Because the libcrypto code has relinquished control of exact words to
express padding mode choices, we re-implement them in the appropriate
provider implementation.
For the sake of legacy controls, we maintain support for the numeric
form of the padding mode, but leave that support otherwise undeclared.

Also Add ability for providers to dynamically exclude cipher algorithms.
Cipher algorithms are only returned from providers if their capable() method is either NULL,
or the method returns 1.
This is mainly required for ciphers that only have hardware implementations.
If there is no hardware support, then the algorithm needs to be not available.

The idea to have all these things in providers/common was viable as
long as the implementations was spread around their main providers.
This is, however, no longer the case, so we move the common blocks
closer to the source that use them.

In TLSv1.2 a pre-master secret value is passed from the client to the
server encrypted using RSA PKCS1 type 2 padding in a ClientKeyExchange
message. As well as the normal formatting rules for RSA PKCA1 type 2
padding TLS imposes some additional rules about what constitutes a well
formed key. Specifically it must be exactly the right length and
encode the TLS version originally requested by the client (as opposed to
the actual negotiated version) in its first two bytes.
All of these checks need to be done in constant time and, if they fail,
then the TLS implementation is supposed to continue anyway with a random
key (and therefore the connection will fail later on). This avoids
padding oracle type attacks.
This commit implements this within the RSA padding code so that we keep
all the constant time padding logic in one place. A later commit will
remove it from libssl.

EVP_CIPHER_CTX_set_keylen() was succeeding even though a bad key length
is passed to it. This is because the set_ctx_params() were all accepting
this parameter and blindly changing the keylen even though the cipher did
not accept a variable key length. Even removing this didn't entirely
resolve the issue because set_ctx_params() functions succeed even if
passed a parameter they do not recognise.
This should fix various issues found by OSSfuzz/Cryptofuzz.

Fixes#10438
issue found by clusterfuzz/ossfuzz
The dest was getting a copy of the src structure which contained a pointer that should point to an offset inside itself - because of the copy it was pointing to the original structure.
The setup for a ctx is mainly done by the initkey method in the PROV_CIPHER_HW structure. Because of this it makes sense that the structure should also contain a copyctx method that is use to resolve any pointers that need to be setup.
A dup_ctx has been added to the cipher_enc tests in evp_test. It does a dup after setup and then frees the original ctx. This detects any floating pointers in the duplicated context that were pointing back to the freed ctx.

Previous macros suggested that from 3.0, we're only allowed to
deprecate things at a major version. However, there's no policy
stating this, but there is for removal, saying that to remove
something, it must have been deprecated for 5 years, and that removal
can only happen at a major version.
Meanwhile, the semantic versioning rule is that deprecation should
trigger a MINOR version update, which is reflected in the macro names
as of this change.

However, providers/common/digests/digest_common.c stays where it is,
because it's support code rather than an implementation.
To better support all kinds of implementations with common code, we
add the library providers/libcommon.a. Code that ends up in this
library must be FIPS agnostic.
While we're moving things around, though, we move digestscommon.h
from providers/common/include/internal to providers/common/include/prov,
thereby starting on a provider specific include structure, which
follows the line of thoughts of the recent header file reorganization.

Currently, there are two different directories which contain internal
header files of libcrypto which are meant to be shared internally:
While header files in 'include/internal' are intended to be shared
between libcrypto and libssl, the files in 'crypto/include/internal'
are intended to be shared inside libcrypto only.
To make things complicated, the include search path is set up in such
a way that the directive #include "internal/file.h" could refer to
a file in either of these two directoroes. This makes it necessary
in some cases to add a '_int.h' suffix to some files to resolve this
ambiguity:
#include "internal/file.h" # located in 'include/internal'
#include "internal/file_int.h" # located in 'crypto/include/internal'
This commit moves the private crypto headers from
'crypto/include/internal' to 'include/crypto'
As a result, the include directives become unambiguous
#include "internal/file.h" # located in 'include/internal'
#include "crypto/file.h" # located in 'include/crypto'
hence the superfluous '_int.h' suffixes can be stripped.
The files 'store_int.h' and 'store.h' need to be treated specially;
they are joined into a single file.

With some provider implementations, there are underlying ciphers,
digests and macs. For some of them, the name was retrieved from the
method, but since the methods do not store those any more, we add
different mechanics.
For code that needs to pass on the name of a cipher or diges via
parameters, we simply locally store the name that was used when
fetching said cipher or digest. This will ensure that any underlying
code that needs to fetch that same cipher or digest does so with the
exact same name instead of any random name from the set of names
associated with the algorithm.
For code that needs to check what kind of algorithm was passed, we
provide EVP_{type}_is_a(), that returns true if the given method has
the given name as one of its names.
