7c469fa537 sasl: Implement SASL authorisation identity via CURLOPT_SASL_AUTHZID
Added the ability for the calling program to specify the authorisation
identity (authzid), the identity to act as, in addition to the
authentication identity (authcid) and password when using SASL PLAIN
authentication.

Fixes #3653
Closes #3790

NOTE: This commit was cherry-picked and is part of a series of commits
that added the authzid feature for upcoming 7.66.0. The series was
temporarily reverted in db8ec1f so that it would not ship in a 7.65.x
patch release.

- Revert all commits related to the SASL authzid feature since the next
  release will be a patch release, 7.65.1.

However instead the next release will be a patch release, 7.65.1 and
will not contain any new features.

eb84ca3ea8 sasl: Don't send authcid as authzid for the PLAIN mechanism as per RFC 4616

(authzid) from the authentication identity (authcid) when not specified
by the client.

urldata: rename easy_conn to just conn
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).

ntlm_sspi: fix authentication using Credential Manager
If you pass empty user/pass asking curl to use Windows Credential
Storage (as stated in the docs) and it has valid credentials for the
domain, e.g.
curl -v -u : --ntlm example.com
currently authentication fails.
This change fixes it by providing proper SPN string to the SSPI API
calls.

4f45240bc8 lib: include curl_printf.h as one of the last headers
curl_printf.h defines printf to curl_mprintf, etc. This can cause
problems with external headers which may use
__attribute__((format(printf, ...))) markers etc.

To avoid that they cause problems with system includes, we include
curl_printf.h after any system headers. That makes the three last
headers to always be, and we keep them in this order:

 curl_printf.h
 curl_memory.h
 memdebug.h

None of them include system headers, they all do funny #defines.
