- Implement new option CURLSSLOPT_REVOKE_BEST_EFFORT and
--ssl-revoke-best-effort to allow a "best effort" revocation check.
A best effort revocation check ignores errors that the revocation check
was unable to take place. The reasoning is described in detail below and
discussed further in the PR.
---
When running e.g. with Fiddler, the schannel backend fails with an
unhelpful error message:
Unknown error (0x80092012) - The revocation function was unable
to check revocation for the certificate.
Sadly, many enterprise users who are stuck behind MITM proxies suffer
the very same problem.
This has been discussed in plenty of issues:
https://github.com/curl/curl/issues/3727,
https://github.com/curl/curl/issues/264, for example.
In the latter, a Microsoft Edge developer even made the case that the
common behavior is to ignore issues when a certificate has no recorded
distribution point for revocation lists, or when the server is offline.
This is also known as "best effort" strategy and addresses the Fiddler
issue.
Unfortunately, this strategy was not chosen as the default for schannel
(and is therefore a backend-specific behavior: OpenSSL seems to happily
ignore the offline servers and missing distribution points).
To maintain backward-compatibility, we therefore add a new flag
(`CURLSSLOPT_REVOKE_BEST_EFFORT`) and a new option
(`--ssl-revoke-best-effort`) to select the new behavior.
Due to the many related issues Git for Windows and GitHub Desktop, the
plan is to make this behavior the default in these software packages.
The test 2070 was added to verify this behavior, adapted from 310.

Add support for CURLSSLOPT_NO_PARTIALCHAIN in CURLOPT_PROXY_SSL_OPTIONS
and OS400 package spec.
Also I added the option to the NameValue list in the tool even though it
isn't exposed as a command-line option (...yet?). (NameValue stringizes
the option name for the curl cmd -> libcurl source generator)
Follow-up to 564d88a which added CURLSSLOPT_NO_PARTIALCHAIN.

- Stop treating lack of HTTP2 as an unknown option error result for
CURLOPT_SSL_ENABLE_ALPN and CURLOPT_SSL_ENABLE_NPN.
Prior to this change it was impossible to disable ALPN / NPN if libcurl
was built without HTTP2. Setting either option would result in
CURLE_UNKNOWN_OPTION and the respective internal option would not be
set. That was incorrect since ALPN and NPN are used independent of
HTTP2.

Even though it cannot fall-back to a lower HTTP version automatically. The

NOTE: This commit was cherry-picked and is part of a series of commits

- Revert all commits related to the SASL authzid feature since the next
release will be a patch release, 7.65.1.
Prior to this change CURLOPT_SASL_AUTHZID / --sasl-authzid was destined
for the next release, assuming it would be a feature release 7.66.0.
However instead the next release will be a patch release, 7.65.1 and
will not contain any new features.
After the patch release after the reverted commits can be restored by
using cherry-pick:

This limits all accepted input strings passed to libcurl to be less than
CURL_MAX_INPUT_LENGTH (8000000) bytes, for these API calls:
curl_easy_setopt() and curl_url_set().
The 8000000 number is arbitrary picked and is meant to detect mistakes
or abuse, not to limit actual practical use cases. By limiting the
acceptable string lengths we also reduce the risk of integer overflows
all over.
NOTE: This does not apply to `CURLOPT_POSTFIELDS`.
Test 1559 verifies.

Commit 9081014 fixed most of the confusing issues between scope id and
scope however 844896d added bad limits checking assuming that the scope
is being set and not the scope id.
I have fixed the documentation so it all refers to scope ids.
In addition Curl_if2ip refered to the scope id as remote_scope_id which
is incorrect, so I renamed it to local_scope_id.

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
Added CURLOPT_HTTP09_ALLOWED and --http0.9 for this purpose.
For now, both the tool and library allow HTTP/0.9 by default.

that applications/scripts can start using them already now.

This adds the CURLOPT_TRAILERDATA and CURLOPT_TRAILERFUNCTION
options that allow a callback based approach to sending trailing headers

Test 1591 checks that trailing headers can be sent using libcurl.
