Correct return values for tls_construct_stoc_next_proto_neg

Return EXT_RETURN_NOT_SENT in the event that we don't send the extension,
rather than EXT_RETURN_SENT. This actually makes no difference at all to
the current control flow since this return value is ignored in this case
anyway. But lets make it correct anyway.

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.
