The following built-in curves do not have an assigned OID:
- Oakley-EC2N-3
- Oakley-EC2N-4
In general we shouldn't assume that an OID is always available.
This commit detects such cases, raises an error and returns appropriate
return values so that the condition can be detected and correctly
handled by the callers, when serializing EC parameters or EC keys with
the default `ec_param_enc:named_curve`.

The new naming scheme consistently usese the `OSSL_FUNC_` prefix for all
functions which are dispatched between the core and providers.
This change includes in particular all up- and downcalls, i.e., the
dispatched functions passed from core to provider and vice versa.
- OSSL_core_ -> OSSL_FUNC_core_
- OSSL_provider_ -> OSSL_FUNC_core_
For operations and their function dispatch tables, the following convention
is used:
Type | Name (evp_generic_fetch(3)) |
---------------------|-----------------------------------|
operation | OSSL_OP_FOO |
function id | OSSL_FUNC_FOO_FUNCTION_NAME |
function "name" | OSSL_FUNC_foo_function_name |
function typedef | OSSL_FUNC_foo_function_name_fn |

This splits up all the providers/common/der/*.c.in so the generated
portion is on its own and all related DER writing routines are in
their own files. This also ensures that the DIGEST consstants aren't
reproduced in several files (resulting in symbol clashes).
Finally, the production of OID macros is moved to the generated header
files, allowing other similar macros, or DER constant arrays, to be
built on top of them.

A provider could be linked against a different version of libcrypto than
the version of libcrypto that loaded the provider. Different versions of
libcrypto could define opaque types differently. It must never occur that
a type created in one libcrypto is used directly by the other libcrypto.
This will cause crashes.
We can "cheat" for "built-in" providers that are part of libcrypto itself,
because we know that the two libcrypto versions are the same - but not for
other providers.
To ensure this does not occur we use different types names for the handful
of opaque types that are passed between the core and providers.

The problem encountered is that some arrays were deemed unnecessary by
clang, for example:
providers/common/der/der_rsa.c:424:28: error: variable 'der_aid_sha224Identifier' is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
static const unsigned char der_aid_sha224Identifier[] = {
^
However, these arrays are used in sizeof() expressions in other parts
of the code that's actually used, making that warning-turned-error a
practical problem. We solve this by making the array non-static,
which guarantees that the arrays will be emitted, even though
unnecessarily. Fortunately, they are very small.

The provider context structure is made to include the following information:
- The core provider handle (first argument to the provider init
function). This handle is meant to be used in all upcalls that need
it.
- A library context, used for any libcrypto calls that need it, done in
the provider itself.
Regarding the library context, that's generally only needed if the
provider makes any libcrypto calls, i.e. is linked with libcrypto. That
happens to be the case for all OpenSSL providers, but is applicable for
other providers that use libcrypto internally as well.
The normal thing to do for a provider init function is to create its own
library context. For a provider that's meant to become a dynamically
loadable module, this is what MUST be done.
However, we do not do that in the default provider; it uses the library
context associated with the core provider handle instead. This is
permissible, although generally discouraged, as long as the provider in
question is guaranteed to be built-in, into libcrypto or into the
application that uses it.

We have an old OID database that's not as readable as would be
desired, and we have spots with hand coded DER for well known OIDs.
The perl modules added here give enough support that we can parse
OBJECT IDENTIFIER definitions and encode them as DER.
OpenSSL::OID is a general OID parsing and encoding of ASN.1
definitions, and supports enough of the X.680 syntax to understand
what we find in RFCs and similar documents and produce the DER
encoding for them.
oids_to_c is a specialized module to convert the DER encoding from
OpenSSL::OID to C code. This is primarily useful in file templates
that are processed with util/dofile.pl.

In TLSv1.2 a pre-master secret value is passed from the client to the
server encrypted using RSA PKCS1 type 2 padding in a ClientKeyExchange
message. As well as the normal formatting rules for RSA PKCA1 type 2
padding TLS imposes some additional rules about what constitutes a well
formed key. Specifically it must be exactly the right length and
encode the TLS version originally requested by the client (as opposed to
the actual negotiated version) in its first two bytes.
All of these checks need to be done in constant time and, if they fail,
then the TLS implementation is supposed to continue anyway with a random
key (and therefore the connection will fail later on). This avoids
padding oracle type attacks.
This commit implements this within the RSA padding code so that we keep
all the constant time padding logic in one place. A later commit will
remove it from libssl.

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.
