OpenSSL.
Closes#4304
SSL_VersionRangeGetDefault returns (TLSv1.0, TLSv1.2) as supported
range in NSS 3.45. It looks like the intention is to raise the minimum
version rather than lowering the maximum, so adjust accordingly. Note
that the caller (nss_setup_connect) initializes the version range to
(TLSv1.0, TLSv1.3), so there is no need to check for >= TLSv1.0 again.

Older versions of OpenSSL report FIPS availabilty via an OPENSSL_FIPS
define. It uses this define to determine whether to publish -fips at
the end of the version displayed. Applications that utilize the version
reported by OpenSSL will see a mismatch if they compare it to what curl
reports, as curl is not modifying the version in the same way. This
change simply adds a check to see if OPENSSL_FIPS is defined, and will
alter the reported version to match what OpenSSL itself provides. This
only appears to be applicable in versions of OpenSSL <1.1.1
Closes#3771
Currently you can do things like --cert <(cat ./cert.crt) with (at least) the
openssl backend, but that doesn't work for nss because is_file rejects fifos.
I don't actually know if this is sufficient, nss might do things internally
(like seeking back) that make this not work, so actual testing is needed.

As soon as a TLS backend gets ALPN conformation about the specific HTTP

NSS may be built without support for the latest SSL/TLS versions,

code supports a recent version (e.g. TLS v1.3) but it has explicitly

be the maximum supported version at runtime, as long as that version
is at least as high as the minimum version required by libcurl.

Session resumption information is not available immediately after a TLS 1.3
handshake. The client must wait until the server has sent a session ticket.
Use OpenSSL's "new session" callback to get the session information and put it
into curl's session cache. For TLS 1.3 sessions, this callback will be invoked
after the server has sent a session ticket.
The "new session" callback is invoked only if OpenSSL's session cache is
enabled, so enable it and use the "external storage" mode which lets curl manage
the contents of the session cache.
A pointer to the connection data and the sockindex are now saved as "SSL extra
data" to make them available to the callback.
This approach also works for old SSL/TLS versions and old OpenSSL versions.

adds checking and error handling to a few cases where the allocation
wasn't checked for success. In the ftp case, the freeing of the path
variable is moved ahead of the allocation since there is little point
in keeping it around across the strdup, and the separation makes for
more readable code. In nwlib, the lock is aslo freed in the error path.
