Add an option to configuration files "config_diagnostics" that when set to a

34b80d0622 STORE: Modify to support loading with provider based loaders
This adds the needed code to make the OSSL_STORE API functions handle
provided STORE implementations.

This also modifies OSSL_STORE_attach() for have the URI, the
library context and the properties in the same order as
OSSL_STORE_open_with_libctx().

The most notable change, though, is how this creates a division of
labor between libcrypto and any storemgmt implementation that wants to
pass X.509, X.509 CRL, etc structures back to libcrypto.  Since those
structures aren't directly supported in the libcrypto <-> provider
interface (asymmetric keys being the only exception so far), we resort
to a libcrypto object callback that can handle passed data in DER form
and does its part of figuring out what the DER content actually is.

This also adds the internal x509_crl_set0_libctx(), which works just
like x509_set0_libctx(), but for X509_CRL.

ab00ddb559 OSSL_PARAM: Add string pointer getters
When some function receives an OSSL_PARAM array to pilfer for data,
and there is a string of some sort, and all the code needs is to get
the pointer to the data, rather than a copy, there is currently no
other way than to use |param->data| directly.  This is of course a
valid method, but lacks any safety check (is |param->data_type|
correct, for example?).

OSSL_PARAM_get_utf8_string_ptr() and OSSL_PARAM_get_octet_string_ptr()
helps the programmer with such things, by setting the argument pointer
to |param->data|.
Additionally, the handle the data types OSSL_PARAM_UTF8_PTR and
OSSL_PARAM_OCTET_PTR as well.

14c8a3d118 CORE: Define provider-native abstract objects
This is placed as CORE because the core of libcrypto is the authority
for what is possible to do and what's required to make these abstract
objects work.

In essence, an abstract object is an OSSL_PARAM array with well
defined parameter keys and values:

-   an object type, which is a number indicating what kind of
    libcrypto structure the object in question can be used with.  The
    currently possible numbers are defined in <openssl/core_object.h>.
-   an object data type, which is a string that indicates more closely
    what the contents of the object are.
-   the object data, an octet string.  The exact encoding used depends
    on the context in which it's used.  For example, the decoder
    sub-system accepts any encoding, as long as there is a decoder
    implementation that takes that as input.  If central code is to
    handle the data directly, DER encoding is assumed. (*)
-   an object reference, also an octet string.  This octet string is
    not the object contents, just a mere reference to a provider-native
    object. (**)
-   an object description, which is a human readable text string that
    can be displayed if some software desires to do so.

The intent is that certain provider-native operations (called X
here) are able to return any sort of object that belong with other
operations, or an object that has no provider support otherwise.

(*) A future extension might be to be able to specify encoding.

(**) The possible mechanisms for dealing with object references are:

-   An object loading function in the target operation.  The exact
    target operation is determined by the object type (for example,
    OSSL_OBJECT_PKEY implies that the target operation is a KEYMGMT)
    and the implementation to be fetched by its object data type (for
    an OSSL_OBJECT_PKEY, that's the KEYMGMT keytype to be fetched).
    This loading function is only useful for this if the implementations
    that are involved (X and KEYMGMT, for example) are from the same
    provider.

-   An object exporter function in the operation X implementation.
    That exporter function can be used to export the object data in
    OSSL_PARAM form that can be imported by a target operation's
    import function.  This can be used when it's not possible to fetch
    the target operation implementation from the same provider.

2274d22d39 STORE: Distinguish public keys from private keys
While public keys and private keys use the same type (EVP_PKEY), just
with different contents, callers still need to distinguish between the
two to be able to know what functions to call with them (for example,
to be able to choose between EVP_PKEY_print_private() and
EVP_PKEY_print_public()).
The OSSL_STORE backend knows what it loaded, so it has the capacity to
inform.

Note that the same as usual still applies, that a private key EVP_PKEY
contains the public parts, but not necessarily the other way around.

ebe3f24b3d provider: disable fall-backs if OSSL_PROVIDER_load() fails.
If an attempt is made to load a provider and it fails, the fall-back mechanism
should be disabled to prevent the user getting some weird happening.  E.g. a
failure to load the FIPS provider should not allow the default to load as a
fall-back.

