Make EVP_PKEY_CTX initialization more precise
There is a vagueness around how the provider data (algorithm name and
property query string) is initialized in the presence of an engine.
This change modifies this slightly so that the algorithm name for use
with providers is never set if the initilization was given an engine.
This makes it easier for other functions to simply check ctx->algorithm
to see if the context is meant to be used for strictly legacy stuff or
not.

Fix OSSL_PARAM_set_BN() to fill the given buffer correctly.
OSSL_PARAM_set_BN() filled the buffer from the left with as many bytes
as that the BIGNUM takes, regardless of buffer size or native
endianness. This was due to BN_bn2nativepad() being given the size of
the BIGNUM rather than the size of the buffer (which meant it never
had to pad anything).

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

Don't abuse the API when that's not what is tested
test_EVP_PKEY_CTX_get_set_params() in test/evp_extra_test.c abused
previously sloppy checking in EVP_PKEY_sign_init_ex(), by passing a
"key to sign with" that was really just domain parameters.
Now that underlying provider import of key payload has become a bit
more strict, that leads to errors, so we need to provide at least a
public part (even though fake), and because this is a signing
operation, a private part as well.

evp_generic_do_all(): fix passing of method data
Method data was passed down as provider to ossl_algorithm_do_all(),
which causes trouble as soon a it's non-NULL. Pass it via the data
structure instead.

Some docs cleanup
Clean up a few manual pages that we're about to touch, according to
conventions found in Linux' man-pages(7); function arguments in
descriptions should be in italics, and types, macros and similar
should be in bold, with the exception for NULL.

For provided ciphers, EVP_CIPHER_CTX_ctrl() with EVP_CTRL_INIT always returns 1
This control command should never be used with provided methods, but
since this is publically available, someone might still make the
mistake. We make sure it returns 1 so as not to be overly
disruptive.

Add EVP_PKEY_CTX_new_provided()
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.
