Fix the issue that aes-xxx-siv algorithms failed in OpenSSL speed test

Speed test, aes-siv related cases fail on both x86 and arm.

Properties: make query cache reference count aware.

The property query cache was not reference count aware and this could cause
problems if the property store removes an algorithm while it is being returned
from an asynchronous query.  This change makes the cache reference count aware
and avoids disappearing algorithms.

A side effect of this change is that the reference counts are now owned by the

Fix Use after free when copying cipher ctx

Fixes #10438
issue found by clusterfuzz/ossfuzz

The dest was getting a copy of the src structure which contained a pointer that should point to an offset inside itself - because of the copy it was pointing to the original structure.

The setup for a ctx is mainly done by the initkey method in the PROV_CIPHER_HW structure. Because of this it makes sense that the structure should also contain a copyctx method that is use to resolve any pointers that need to be setup.

A dup_ctx has been added to the cipher_enc tests in evp_test. It does a dup after setup and then frees the original ctx. This detects any floating pointers in the duplicated context that were pointing back to the freed ctx.

Update source files for pre-3.0 deprecation

Reviewed-by: Tim Hudson <tjh@openssl.org>
(Merged from https://github.com/openssl/openssl/pull/10364)

Update source files for deprecation at 3.0

Previous macros suggested that from 3.0, we're only allowed to
deprecate things at a major version.  However, there's no policy
stating this, but there is for removal, saying that to remove
something, it must have been deprecated for 5 years, and that removal
can only happen at a major version.

Meanwhile, the semantic versioning rule is that deprecation should
trigger a MINOR version update, which is reflected in the macro names
as of this change.

Change the logic and behaviour surrounding '--api' and 'no-deprecated'

At some point in time, there was a 'no-deprecated' configuration
option, which had the effect of hiding all declarations of deprecated
stuff, i.e. make the public API look like they were all removed.

At some point in time, there was a '--api' configuration option, which
had the effect of having the public API look like it did in the version
given as value, on a best effort basis.  In practice, this was used to
get different implementations of BN_zero(), depending on the desired
API compatibility level.

At some later point in time, '--api' was changed to mean the same as
'no-deprecated', but only for the deprecations up to and including the
desired API compatibility level.  BN_zero() has been set to the
pre-1.0.0 implementation ever since, unless 'no-deprecation' has been
given.

This change turns these options back to their original meaning, but
with the slight twist that when combined, i.e. both '--api' and
'no-deprecated' is given, the declarations that are marked deprecated
up to an including the desired API compatibility level are hidden,
simulating that they have been removed.

If no desired API compatibility level has been given, then
configuration sets the current OpenSSL version by default.

Furthermore, the macro OPENSSL_API_LEVEL is now used exclusively to
check what API compatibility level is desired.  For checking in code
if `no-deprecated` has been configured for the desired API
compatibility level, macros for each supported level is generated,
such as OPENSSL_NO_DEPRECATED_1_1_1, corresponding to the use of
DEPRECATEDIN_ macros, such as DEPRECATEDIN_1_1_1().

Just like before, to set an API compatibility level when building an
application, define OPENSSL_API_COMPAT with an appropriate value.  If
it's desirable to hide deprecated functions up to and including that
level, additionally define OPENSSL_NO_DEPRECATED (the value is
ignored).

util/*.num: deassign ordinal numbers from new symbols

Symbols that have appeared since 1.1.1 was released are considered
unassigned in the development branch.   This is marked by having a
question mark as its ordinal number.

This introduces two new markers to be used instead of ordinal numbers:

    ?   signifying it gets the previous symbol's number plus one
    ?+  signifying it gets the same number as the previous symbol

'?+' should remain rare, but is useful to create aliases when needed
(for example when two different symbols clash because they only differ
in character case, see include/openssl/symhacks.h)

The intention is that a development branch won't have set numbers for
new symbols, and that the final numbers will only get allocated when
making beta or final releases.