The OSSL_PROVIDER_try_load() call has been added, to allow a provider to be
loaded without disabling the fall-back mechanism if it fails.

04cb5ec0b7 Add 'on demand self test' and status test to providers
The default and legacy providers currently return 1 for status and self test checks.
Added test to show the 3 different stages the self test can be run (for installation, loading and on demand).

For the fips provider:
  - If the on demand self test fails, then any subsequent fetches should also fail. To implement this the
    cached algorithms are flushed on failure.
  - getting the self test callback in the fips provider is a bit complicated since the callback hangs off the core
    libctx (as it is set by the application) not the actual fips library context. Also the callback can be set at
    any time not just during the OSSL_provider_init() so it is calculated each time before doing any self test.

7d615e2178 rand_drbg: remove RAND_DRBG.
The RAND_DRBG API did not fit well into the new provider concept as
implemented by EVP_RAND and EVP_RAND_CTX. The main reason is that the
RAND_DRBG API is a mixture of 'front end' and 'back end' API calls
and some of its API calls are rather low-level. This holds in particular
for the callback mechanism (RAND_DRBG_set_callbacks()) and the RAND_DRBG
type changing mechanism (RAND_DRBG_set()).

Adding a compatibility layer to continue supporting the RAND_DRBG API as
a legacy API for a regular deprecation period turned out to come at the
price of complicating the new provider API unnecessarily. Since the
RAND_DRBG API exists only since version 1.1.1, it was decided by the OMC
to drop it entirely.

Other related changes:

Use RNG instead of DRBG in EVP_RAND documentation.  The documentation was
using DRBG in places where it should have been RNG or CSRNG.

Move the RAND_DRBG(7) documentation to EVP_RAND(7).

4701f0a9a0 DESERIALIZER: Rethink password handling
The OSSL_DESERIALIZER API makes the incorrect assumption that the
caller must cipher and other pass phrase related parameters to the
individual desserializer implementations, when the reality is that
they only need a passphrase callback, and will be able to figure out
the rest themselves from the input they get.

We simplify it further by never passing any explicit passphrase to the
provider implementation, and simply have them call the passphrase
callback unconditionally when they need, leaving it to libcrypto code
to juggle explicit passphrases, cached passphrases and actual
passphrase callback calls.

072a9fde7d SERIALIZER: Add functions to deserialize into an EVP_PKEY
EVP_PKEY is the fundamental type for provider side code, so we
implement specific support for it, in form of a special context
constructor.

This constructor looks up and collects all available KEYMGMT
implementations, and then uses those names to collect deserializer
implementations, as described in the previous commit.

c3e4c1f325 DESERIALIZER: Add foundation for deserializers
This adds a method OSSL_DESERIALIZER, a deserializer context and basic
support to use a set of serializers to get a desired type of data, as
well as deserializer chains.

The idea is that the caller can call OSSL_DESERIALIZER_CTX_add_serializer()
to set up the set of desired results, and to add possible chains, call
OSSL_DESERIALIZER_CTX_add_extra().  All these deserializers are pushed
on an internal stack.

The actual deserialization is then performed using functions like
OSSL_DESERIALIZER_from_bio().  When performing deserialization, the
inernal stack is walked backwards, keeping track of the deserialized
data and its type along the way, until the data kan be processed into
the desired type of data.

6725682d77 Add X509 related libctx changes.
- In order to not add many X509_XXXX_with_libctx() functions the libctx and propq may be stored in the X509 object via a call to X509_new_with_libctx().
- Loading via PEM_read_bio_X509() or d2i_X509() should pass in a created cert using X509_new_with_libctx().
- Renamed some XXXX_ex() to XXX_with_libctx() for X509 API's.
- Removed the extra parameters in check_purpose..
- X509_digest() has been modified so that it expects a const EVP_MD object() and then internally it does the fetch when it needs to (via ASN1_item_digest_with_libctx()).
- Added API's that set the libctx when they load such as X509_STORE_new_with_libctx() so that the cert chains can be verified.
