url: normalize CURLINFO_EFFECTIVE_URL
The URL extracted with CURLINFO_EFFECTIVE_URL was returned as given as
input in most cases, which made it not get a scheme prefixed like before
if the URL was given without one, and it didn't remove dotdot sequences
etc.

Added test case 1907 to verify that this now works as intended and as
before 7.62.0.

Regression introduced in 7.62.0

http2: move state-init from creation to pre-transfer
To make sure that the HTTP/2 state is initialized correctly for
duplicated handles. It would otherwise easily generate "spurious"

Jay Satiro cded993700 url: don't set appconnect time for non-ssl/non-ssh connections
Prior to this change non-ssl/non-ssh connections that were reused set
TIMER_APPCONNECT [1]. Arguably that was incorrect since no SSL/SSH
handshake took place.

[1]: TIMER_APPCONNECT is publicly known as CURLINFO_APPCONNECT_TIME in
libcurl and %{time_appconnect} in the curl tool. It is documented as
"the time until the SSL/SSH handshake is completed".

If you set the same URL for target as for DoH (and it isn't a DoH

Steve Holme 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.

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.

Old connections are meant to expire from the connection cache after
CURLOPT_MAXAGE_CONN seconds. However, they actually expire after 1000x

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.
