f844f9eb44 Rename FIPS_MODE to FIPS_MODULE
This macro is used to determine if certain pieces of code should
become part of the FIPS module or not.  The old name was confusing.

738ee1819e Fix DH_get_nid() so that it does not cache values.
DH_set0_pqg() is now responsible for caching the nid, q and length.

DH with or without named safe prime groups now default to using the maximum private key length (BN_num_bits(q) - 1)
when generating a DH private key. The code is now shared between fips and non fips mode for DH key generation.

The OSSL_PKEY_PARAM_DH_PRIV_LEN parameter can be used during keygen to override the maximum private key length to be
in the range (2 * strength ... bits(q) - 1). Where the strength depends on the length of p.

Added q = (p - 1) / 2 safe prime BIGNUMS so that the code is data driven (To simplify adding new names).
The BIGNUMS were code generated.

Fix error in documented return value for DH_get_nid

629c72db5f When calling the import_to function pass the libctx too
Previously import_to just took an EVP_PKEY as the argument. However we
need to some additional context data as well - specifically the libctx.
Therefore we pass an EVP_PKEY_CTX instead to hold the combination of
both of these things.

The EC export_to function calls EC_POINT_point2buf that can later

BN_CTX associated with the library context. This means we have to change

0abae1636d EVP: Implement support for key downgrading in backends
Downgrading EVP_PKEYs from containing provider side internal keys to
containing legacy keys demands support in the EVP_PKEY_ASN1_METHOD.

This became a bit elaborate because the code would be almost exactly
the same as the import functions int EVP_KEYMGMT.  Therefore, we end
up moving most of the code to common backend support files that can be
used both by legacy backend code and by our providers.

0996cff91f DH, DSA, EC_KEY: Fix exporters to allow domain parameter keys
The export-to-provider functions for DH, DSA and EC_KEY assumed that a
public key is always present, and would fail if not.  This blocks any
attempt to export a key structure with only domain parameters.

While fixing this, we also modify the selection declaration to
evp_keymgmt_import() to be more adaptive, the diverse selection bits
are now added when the corresponding data is added to the OSSL_PARAM
array.

df13defd4f EVP: Check that key methods aren't foreign when exporting
The EVP_PKEY_ASN1_METHOD function export_to() must check that the key
we're trying to export has a known libcrypto method, i.e. is a built
in RSA_METHOD, DSA_METHOD, etc.  Otherwise, the method may be defined
by the calling application, by an engine, by another library, and we
simply cannot know all the quirks hidden behind that method, if we
have access to the key data, or much anything.

Such keys are simply deemed impossible to export to provider keys,
i.e. have export_to() return 0.  This cascades back to functions like
evp_pkey_export_to_provider() and evp_pkey_upgrade_to_provider() and
their callers.  In most cases, this is fine, but if these get mixed in
with provider side keys in any function, that function will fail.

b305452f69 Redesign the KEYMGMT libcrypto <-> provider interface - the basics
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)

Fixes #10979

local header files, which are located next to source files in the source

25f2138b0a Reorganize private crypto header files
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.
