We use a fake EVP_KEYMGMT import function with the newly modified
EVP_PKEY_ASN1_METHOD export_to function to pass the exported
OSSL_PARAM array directly to the EVP_PKEY_export() callback instead of
exporting to an actual provided key and then getting the OSSL_PARAM
array from there, just to throw away that key again.

If someone calls an EVP_PKEY_get0*() function then we create a legacy
key and cache it in the EVP_PKEY - but it doesn't become an "origin" and
it doesn't ever get updated. This will be documented as a restriction of

The existing names such as EVP_PKEY_param_fromdata_settable were a bit
confusing since the 'param' referred to key params not OSSL_PARAM. To simplify
the interface a 'selection' parameter will be passed instead. The
changes are:
(1) EVP_PKEY_fromdata_init() replaces both EVP_PKEY_key_fromdata_init() and EVP_PKEY_param_fromdata_init().
(2) EVP_PKEY_fromdata() has an additional selection parameter.
(3) EVP_PKEY_fromdata_settable() replaces EVP_PKEY_key_fromdata_settable() and EVP_PKEY_param_fromdata_settable().
EVP_PKEY_fromdata_settable() also uses a selection parameter.

As long as there are internal legacy keys for EVP_PKEY, we need to preserve
the EVP_PKEY numeric identity when generating a key, and when creating the
EVP_PKEY_CTX.
For added consistency, the EVP_PKEY_CTX contructor tries a little
harder to find a EVP_PKEY_METHOD. Otherwise, we may run into
situations where the EVP_PKEY_CTX ends up having no associated methods
at all.

In EVP_PKEY_METHOD code, the backend initializes ctx->keygen_info.
With provider side code, it's not possible to reach back into the
EVP_PKEY_CTX in the same manner, so we need to make that
initialization in the central generation function, EVP_PKEY_gen().
This isn't quite compatible with the idea that keygen_info could have
an arbitrary amount of elements, but since all our legacy backends use
exactly two elements, that's what we go for.

EVP_PKEY_CTX_gettable_params() was missing code for the keygen operation.
After adding it it was noticed that it is probably not required for this type, so instead
the gen_get_params and gen_gettable_params have been remnoved from the provider interface.
gen_get_params was only implemented for ec to get the curve name. This seems redundant
since normally you would set parameters into the keygen_init() and then generate a key.
Normally you would expect to extract data from the key - not the object that we just set up
to do the keygen.
Added a simple settable and gettable test into a test that does keygen.

The reason to do this is many-fold. We need EC key generation for
other work. However, SM2 are currently closely related to EC keys
with legacy methods, but not with provider methods.
To avoid having to wait on provider support for SM2, we temporarly
do an extra check for what the legacy methods identify as SM2 keys
(either the EVP_PKEY_SM2 pkey id was used, or the SM2 curve), and
redirect to legacy code in one case, and in the other case, we
forcedly downgrade provider side EC keys with SM2 curves to legacy
SM2 keys, using available tools.

Upgrading EVP_PKEYs from containing legacy keys to containing provider
side keys proved to be risky, with a number of unpleasant corner
cases, and with functions like EVP_PKEY_get0_DSA() failing
unexpectedly.
We therefore change course, and instead of upgrading legacy internal
keys to provider side internal keys, we downgrade provider side
internal keys to legacy ones. To be able to do this, we add
|import_from| and make it a callback function designed for
evp_keymgmt_export().
This means that evp_pkey_upgrade_to_provider() is replaced with
evp_pkey_downgrade().
EVP_PKEY_copy_parameters() is the most deeply affected function of
this change.

Instead of fetching the EVP_KEYMGMT in the init for every different
operation, do it when creating the EVP_PKEY_CTX.
This allows certain control functions to be called between the
creation of the EVP_PKEY_CTX and the call of the operation's init
function.
Use case: EVP_PKEY_CTX_set1_id(), which is allowed to be called very
early with the legacy implementation, this should still be allowed

Provide EC serializers for text, pem and der.
EC parameters use ANS1 'CHOICE' - which means they are more embedded than other parameters used by
other KEY types (which normally have a SEQUENCE at the top level).
For this reason the ANS1_STRING type that was being passed around has been changed to a void so that the
code can still be shared with EC.
The EC serializer only supports named curves currently.
NOTE the serializer code assumes PKCS8 format - if the older encode methods are needed they will need to be
added in another PR. (Probably when deserialization is considered).
EVP_PKEY_key_fromdata_init was changed from using a keypair selection to all bits of a key. A side effect of this was
that the very restrictive checks in the ecx code needed to be relaxed as it was assuming all selection flags were non
optional. As this is not the case for any other key the code has been modified.
Fixed a bug in legacy_ctrl_str_to_params() - "ecdh_cofactor_mode" was being incorrectly converted to the wrong keyname.

The KEYMGMT libcrypto <-> provider interface currently makes a few
assumptions:
1. provider side domain parameters and key data isn't mutable. In
other words, as soon as a key has been created in any (loaded,
imported data, ...), it's set in stone.
2. provider side domain parameters can be strictly separated from the
key data.
This does work for the most part, but there are places where that's a
bit too rigid for the functionality that the EVP_PKEY API delivers.
Key data needs to be mutable to allow the flexibility that functions
like EVP_PKEY_copy_parameters promise, as well as to provide the
combinations of data that an EVP_PKEY is generally assumed to be able
to hold:
- domain parameters only
- public key only
- public key + private key
- domain parameters + public key
- domain parameters + public key + private key
To remedy all this, we:
1. let go of the distinction between domain parameters and key
material proper in the libcrypto <-> provider interface.
As a consequence, functions that still need it gain a selection
argument, which is a set of bits that indicate what parts of the
key object are to be considered in a specific call. This allows
a reduction of very similar functions into one.
2. Rework the libcrypto <-> provider interface so provider side key
objects are created and destructed with a separate function, and
get their data filled and extracted in through import and export.
(future work will see other key object constructors and other
functions to fill them with data)

Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:
While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.
To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:
#include "internal/file.h" # located in 'include/internal'
#include "internal/file_int.h" # located in 'crypto/include/internal'
This commit moves the private crypto headers from
'crypto/include/internal' to 'include/crypto'
As a result, the include directives become unambiguous
#include "internal/file.h" # located in 'include/internal'
#include "crypto/file.h" # located in 'include/crypto'
hence the superfluous '_int.h' suffixes can be stripped.
The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.
