When decoding 0 as the selection means to decode anything
you get.
However when exporting and then importing the key data 0 as
selection is not meaningful.
So we set it to OSSL_KEYMGMT_SELECT_ALL to make the export/import
function export/import everything that we have decoded.

We're always supposed to add the fallback "unsupported" error if we don't
have anything better. However in some cases this wasn't happening because
we were incorrectly setting "flag_construct_called" - even though the

The most expensive part of using a PKEY decoder is the
OSSL_DECODER_CTX_new_for_pkey() call. This builds up all of the decoder
chains, which is a complex and time consuming operation. However, if no
new providers have been loaded/unloaded since the last time it was called
we can expect the same results for the same parameters. Note that this
operation takes place *before* we event parse the data for decoding so it
is not dependent on the parsed data at all.
We introduce a cache for OSSL_DECODER_CTX objects. If we have been called
with the same parameters then we just duplicate an existing
OSSL_DECODER_CTX. This should be significantly faster than creating a new
one every time.
Partially addressed the issue in #15199

Since OPENSSL_malloc() and friends report ERR_R_MALLOC_FAILURE, and
at least handle the file name and line number they are called from,
there's no need to report ERR_R_MALLOC_FAILURE where they are called
directly, or when SSLfatal() and RLAYERfatal() is used, the reason
`ERR_R_MALLOC_FAILURE` is changed to `ERR_R_CRYPTO_LIB`.
There were a number of places where `ERR_R_MALLOC_FAILURE` was reported
even though it was a function from a different sub-system that was
called. Those places are changed to report ERR_R_{lib}_LIB, where
{lib} is the name of that sub-system.
Some of them are tricky to get right, as we have a lot of functions
that belong in the ASN1 sub-system, and all the `sk_` calls or from
the CRYPTO sub-system.
Some extra adaptation was necessary where there were custom OPENSSL_malloc()
wrappers, and some bugs are fixed alongside these changes.

Introducing the concept of reserving the store where a number of
provided operation methods are to be stored.
This avoids racing when constructing provided methods, which is
especially pertinent when multiple threads are trying to fetch the
same method, or even any implementation for the same given operation
type.
This introduces a |biglock| in OSSL_METHOD_STORE, which is separate
from the |lock| which is used for more internal and finer grained
locking.

This mostly entails passing around a provider pointer, and handling
queries that includes a pointer to a provider, where NULL means "any".
This also means that there's a need to pass the provider pointer, not
just down to the cache functions, but also be able to get it from
ossl_method_store_fetch(). To this end, that function's OSSL_PROVIDER
pointer argument is modified to be a pointer reference, so the
function can answer back what provider the method comes from.

In a chain of decoders, the first that specifies an input structure
gets it compared with the structure specified by the user, if there is
one. If they aren't the same, that decoder is skipped.
Because the first structure can appear anywhere along a chain of
decoders, not just the decoders associated with the resulting OpenSSL
type, the code that checked the structure name when building up the
chain of decoders is removed.

When decoding a key and asking the keymgmt to import the key data, it
was told that the key data includes everything. This may not be true,
since the user may have specified a different selection, and some
keymgmts may want to be informed.
Our key decoders' export function, on the other hand, didn't care
either, and simply export anything they could, regardless.
In both cases, the selection that was specified by the user is now
passed all the way.

The responsibility for managing the temporary store for methods from
algorithm implementations flaged "no_store" is moved up to the diverse
method fetching functions. This allows them to allocate it "just in
time", or in other words not at all if there is not such algorithm
implementation.
This makes this temporary store more flexible if it's needed outside
of the core fetching functionality, and slightly faster when this
temporary store isn't necessary at all.
