This makes it possible to generate SM2 parameters and keys like this:
EVP_PKEY_CTX *pctx = EVP_PKEY_CTX_new_id(EVP_PKEY_SM2);
EVP_PKEY *pkey = EVP_PKEY_new();
EVP_PKEY_keygen_init(pctx);
EVP_PKEY_keygen(pctx, pkey);

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.

The output C code was made to use ERR_func_error_string() to see if a
string table was already loaded or not. Since this function returns
NULL always, this check became useless.
Change it to use ERR_reason_error_string() instead, as there's no
reason to believe we will get rid of reason strings, ever.
To top it off, we rebuild all affected C sources.

Some signature algorithms require special treatment for digesting, such
as SM2. This patch adds the ability of handling raw input data in
apps/pkeyutl other than accepting only pre-hashed input data.
Beside, SM2 requries an ID string when signing or verifying a piece of data,
this patch also adds the ability for apps/pkeyutil to specify that ID
string.

Currently, critical bugs prevent using SM2 signatures through the
`EVP_PKEY` interface: any application that managed to satisfy the
requirement of forcing SM3 as the message digest – even if this is
currently not possible transparently through the `EVP_PKEY` interface
and requires manually forcing the MD selection – would crash with a
segmentation fault upon calling the `SM2_sign()` function.
This is easily verified using the OpenSSL CLI to execute this critical
code path under the right conditions:
`openssl dgst -sm3 -hex -sign sm2.eckey /path/to/file/to/sign`
The issue is caused by a double free at the end of `SM2_sign()` in
`crypto/sm2/sm2_sign.c` in case of successful signature generation.
In addition, even if the double free was not causing segfaults,
the function returns the wrong return value in case of success (it
would return 0 rather than 1).
This patch fixes both problems.
