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

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.

The pass phrase prompter that's part of OSSL_ENCODER and OSSL_DECODER
is really a passphrase callback bridge between the diverse forms of
prompters that exist within OpenSSL: pem_password_cb, ui_method and
OSSL_PASSPHRASE_CALLBACK.
This can be generalised, to be re-used by other parts of OpenSSL, and
to thereby allow the users to specify whatever form of pass phrase
callback they need, while being able to pass that on to other APIs
that are called internally, in the form that those APIs demand.
Additionally, we throw in the possibility to cache pass phrases during
a "session" (we leave it to each API to define what a "session" is).
This is useful for any API that implements discovery and therefore may
need to get the same password more than once, such as OSSL_DECODER and
OSSL_STORE.
