Computing the binders on ClientHelloInner is a little interesting. While
I'm in the area, tidy this up a bit. The exploded parameters may as well
be an SSL_SESSION, and hash_transcript_and_truncated_client_hello can
just get folded in.

We misread (or maybe it changed?) the draft padding scheme. The current
text does not round the whole payload to a multiple of 32, just the
server name as a fallback. Switch the GREASE size selection to match.
Although, we may want to change the draft here. See also
https://github.com/tlswg/draft-ietf-tls-esni/issues/433
While I'm here, update some references from draft-09 to draft-10. Also
make the comment less verbose.

It's not even accurate. The term "master key" dates to SSL 2, which we
do not implement. (Starting SSL 3, "key" was replaced with "secret".)
The field stores, at various points, the TLS 1.2 master secret, the TLS
1.3 resumption master secret, and the TLS 1.3 resumption PSK. Simply
rename the field to 'secret', which is as descriptive of a name as we
can get at this point.
I've left SSL_SESSION_get_master_key alone for now, as it's there for
OpenSSL compatibility, as well as references to the various TLS secrets
since those refer to concepts in the spec. (When the dust settles a bit
on rfc8446bis, we can fix those.)
