RFC 7838 section 5:
When using an alternative service, clients SHOULD include an Alt-Used

Removed CURLALTSVC_ALTUSED again (feature is still EXPERIMENTAL thus

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

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#3653Closes#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.

Repeatedly we see problems where using curl_multi_wait() is difficult or
just awkward because if it has no file descriptor to wait for
internally, it returns immediately and leaves it to the caller to wait
for a small amount of time in order to avoid occasional busy-looping.
This is often missed or misunderstood, leading to underperforming
applications.
This change introduces curl_multi_poll() as a replacement drop-in
function that accepts the exact same set of arguments. This function
works identically to curl_multi_wait() - EXCEPT - for the case when
there's nothing to wait for internally, as then this function will by
itself wait for a "suitable" short time before it returns. This
effectiely avoids all risks of busy-looping and should also make it less
likely that apps "over-wait".
This also changes the curl tool to use this funtion internally when
doing parallel transfers and changes curl_easy_perform() to use it
internally.
Closes#4163

If HTTPAUTH_GSSNEGOTIATE was used for a POST request and

- In curl_easy_reset attempt to resize the receive buffer to its default
size. If realloc fails then continue using the previous size.
Prior to this change curl_easy_reset did not properly handle resetting
the receive buffer (data->state.buffer). It reset the variable holding
its size (data->set.buffer_size) to the default size (READBUFFER_SIZE)
but then did not actually resize the buffer. If a user resized the
buffer by using CURLOPT_BUFFERSIZE to set the size smaller than the
default, later called curl_easy_reset and attempted to reuse the handle
then a heap overflow would very likely occur during that handle's next
transfer.

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.

There were a leftover few prototypes of Curl_ functions that we used to
export but no longer do, this removes those prototypes and cleans up any
comments still referring to them.
Curl_write32_le(), Curl_strcpy_url(), Curl_strlen_url(), Curl_up_free()
Curl_concat_url(), Curl_detach_connnection(), Curl_http_setup_conn()
were made static in 05b100aee2.
Curl_http_perhapsrewind() made static in 574aecee20.
For the remainder, I didn't trawl the Git logs hard enough to capture
their exact time of deletion, but they were all gone: Curl_splayprint(),
Curl_http2_send_request(), Curl_global_host_cache_dtor(),
Curl_scan_cache_used(), Curl_hostcache_destroy(), Curl_second_connect(),
Curl_http_auth_stage() and Curl_close_connections().

The value of the maxPTDs parameter to PR_Init() has since at least
NSPR 2.1, which was released sometime in 1998, been marked ignored
as is accordingly not used in the initialization code. Setting it

intent which may be misleading. Reset the value to zero to improve
clarity.

The header buffer size calculation can from static analysis seem to
overlow as it performs an addition between two size_t variables and
stores the result in a size_t variable. Overflow is however guarded
against elsewhere since the input to the addition is regulated by
the maximum read buffer size. Clarify this with a comment since the
question was asked.
