Don't modify resumed session objects

If s->hit is set, s->session corresponds to a session created on
a previous connection, and is a data structure that is potentially
shared across other SSL objects.  As such, there are thread-safety
issues with modifying the structure without taking its lock (and
of course all corresponding read accesses would also need to take
the lock as well), which have been observed to cause double-frees.

Regardless of thread-safety, the resumed session object is intended
to reflect parameters of the connection that created the session,
and modifying it to reflect the parameters from the current connection
is confusing.  So, modifications to the session object during
ClientHello processing should only be performed on new connections,
i.e., those where s->hit is not set.

The code mostly got this right, providing such checks when processing
SNI and EC point formats, but the supported groups (formerly
supported curves) extension was missing it, which is fixed by this commit.

However, TLS 1.3 makes the suppported_groups extension mandatory
(when using (EC)DHE, which is the normal case), checking for the group
list in the key_share extension processing.  But, TLS 1.3 only [0] supports
session tickets for session resumption, so the session object in question
is the output of d2i_SSL_SESSION(), and will not be shared across SSL
objects.  Thus, it is safe to modify s->session for TLS 1.3 connections.

[0] A psk_find_session callback can also be used, but the restriction that
each callback execution must produce a distinct SSL_SESSION structure
can be documented when the psk_find_session callback documentation is
completed.

Fix memory leak in session cache test

When we are using the internal cache we have to make a copy of the
session before removing it from the parent context's cache, since
we want our copy to still be resumable.  However, SSL_CTX_remove_session()
just detaches the session from the SSL_CTX; it does not free the session.
So, we must call SSL_SESSION_free() ourselves before overwriting the
variable that we dup'd from.

Remove the obsolete misleading comment and code related to it.

The comment "The following should not return 1, otherwise, things
are very strange" is from the very first commit of OpenSSL. The
really meaning of the comment is if the identical session can be
found from internal cache after calling get_session_cb but not
found before calling get_session_cb, it is just strange.

The value 1 was originated from the old doc of SSLeay, reversed
from the actual return value of SSL_CTX_add_session().

Anyway either return value of SSL_CTX_add_session() should not
interrupt the session resumption process. So the checking of
return value of SSL_CTX_add_session() is not necessary.

Fix typo in documents

I scanned all files in the doc folder with a spell checker (https://github.com/EWSoftware/VSSpellChecker).
This patch (hopefully) corrected all spell errors that it found.

Fix SSL_set_tlsext_debug_callback/-tlsextdebug

Some extensions were being displayed twice, before they were parsed, and
again after they were parsed.
The supported_versions extension was not being fully displayed, as it
was processed differently than other extensions.

Move the debug callback to where the extensions are first collected, to
catch all the extensions as they come in, so they are ordered correctly.

Fix the names of older ciphers.

The names of these ciphers have an "SSL_" prefix, but the RFC names use
"TLS_":
https://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml#tls-parameters-4

This dates back to these ciphers being originally defined in SSLv3. As
SSLv3 is on its way out anyway and this is a new set of APIs,
consistently use the TLS names.

I think it's better to use `GetFileAttributes` to obtain the attributes

Perl: Use File::Glob::bsd_glob rather than File::Glob::glob

message:

    File::Glob::glob() will disappear in perl 5.30. Use File::Glob::bsd_glob() instead. at ../master/Configure line 277.

So instead, use a construction that makes the caller glob() use
File::Glob::bsd_glob().

Note that we're still excluding VMS, as it's directory specs use '['
