So far, decoder implementations would return true (1) for a successful
decode all the way, including what the callback it called returned,
and false (0) in all other cases.
This construction didn't allow to stop to decoding process on fatal
errors, nor to choose what to report in the provider code.
This is now changed so that decoders implementations are made to
return false only on errors that should stop the decoding process from
carrying on with other implementations, and return true for all other
cases, even if that didn't result in a constructed object (EVP_PKEY
for example), essentially making it OK to return "empty handed".
The success of the decoding process is now all about successfully
constructing the final object, rather than about the return value of
the decoding chain. If no construction is attempted, the central
decoding processing code concludes that whatever the input consisted
of, it's not supported by the available decoder implementations.

Change things so that passing NULL to OSSL_LIB_CTX_set0_default() means
keep the current library context unchanged.
This has the advantage of simplifying error handling, e.g. you can call
OSSL_LIB_CTX_set0_default in an error/finalisation block safe in the
knowledge the if the "prevctx" was never set then it will be a no-op (like
calling a "free" function with NULL).

Add a "where did this EVP_{CIPHER,MD} come from" flag: global, via fetch,
or via EVP_{CIPHER,MD}_meth_new. Update EVP_{CIPHER,MD}_free to handle all
three origins. The flag is deliberately right before some function pointers,
so that compile-time failures (int/pointer) will occur, as opposed to
taking a bit in the existing "flags" field. The "global variable" flag
is non-zero, so the default case of using OPENSSL_zalloc (for provider
ciphers), will do the right thing. Ref-counting is a no-op for
Make up_ref no-op for global MD and CIPHER objects
Deprecate EVP_MD_CTX_md(). Added EVP_MD_CTX_get0_md() (same semantics as
the deprecated function) and EVP_MD_CTX_get1_md(). Likewise, deprecate
EVP_CIPHER_CTX_cipher() in favor of EVP_CIPHER_CTX_get0_cipher(), and add
EVP_CIPHER_CTX_get1_CIPHER().
Refactor EVP_MD_free() and EVP_MD_meth_free() to call new common
evp_md_free_int() function.
Refactor EVP_CIPHER_free() and EVP_CIPHER_meth_free() to call new common
evp_cipher_free_int() function.
Also change some flags tests to explicit test == or != zero. E.g.,
if (flags & x) --> if ((flags & x) != 0)
if (!(flags & x)) --> if ((flags & x) == 0)
Only done for those lines where "get0_cipher" calls were made.

Compliance with IG 9.4 requires that an inverse cipher function be
tested if one is implemented. Just running AES_GCM encrypt/decrypt does not meet this
requirement (Since only ECB, CBC, XTS, KW, KWP support the inverse
function during decryption mode).
Added a mode to the cipher test so that the AES_GCM only does an encrypt
and AES_ECB only does a decrypt. TDES still does both.

OTC recently voted that EVP_PKEY types will be immutable in 3.0. This
means that EVP_PKEY_set_alias_type can no longer work and should be
removed entirely (applications will need to be rewritten not to use it).
It was primarily used for SM2 which no longer needs this call.
Applications should generate SM2 keys directly (without going via an EC
key first), or otherwise when loading keys they should automatically be
detected as SM2 keys.

These functions are prerequisites for implementing EVP_PKEY_todata().
OSSL_PARAM_dup() is required to make a deep copy of the exported
params (since the provider export() uses a OSSL_PARAM_BLD which throws away the
data after the call), and then use OSSL_PARAM_merge() to add some additional params
that can be passed to the EVP_PKEY_todata().
