If the DRBG is used within the scope of the FIPS OSSL_provider_init
function then it attempts to register a thread callback via c_thread_start.
However the implementation of c_thread_start assumed that the provider's
provctx was already present. However because OSSL_provider_init is still
running it was actually NULL. This means the thread callback fail to work
correctly and a memory leak resulted.
Instead of having c_thread_start use the provctx as the callback argument
we change the definition of c_thread_start to have an explicit callback
argument to use.

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.

- getting the self test callback in the fips provider is a bit complicated since the callback hangs off the core

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_int.h" # located in 'crypto/include/internal'

As a result, the include directives become unambiguous
#include "internal/file.h" # located in 'include/internal'
#include "crypto/file.h" # located in 'include/crypto'

EVP_MACs can't be constant in a EVP_MAC_CTX, as their reference count

We reserve the upper 8 bits of the reason code for internal OpenSSL
use. This allows our own providers to report errors in form of a
packed number that includes library number, function number and
reason number.
With this, a provider can potentially use any reason number it wants
from 1 to 16777216, although the current error semantics really only
allow 1 to 4095 (because only the lower 12 bits are currently
considered an actual reason code by the ERR subsystem).
A provider can provide a reason string table in form of an array of
ERR_STRING_DATA, with each item containing just the reason code and
the associated string, with the dispatch function numbered
OSSL_FUNC_PROVIDER_GET_REASON_STRINGS matching the type
OSSL_provider_get_reason_strings_fn.
If available, libcrypto will call that function on provider
activation.

Common pattern is that the routines to increment the reference count
are called something_up_ref, not something_upref. Adapt
ossl_provider_upref() accordingly.

If a provider gets unloaded then any thread stop handlers that it had
registered will be left hanging. We should clean them up before tearing
down the provider.

The RAND code needs to know about threads stopping in order to cleanup
local thread data. Therefore we add a callback for libcrypto to tell
providers about such events.

The FIPS module currently has "magic" support to have the library
context become the provider context within the core code, for the FIPS
module's inner provider.
We replace that with a core upcall that returns the library context
associated with a provider object. That way, the FIPS module can
handle the assignment of the inner provider context itself. This
allows the FIPS module (and any other provider module that wishes to
use a similar mechanism) to define for itself what the provider
context is. It's currently simply a pointer to a library context,
but may contain other stuff as well in the future.

OSSL_provider_init() gets another output parameter, holding a pointer
to a provider side context. It's entirely up to the provider to
define the context and what it's being used for. This pointer is
passed back to other provider functions, typically the provider global
get_params and set_params functions, and also the diverse algorithm
context creators, and of course, the teardown function.
With this, a provider can be instantiated more than once, or be
re-loaded as the case may be, while maintaining instance state.

OpenSSL will come with a set of well known providers, some of which
need to be accessible from the start. These are typically built in
providers, or providers that will work as fallbacks.
We do this when creating a new provider store, which means that this
will happen in every library context, regardless of if it's the global
default one, or an explicitely created one.
We keep the data about the known providers we want to make accessible
this way in crypto/provider_predefined.h, which may become generated.
For now, though, we make it simple and edited manually.

To ensure that old applications aren't left without any provider, and
at the same time not forcing any default provider on applications that
know how to deal with them, we device the concept of fallback
providers, which are automatically activated if no other provider is
already activated.
