8ae40cf57d ENCODER: Refactor provider implementations, and some cleanup
The encoder implementations were implemented by unnecessarily copying
code into numerous topical source files, making them hard to maintain.
This changes merges all those into two source files, one that encodes
into DER and PEM, the other to text.

Diverse small cleanups are included.

63f187cfed STORE: Add a built-in 'file:' storemgmt implementation (loader)
This replaces the older 'file:' loader that is now an engine.

It's still possible to use the older 'file:' loader by explicitly
using the engine, and tests will remain for it as long as ENGINEs are
still supported (even through deprecated).

To support this storemgmt implementation, a few internal OSSL_DECODER
modifications are needed:

-   An internal function that implements most of
    OSSL_DECODER_CTX_new_by_EVP_PKEY(), but operates on an already
    existing OSSL_DECODER_CTX instead of allocating a new one.
-   Allow direct creation of a OSSL_DECODER from an OSSL_ALGORITHM.
    It isn't attached to any provider, and is only used internally, to
    simply catch any DER encoded object to be passed back to the
    object callback with no further checking.  This implementation
    becomes the last resort decoder, when all "normal"
    decodation attempts (i.e. those that are supposed to result
    in an OpenSSL object of some sort) have failed.

Because file_store_attach() uses BIO_tell(), we must also support
BIO_ctrl() as a libcrypto upcall.

9f7bdcf37f Add ERR_raise() errors to fips OSSL_provider_init and self tests.
As the ERR_raise() is setup at this point returng a range of negative values for errors is not required.
This will need to be revisited if the code ever moves to running from the DEP.
Added a -config option to the fips install so that it can test if a fips module is loadable from configuration.
(The -verify option only uses the generated config, whereas -config uses the normal way of including the generated data via another config file).
Added more failure tests for the raised errors.

e0137ca92b [EC][ASN1] Detect missing OID when serializing EC parameters and keys
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`.

Fixes #12306

363b1e5dae Make the naming scheme for dispatched functions more consistent
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    |
  function ptr getter  | OSSL_FUNC_foo_function_name       |

d40b42ab4c Maintain strict type discipline between the core and providers
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.

05aa8790ac PROV: Add a proper provider context structure for OpenSSL providers
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.

If there is no hardware support, then the algorithm needs to be not available.

d9a7510747 Teach the RSA implementation about TLS RSA Key Transport
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.

d23adad113 EVP_CIPHER_CTX_set_keylen should not succeed if a bad keylen is passed
EVP_CIPHER_CTX_set_keylen() was succeeding even though a bad key length
is passed to it. This is because the set_ctx_params() were all accepting
this parameter and blindly changing the keylen even though the cipher did
not accept a variable key length. Even removing this didn't entirely
resolve the issue because set_ctx_params() functions succeed even if
passed a parameter they do not recognise.

This should fix various issues found by OSSfuzz/Cryptofuzz.

f75abcc0f0 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.
