FIPS module: adapt for the changed error reporting methods

The FIPS module inner provider doesn't need to deal with error reason
strings or error library number, since it uses the outer provider's
error reporting upcalls.  We therefore disable that code in
crypto/provider_core.c when building the FIPS module.

Replumbing: re-implement error reporting for providers

The idea is that providers should only have to report a reason code.
The library code is considered to be libcrypto internal, and are
allocated dynamically and automatically for providers on creation.

We reserve the upper 8 bits of the reason code for internal OpenSSL
use.  This allows our own providers to report errors in form of a
packed number that includes library number, function number and
reason number.

With this, a provider can potentially use any reason number it wants
from 1 to 16777216, although the current error semantics really only
allow 1 to 4095 (because only the lower 12 bits are currently
considered an actual reason code by the ERR subsystem).

A provider can provide a reason string table in form of an array of
ERR_STRING_DATA, with each item containing just the reason code and
the associated string, with the dispatch function numbered
OSSL_FUNC_PROVIDER_GET_REASON_STRINGS matching the type
OSSL_provider_get_reason_strings_fn.
If available, libcrypto will call that function on provider
activation.

Add extra error text in the property parser

With properties being specified in all kinds of places, including hard
coded in providers, it's not always easy to figure out exactly what
string was incorrect when the parser would just say something like
'parse failed' with no more details.

Adding extra data to the error, showing exactly what string is
incorrect, helps a bit.  At the very least, this gives anyone
interested something to grep for.

crypto/modes/build.conf: Fix MODES asm mistakes

The old rule in Configure was that if the asm source had a file name
with 'ghash-' as part of the name, GHASH_ASM should be defined.  Since
none of the aarch64 asm files has such a name, that macro shouldn't

Following the previous 2 commits also move ecpointformats out of session

The previous 2 commits moved supported groups and ciphers out of the
session object to avoid race conditions. We now also move ecpointformats
for consistency. There does not seem to be a race condition with access
to this data since it is only ever set in a non-resumption handshake.
However, there is no reason for it to be in the session.

Fix a race condition in ciphers handling

Similarly to the previous commit we were storing the peer offered list
of ciphers in the session. In practice there is no need for this
information to be avilable from one resumption to the next since this
list is specific to a particular handshake. Since the session object is
supposed to be immutable we should not be updating it once we have decided
to resume. The solution is to remove the session list out of the session
object.

Fix a race condition in supported groups handling

In TLSv1.3 the supported groups can be negotiated each time a handshake
occurs, regardless of whether we are resuming or not. We should not store
the supported groups information in the session because session objects
can be shared between multiple threads and we can end up with race
conditions. For most users this won't be seen because, by default, we
use stateless tickets in TLSv1.3 which don't get shared. However if you
use SSL_OP_NO_TICKET (to get stateful tickets in TLSv1.3) then this can
happen.

The answer is to move the supported the supported group information into
the SSL object instead.
