When asked to resume a download, libcurl will convert that to HTTP logic
and if then the entire file is already transferred it will result in a
416 response from the HTTP server. With CURLOPT_FAILONERRROR set in that
scenario, it should *not* lead to an error return.

The duration of a connect and the total transfer are calculated from two
different time-stamps. It can end up with the total timeout triggering
before the connect timeout expires and we should make sure to
acknowledge whichever timeout that is reached first.
This is especially notable when a transfer first sits in PENDING, as
that time is counted in the total time but the connect timeout is based
on the time since the handle changed to the CONNECT state.
The CONNECTTIMEOUT is per connect attempt. The TIMEOUT is for the entire
operation.

Previously, rustls was using an on-stack array for TLS data. However,
crustls has an (unusual) requirement that buffers it deals with are
initialized before writing to them. By using calloc, we can ensure the
buffer is initialized once and then reuse it across calls.
Closes#6742
Align conditions for NTLM features between CMake and configure
builds by differentiating between USE_NTLM and USE_CURL_NTLM_CORE,
just like curl_setup.h does internally to detect support of:
- USE_NTLM: required for NTLM crypto authentication feature
- USE_CURL_NTLM_CORE: required for SMB protocol
Implement USE_WIN32_CRYPTO detection by checking for Crypt functions
in wincrypt.h which are not available in the Windows App environment.
Link advapi32 and crypt32 for Crypto API and Schannel SSL backend.
Fix condition of Schannel SSL backend in CMake build accordingly.

This requires the latest main branch of crustls, which provides
rustls_client_config_builder_dangerous_set_certificate_verifier and
rustls_client_config_builder_set_enable_sni.
This refactors the session setup into its own function, and adds a new
function cr_hostname_is_ip. Because crustls doesn't support verification
of IP addresses, special handling is needed: We disable SNI and set a
placeholder hostname (which never actually gets sent on the wire).
Closes#6719
Curl_cookie_init can be called with data being NULL, and this can in turn
be passed to Curl_cookie_add, meaning that both functions must be careful
to only use data where it's checked for being a NULL pointer. The libpsl
support code does however dereference data without checking, so if we are
indeed having an unset data pointer we cannot PSL check the cookiedomain.
This is currently not a reachable dereference, as the only caller with a
NULL data isn't passing a file to initialize cookies from, but since the
API has this contract let's ensure we hold it.

- Change use of those options from CURLOPT_SSL_OPTIONS that are not
already evaluated via SSL_SET_OPTION in schannel and secure transport
to use that instead of data->set.ssl.optname.
Example:
Evaluate SSL_SET_OPTION(no_revoke) instead of data->set.ssl.no_revoke.
This change is because options set via CURLOPT_SSL_OPTIONS
(data->set.ssl.optname) are separate from those set for HTTPS proxy via
CURLOPT_PROXY_SSL_OPTIONS (data->set.proxy_ssl.optname). The
SSL_SET_OPTION macro determines whether the connection is for HTTPS
proxy and based on that which option to evaluate.
Since neither Schannel nor Secure Transport backends currently support
HTTPS proxy in libcurl, this change is for posterity and has no other
effect.

unescaped is coming from Curl_urldecode and not a unicode conversion
function, so reclaiming its memory should be performed with a normal
call to free rather than curlx_unicodefree. In reality, this is the
same thing as curlx_unicodefree is implemented as a call to free but
that's not guaranteed to always hold. Using the curlx macro present
issues with memory debugging as well.

Commit e06fa7462a removed support for libgcrypt leaving only
support for nettle which has been the default crypto library in
GnuTLS for a long time. There were however a few conditionals on
USE_GNUTLS_NETTLE which cause compilation errors in the metalink
code (as it used the gcrypt fallback instead as a result). See the
below autobuild for an example of the error:
https://curl.se/dev/log.cgi?id=20210225123226-30704#prob1
This removes all uses of USE_GNUTLS_NETTLE and also removes the
gcrypt support from the metalink code while at it.
