From this point on, this engine must be specifically specified.
To replace the internal EMBEDDED hack with something unique for the
new module, functions to create application specific OSSL_STORE_INFO
types were added.
Furthermore, the following function had to be exported:
ossl_do_blob_header()
ossl_do_PVK_header()
asn1_d2i_read_bio()
Finally, evp_pkcs82pkey_int() has become public under a new name,
EVP_PKCS82PKEY_with_libctx()

This adds the needed code to make the OSSL_STORE API functions handle
provided STORE implementations.
This also modifies OSSL_STORE_attach() for have the URI, the
library context and the properties in the same order as
OSSL_STORE_open_with_libctx().
The most notable change, though, is how this creates a division of
labor between libcrypto and any storemgmt implementation that wants to
pass X.509, X.509 CRL, etc structures back to libcrypto. Since those
structures aren't directly supported in the libcrypto <-> provider
interface (asymmetric keys being the only exception so far), we resort
to a libcrypto object callback that can handle passed data in DER form
and does its part of figuring out what the DER content actually is.
This also adds the internal x509_crl_set0_libctx(), which works just
like x509_set0_libctx(), but for X509_CRL.

Just like d2i_PrivateKey() / d2i_PrivateKey_ex(), there's a need to
associate an EVP_PKEY extracted from a PUBKEY to a library context and
a property query string. Without it, a provider-native EVP_PKEY can
only fetch necessary internal algorithms from the default library
context, even though an application specific context should be used.

-Public PKCS7 methods that create a PKCS7 object now have variants that also add a libctx and propq.
This includes PKCS7_new_with_libctx(), PKCS7_sign_with_libctx() and PKCS7_encrypt_with_libctx()
-Added SMIME_read_PKCS7_ex() so that a created PKCS7 object can be passed to the read.
-d2i_PKCS7_bio() has been modified so that after it loads the PKCS7 object it then resolves any subobjects that require
the libctx/propq (such as objects containing X509 certificates).

This should only be called during (or right after) using d2iXXX on a object that contains embedded certificate(s)
that require a non default library context. X509_new_with_libctx() should be used if possible.

- In order to not add many X509_XXXX_with_libctx() functions the libctx and propq may be stored in the X509 object via a call to X509_new_with_libctx().
- Loading via PEM_read_bio_X509() or d2i_X509() should pass in a created cert using X509_new_with_libctx().
- Renamed some XXXX_ex() to XXX_with_libctx() for X509 API's.
- Removed the extra parameters in check_purpose..
- X509_digest() has been modified so that it expects a const EVP_MD object() and then internally it does the fetch when it needs to (via ASN1_item_digest_with_libctx()).
- Added API's that set the libctx when they load such as X509_STORE_new_with_libctx() so that the cert chains can be verified.

If a presumably self-signed cert is last in chain we verify its signature
only if X509_V_FLAG_CHECK_SS_SIGNATURE is set. Upon this request we do the
signature verification, but not in case it is a (non-conforming) self-issued
CA certificate with a key usage extension that does not include keyCertSign.
Make clear when we must verify the signature of a certificate
and when we must adhere to key usage restrictions of the 'issuing' cert.
Add some comments for making internal_verify() easier to understand.
Update the documentation of X509_V_FLAG_CHECK_SS_SIGNATURE accordingly.

Move check that cert signing is allowed from x509v3_cache_extensions() to
where it belongs: internal_verify(), generalize it for proxy cert signing.
Correct and simplify check_issued(), now checking self-issued (not: self-signed).
