to be inherited respectively
from CURLOPT_SSL_VERIFYHOST and CURLOPT_SSL_VERIFYPEER, but due to a bug
were not. As a result DOH verification remained at the default, ie
enabled, and it was not possible to disable. This commit changes
behavior so that the DOH verification settings are independent and not
inherited.

- Deduplicate the logic used by write-out and write-out json.
Rather than have separate writeLong, writeString, etc, logic for
each of write-out and write-out json instead have respective shared
functions that can output either format and a 'use_json' parameter to
indicate whether it is json that is output.
This will make it easier to maintain. Rather than have to go through
two sets of logic now we only have to go through one.
- Support write-out %{errormsg} and %{exitcode} in json.
- Clarify in the doc that %{exitcode} is the exit code of the transfer.
Prior to this change it just said "The numerical exitcode" which
implies it's the exit code of the tool, and it's not necessarily that.
