e077455e9e 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.

This required a great deal of refactoring of crypto/pem/pvkfmt.c, to

use.

e77c13f8b7 MSBLOB & PVK: Make it possible to write EVP_PKEYs with provided internal key
So far, the MSBLOB and PVK writers could only handle EVP_PKEYs with
legacy internal keys.

Specially to be able to compile the loader_attic engine, we use the C
macro OPENSSL_NO_PROVIDER_CODE to avoid building the provider specific
things when we don't need them.  The alternative is to suck half of
crypto/evp/ into loader_attic, and that's just not feasible.

a158f8cfb9 PEM: Unlock MSBLOB and PVK functions from 'no-dsa' and 'no-rc4'
All these functions are usable with RSA keys, there's no reason why
they should be unaccessible when DSA or RC4 are disabled.

When DSA is disabled, it's not possible to use these functions for
DSA EVP_PKEYs.  That's fine, and supported.

When RC4 is disabled, it's not possible to use these functions to
write encrypted PVK output.  That doesn't even depend on the
definition of OPENSSL_NO_RC4, but if the RC4 algorithm is accessible
via EVP, something that isn't known when building libcrypto.

de0799b0fc PEM: constify PEM_write_ routines
There's no reason why the object to be written, or the key string

This makes the IMPLEMENT_PEM_..._const and  DECLARE_PEM_..._const
macros superfluous, so we keep them around but mark them deprecated.

In all places where IMPLEMENT_PEM_..._const and  DECLARE_PEM_..._const
are used, they are replaced with the corresponding macros without
'_const'.

However this is an rarely used format and private key files do not
