PR https://github.com/openssl/openssl/pull/10122 introduced changes to
the BN_gcd function and the control logic inside it accessed `g->d[0]`
irrespective of `g->top`.
When BN_add is called, in case the result is zero, `BN_zero` is called.
The latter behaves differently depending on the API compatibility level
flag: normally `g->d[0]` is cleared but in `no-deprecated` builds only
`g->top` is set to zero.
This commit uses bitwise logic to ensure that `g` is treated as zero if
`g->top` is zero, irrespective of `g->d[0]`.

This commit aims at refactoring the `BN_rshift` by making it a wrapper
around `bn_rshift_fixed_top`, in order to match the current design of
`BN_lshift`, as suggested in the discussion at
https://github.com/openssl/openssl/pull/10122#discussion_r332474277 .
As described in the code, by refactoring this function, `BN_rshift`
provides a constant-time behavior for sufficiently[!] zero-padded inputs
under the following assumptions: `|n < BN_BITS2|` or `|n / BN_BITS2|`
being non-secret.
Notice that `BN_rshift` returns a canonical representation of the
BIGNUM, if a `fixed_top` representation is required, the caller should
call `bn_rshift_fixed_top` instead.

This works as much as possible EVP_PKEY_CTX_new_id(), except it takes
data that's relevant for providers, algorithm name and property query
string instead of NID and engine.
Additionally, if EVP_PKEY_CTX_new() or EVP_PKEY_CTX_new_id() was
called, the algorithm name in the EVP_PKEY context will be set to the
short name of the given NID (explicit or the one of the given
EVP_PKEY), thereby giving an easier transition from legacy methods to
provided methods.
The intent is that operations will use this information to fetch
provider methods implicitly as needed.

An unintended consequence of https://github.com/openssl/openssl/pull/9808
is that when an explicit parameters curve is matched against one of the
well-known builtin curves we automatically inherit also the associated
seed parameter, even if the input parameters excluded such
parameter.
This later affects the serialization of such parsed keys, causing their
input DER encoding and output DER encoding to differ due to the
additional optional field.
This does not cause problems internally but could affect external
applications, as reported in
https://github.com/openssl/openssl/pull/9811#issuecomment-536153288
This commit fixes the issue by conditionally clearing the seed field if
the original input parameters did not include it.

EVP_Cipher() would return whatever ctx->cipher->ccipher() returned
with no regard for historical semantics.
We change this to first look if there is a ctx->cipher->ccipher(), and
in that case we treat the implementation as one with a custom cipher,
and "translate" it's return value like this: 0 => -1, 1 => outl, where
|outl| is the output length.
If there is no ctx->cipher->ccipher, we treat the implementation as
one without a custom cipher, call ctx->cipher->cupdate or
ctx->cipher->cfinal depending on input, and return whatever they
return (0 or 1).
Furthermore, we add a small hack in EVP_CIPHER_flags() to check if the
cipher is a provided one, and add EVP_CIPH_FLAG_CUSTOM_CIPHER to the
flags to be returned if there is a cipher->ccipher. That way,
provided implementations never have to set that flag themselves, all
they need to do is to include a OSSL_FUNC_CIPHER_CIPHER function.

Prior to OpenSSL 3.0 EVP_Digest[Sign|Verify|Update were just macros for
EVP_DigestUpdate. They are now separate functions. Unfortunately some
code assumes that EVP_Digest[Sign|Verify]Update is interchangeable with
EVP_DigestUpdate. For example the dgst app uses an MD bio which always
calls EVP_DigestUpdate(). However the dgst app supports signing instead
of digesting and may initialise with EVP_DigestSignInit_ex() instead of
just EVP_DigestInit().
We now detect these differences and redirect to the correct function
where appropriate.
