EC_POINT_bn2point() rejected BIGNUMs with a zero value.
This behavior indirectly caused failures when converting a point
at infinity through EC_POINT_point2hex() and then back to a point with
EC_POINT_hex2point().
With this change such BIGNUMs are treated like any other and exported to
an octet buffer filled with zero.
It is then EC_POINT_oct2point() (either the default implementation or
the custom one in group->meth->oct2point) to determine if such encoding
maps to a valid point (generally the point at infinity is encoded as
0x00).

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.

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.

Make the include guards consistent by renaming them systematically according

The public header files (in the 'include/openssl' directory) are not changed
in 1.1.1, because it is a stable release.
For the private header files files, the guard names try to match the path
specified in the include directives, with all letters converted to upper case
and '/' and '.' replaced by '_'. An extra 'OSSL_' is added as prefix.

Apart from public and internal header files, there is a third type called
local header files, which are located next to source files in the source
directory. Currently, they have different suffixes like
'*_lcl.h', '*_local.h', or '*_int.h'
This commit changes the different suffixes to '*_local.h' uniformly.

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.

An attack is simple, if the first CMS_recipientInfo is valid but the
second CMS_recipientInfo is chosen ciphertext. If the second
recipientInfo decodes to PKCS #1 v1.5 form plaintext, the correct
encryption key will be replaced by garbage, and the message cannot be
decoded, but if the RSA decryption fails, the correct encryption key is
used and the recipient will not notice the attack.
As a work around for this potential attack the length of the decrypted
key must be equal to the cipher default key length, in case the
certifiate is not given and all recipientInfo are tried out.
The old behaviour can be re-enabled in the CMS code by setting the
CMS_DEBUG_DECRYPT flag.
