Don't generate a MAC when using KTLS.

The kernel will generate the MAC when transmitting the frame. Doing
so here causes the MAC to be included as part of the plain text that
the kernel MACs and encrypts. Note that this path is not taken when
using stitched cipher suites.

Fix BIO_get_ktls_send() and BIO_get_ktls_recv() to work again.

This partially reverts 3119ab3c9e6d211c461a245f3744893e17b6c193. In the
case of a simple openssl s_server instance, the bio in s->wbio is a
BIO_TYPE_BUFFER BIO, not BIO_TYPE_SOCKET. This caused all of the checks
to fail breaking KTLS.

The default return value of control methods I have looked it is zero
for unknown control requests, so invoking the control requests should
be returning 0 for non-socket BIOs already.

This does still map the requests to 0 at compile time for the non-KTLS
case so that the compiler can optimize the checks away entirely.

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]`.

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.

[ec_asn1.c] Avoid injecting seed when built-in matches

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.

Use fewer primes for the trial division

When using Miller-Rabin to test for primes, it's can be faster to first

slower again. We reduce the number of trial divisions to a point that
gives better performance.

Building: Add modules with DEPENDs to GENERATEd files

For files GENERATEd from templates (.in files), any perl module (.pm
file) that the file depends on will automatically be used.

This means that these two lines:

    GENERATE[foo]=foo.in
    DEPEND[foo]=whatever.pm

will emit this command in a Makefile (or corresponding):

    foo: foo.in whatever.pm configdata.pm
    $(PERL) -I. -Ipathto -Mwhatever -Mconfigdata $(SRCDIR)/util/dofile.pl \\
        foo.in > foo

Note that configdata.pm is automatically added, since util/dofile.pl
itself depends on it.

Fix EVP_Cipher() for provided cipher implementations

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.

Support calling EVP_DigestUpdate instead of EVP_Digest[Sign|Verify]Update

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.
