Add parser for CURLOPT_SSL_CIPHER_LIST option for Secure Transport (ST)
back-end. Similar to NSS and GSKit back-ends, new code parses string
value and configures ST library to use those ciphers for communication.
Create cipher spec data structure and initialize the array of specs with
cipher number, name, alias, and 'weak' flag.
Mark triple-DES ciphers as 'weak', and exclude them from the default
ciphers list.

... previously they were supported if a TLS library would (unexpectedly)
still support them, but from this change they will be refused already in
curl_easy_setopt(). SSLv2 and SSLv3 have been known to be insecure for
many years now.

- 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.

Rename it to 'httpwant' and make a cloned field in the state struct as
well for run-time updates.
Also: refuse non-supported HTTP versions. Verified with test 129.
Closes#6585
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.
- We mostly operate on transfers and not connections.
- We need the transfer handle to log, store data and more. Everything in
libcurl is driven by a transfer (the CURL * in the public API).
- This work clarifies and separates the transfers from the connections
better.
- We should avoid "conn->data". Since individual connections can be used
by many transfers when multiplexing, making sure that conn->data
points to the current and correct transfer at all times is difficult
and has been notoriously error-prone over the years. The goal is to
ultimately remove the conn->data pointer for this reason.
Closes#6425
This change introduces a generic way to provide binary data in setopt
options, called BLOBs.
This change introduces these new setopts:
CURLOPT_ISSUERCERT_BLOB, CURLOPT_PROXY_SSLCERT_BLOB,
CURLOPT_PROXY_SSLKEY_BLOB, CURLOPT_SSLCERT_BLOB and CURLOPT_SSLKEY_BLOB.

They serve very little purpose and mostly just add noise. Most of them
have been around for a very long time. I read them all before removing
or rephrasing them.
Ref: #3876Closes#3883
As soon as a TLS backend gets ALPN conformation about the specific HTTP
version it can now set the multiplex situation for the "bundle" and
trigger moving potentially queued up transfers to the CONNECT state.
