More correctly handle a selected_len of 0 when processing NPN

In the case where the NPN callback returns with SSL_TLEXT_ERR_OK, but
the selected_len is 0 we should fail. Previously this would fail with an
internal_error alert because calling OPENSSL_malloc(selected_len) will
return NULL when selected_len is 0. We make this error detection more
explicit and return a handshake failure alert.

Partial revert and reimplement "Enable brainpool curves for TLS1.3"

This partially reverts commit 0a10825a0 in order to reimplement it in a
simpler way in the next commit. The reverted aspects are all related to
the TLSv1.3 brainpool curves in the supported_groups extension. Rather
than special casing the handling of these curves we simply add new entries
to the groups table to represent them. They can then be handled without
any additional special casing. This makes the code simpler to maintain.

Stop raising ERR_R_MALLOC_FAILURE in most places

Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.

There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called. Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.

Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

Promote SSL_get_negotiated_group() for non-TLSv1.3

It can be useful to know what group was used for the handshake's
key exchange process even on non-TLS 1.3 connections. Allow this
API, new in OpenSSL 3.0.0, to be used on other TLS versions as well.
Since pre-TLS-1.3 key exchange occurs only on full handshakes, this
necessitates adding a field to the SSL_SESSION object to carry the
group information across resumptions. The key exchange group in the
SSL_SESSION can also be relevant in TLS 1.3 when the resumption handshake
uses the "psk_ke" key-exchange mode, so also track whether a fresh key
exchange was done for TLS 1.3.

Since the new field is optional in the ASN.1 sense, there is no need
to increment SSL_SESSION_ASN1_VERSION (which incurs strong incompatibility
churn).
