cleanup: remove DOT_CHAR completely
Follow-up to f9c7ba9096

The use of DOT_CHAR for ".ssh" was probably a mistake and is removed
now.

alt-svc: add protocol version selection masking
So that users can mask in/out specific HTTP versions when Alt-Svc is
used.

 - Removed "h2c" and updated test case accordingly
 - Changed how the altsvc struct is laid out
 - Added ifdefs to make the unittest run even in a quiche-tree

alt-svc: send Alt-Used: in redirected requests
RFC 7838 section 5:

   When using an alternative service, clients SHOULD include an Alt-Used
   header field in all requests.

Removed CURLALTSVC_ALTUSED again (feature is still EXPERIMENTAL thus
this is deemed ok).

You can disable sending this header just like you disable any other HTTP
header in libcurl.

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.

e8442e4ffc libcurl: Restrict redirect schemes (follow-up)

libcurl: Restrict redirect schemes
All protocols except for CURLPROTO_FILE/CURLPROTO_SMB and their TLS
counterpart were allowed for redirect. This vastly broadens the
exploitation surface in case of a vulnerability such as SSRF [1], where
libcurl-based clients are forced to make requests to arbitrary hosts.

For instance, CURLPROTO_GOPHER can be used to smuggle any TCP-based
protocol by URL-encoding a payload in the URI. Gopher will open a TCP
connection and send the payload.

Only HTTP/HTTPS and FTP are allowed. All other protocols have to be
explicitly enabled for redirects through CURLOPT_REDIR_PROTOCOLS.

f67009dd98 url: Fix CURLOPT_MAXAGE_CONN time comparison
Old connections are meant to expire from the connection cache after
CURLOPT_MAXAGE_CONN seconds. However, they actually expire after 1000x
that value. This occurs because a time value measured in milliseconds is
accidentally divided by 1M instead of by 1,000.

multi: make sure 'data' can present in several sockhash entries
Since more than one socket can be used by each transfer at a given time,
each sockhash entry how has its own hash table with transfers using that
socket.

In addition, the sockhash entry can now be marked 'blocked = TRUE'"
which then makes the delete function just set 'removed = TRUE' instead
of removing it "for real", as a way to not rip out the carpet under the
feet of a parent function that iterates over the transfers of that same
sockhash entry.

will not contain any new features.

- Split off connection shutdown procedure from Curl_disconnect into new
  function conn_shutdown.

- Change the shutdown procedure to close the sockets before
  disassociating the transfer.

Prior to this change the sockets were closed after disassociating the
transfer so SOCKETFUNCTION wasn't called since the transfer was already
disassociated. That likely came about from recent work started in
Jan 2019 (#3442) to separate transfers from connections.
