Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix,
e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER.
The OPENSSL_CTX type stands out a little by using a different prefix.
For consistency reasons, this type is renamed to OSSL_LIB_CTX.

PEM_write_bio_PrivateKey_traditional() didn't handle provider-native
keys very well. Originally, it would simply use the corresponding
encoder, which is likely to output modern PEM (not "traditional").
PEM_write_bio_PrivateKey_traditional() is now changed to try and get a
legacy copy of the input EVP_PKEY, and use that copy for traditional
output, if it has such support.
Internally, evp_pkey_copy_downgraded() is added, to be used when
evp_pkey_downgrade() is too intrusive for what it's needed for.

PEM_write_bio_PrivateKey_traditional() uses i2d_PrivateKey() to do the
actual encoding to DER. However, i2d_PrivateKey() is a generic
function that will do what it can to produce output according to what
the associated EVP_PKEY_ASN1_METHOD offers. If that method offers a
function 'old_priv_encode', which is expected to produce the
"traditional" encoded form, then i2d_PrivateKey() uses that. If not,
i2d_PrivateKey() will go on and used more modern methods, which are
all expected to produce PKCS#8.
To ensure that PEM_write_bio_PrivateKey_traditional() never produces
more modern encoded forms, an extra check that 'old_priv_encode' is
non-NULL is added. If it is NULL, an error is returned.

As described in https://github.com/openssl/openssl/issues/9187, the
loading of PEM certificates sometimes fails if a line of base64
content has the length of a multiple of 254.
The problem is in get_header_and_data(). When such a line with a
length of 254 (or a multiple) has been read, the next read will
only read a newline. Due to this get_header_and_data() expects to be
in the header not in the data area. This commit fixes that by checking
if lines have been read completely or only partially. In case of a
previous partial read, a newline will be ignored.

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.

return true for characters > 127. I.e. they are allowing extended ASCII
characters through which then cause problems. E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably. Likewise letters with diacritical marks can also cause problems.
If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.
The implementation uses a single table with a bit for each of the defined
classes. These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set. They will
work for both signed and unsigned character inputs.
