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.

The existing pre- and post-condition functions are supposed to check if
methods have already been created and stored, using provider operation
bits. This is supposed to only be done for "permanent" method stores.
However, the way the pre-condition was called, it could not know if the
set of implementations to be stored is likely to end up in a "permanent"
or a temporary store. It needs access to the |no_store| flag returned
by the provider's operation query function, because that call was done
after the pre-condition was called.
This requires a bit of refactoring, primarly of |algorithm_do_this()|,
but also of |ossl_method_construct_precondition()|.

Without this, a provider has no way to know that an application
has finished with the array it returned earlier. A non-caching provider

Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix,
e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER.
The OPENSSL_CTX type stands out a little by using a different prefix.
For consistency reasons, this type is renamed to OSSL_LIB_CTX.

When ossl_provider_query_operation() returned NULL, the post-condition
callback wasn't called, and could make algorithm_do_this() falsely
tell the caller that there was an error. Because of this, a provider
that answered with NULL for a particular operation identity would
effectively block the same query on all following providers.

When a desired algorithm wasn't available, we didn't register anywhere
that an attempt had been made, with the result that next time the same
attempt was made, the whole process would be done again.
To avoid this churn, we register a bit for each operation that has
been queried in the libcrypto provider object, and test it before
trying the same query and method construction loop again.
If course, if the provider has told us not to cache, we don't register
this bit.
