Fix unbounded memory growth when using no-cached-fetch

When OpenSSL has been compiled with no-cached-fetch we do not cache
algorithms fetched from a provider. When we export an EVP_PKEY to a
provider we cache the details of that export in the operation cache for
that EVP_PKEY. Amoung the details we cache is the EVP_KEYMGMT that we used
for the export. When we come to reuse the key in the same provider that
we have previously exported the key to, we check the operation cache for
the cached key data. However because the EVP_KEYMGMT instance was not
cached then instance will be different every time and we were not
recognising that we had already exported the key to the provider.

This causes us to re-export the key to the same provider everytime the key
is used. Since this consumes memory we end up with unbounded memory growth.

The fix is to be more intelligent about recognising that we have already
exported key data to a given provider even if the EVP_KEYMGMT instance is
different.

Don't take a write lock when freeing an EVP_PKEY

When freeing the last reference to an EVP_PKEY there is no point in
taking the lock for the key. It is the last reference and is being freed
so must only be being used by a single thread.

This should not have been the source of any contention so its unclear to
what extent this will improve performance. But we should not be locking
when we don't need to.

Propagate selection all the way on key export

EVP_PKEY_eq() is used to check, among other things, if a certificate
public key corresponds to a private key. When the private key belongs to
a provider that does not allow to export private keys this currently
fails as the internal functions used to import/export keys ignored the
selection given (which specifies that only the public key needs to be
considered) and instead tries to export everything.

This patch allows to propagate the selection all the way down including
adding it in the cache so that a following operation actually looking
for other selection parameters does not mistakenly pick up an export
containing only partial information.

Stop raising ERR_R_MALLOC_FAILURE in most places

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.

EVP: Reverse the fetch logic in all pkey using functionality

In all initializing functions for functionality that use an EVP_PKEY, the
coded logic was to find an KEYMGMT implementation first, and then try to
find the operation method (for example, SIGNATURE implementation) in the
same provider.

This implies that in providers where there is a KEYMGMT implementation,
there must also be a SIGNATURE implementation, along with a KEYEXCH,
ASYM_CIPHER, etc implementation.

The intended design was, however, the opposite implication, i.e. that
where there is a SIGNATURE implementation, there must also be KEYMGMT.

This change reverses the logic of the code to be closer to the intended
design.

There is a consequence; we now use the query_operation_name function from
the KEYMGMT of the EVP_PKEY given by the EVP_PKEY_CTX (ultimately given by
the application). Previously, we used the query_operation_name function
from the KEYMGMT found alongside the SIGNATURE implementation.

Another minor consequence is that the |keymgmt| field in EVP_PKEY_CTX
is now always a reference to the KEYMGMT of the |pkey| field if that
one is given (|pkey| isn't NULL) and is provided (|pkey->keymgmt|
isn't NULL).

Fix race condition & allow operation cache to grow.

This fixes a race condition where the index to the cache location was found
under a read lock and a later write lock set the cache entry. The issue being
that two threads could get the same location index and then fight each other
over writing the cache entry. The most likely outcome is a memory leak,
however it would be possible to set up an invalid cache entry.

The operation cache was a fixed sized array, once full an assertion failed.
The other fix here is to convert this to a stack. The code is simplified and
it avoids a cache overflow condition.

EVP: Make EVP_PKEY_set_params() increment the dirty count

When the internal key is changed, we must count it as muted, so that
next time the affected key is considered for an operation, it gets
re-exported to the signing provider. In other words, this will clear
the EVP_PKEY export cache when the next export attempt occurs.

This also updates evp_keymgmt_util_export_to_provider() to actually
look at the dirty count for provider native origin keys, and act
appropriately.
