rand_lib.c: fix null pointer dereferences after RAND_get_rand_method() failure

RAND_get_rand_method() can return a NULL method pointer in the case of a
malloc failure, so don't dereference it without a check.

Optimize AES-ECB mode in OpenSSL for both aarch64 and aarch32

Aes-ecb mode can be optimized by inverleaving cipher operation on
several blocks and loop unrolling. Interleaving needs one ideal
unrolling factor, here we adopt the same factor with aes-cbc,
which is described as below:
    If blocks number > 5, select 5 blocks as one iteration,every
    loop, decrease the blocks number by 5.
    If 3 < left blocks < 5 select 3 blocks as one iteration, every
    loop, decrease the block number by 3.
    If left blocks < 3, treat them as tail blocks.
Detailed implementation will have a little adjustment for squeezing
code space.
With this way, for small size such as 16 bytes, the performance is
similar as before, but for big size such as 16k bytes, the performance
improves a lot, even reaches to 100%, for some arches such as A57,
the improvement  even exceeds 100%. The following table will list the
encryption performance data on aarch64, take a72 and a57 as examples.
Performance value takes the unit of cycles per byte, takes the format
as comparision of values. List them as below:

Teach the RSA implementation about TLS RSA Key Transport

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

SERIALIZER: add support for serializing EVP_PKEYs

The following public functions is added:

- OSSL_SERIALIZER_CTX_new_by_EVP_PKEY()
- OSSL_SERIALIZER_CTX_set_cipher()
- OSSL_SERIALIZER_CTX_set_passphrase()
- OSSL_SERIALIZER_CTX_set_passphrase_cb()
- OSSL_SERIALIZER_CTX_set_passphrase_ui()

OSSL_SERIALIZER_CTX_new_by_EVP_PKEY() selects a suitable serializer
for the given EVP_PKEY, and sets up the OSSL_SERIALIZER_CTX to
function together with OSSL_SERIALIZER_to_bio() and
OSSL_SERIALIZER_to_fp().

OSSL_SERIALIZER_CTX_set_cipher() indicates what cipher should be used
to produce an encrypted serialization of the EVP_PKEY.  This is passed
directly to the provider using OSSL_SERIALIZER_CTX_set_params().

OSSL_SERIALIZER_CTX_set_passphrase() can be used to set a pass phrase

OSSL_SERIALIZER_CTX_set_passphrase_cb() and
OSSL_SERIALIZER_CTX_set_passphrase_ui() sets up a callback to be used
to prompt for a passphrase.  This is stored in the context, and is

SERIALIZER: New API for serialization of objects through providers

Serialization is needed to be able to take a provider object (such as
the provider side key data) and output it in PEM form, DER form, text
form (for display), and possibly other future forms (XML? JSON? JWK?)

The idea is that a serializer should be able to handle objects it has
intimate knowledge of, as well as object data in OSSL_PARAM form.  The
latter will allow libcrypto to serialize some object with a different
provider than the one holding the data, if exporting of that data is
allowed and there is a serializer that can handle it.

We will provide serializers for the types of objects we know about,
which should be useful together with any other provider that provides
implementations of the same type of object.

Serializers are selected by method name and a couple of additional
properties:

- format        used to tell what format the output should be in.
                Possibilities could include "format=text",
                "format=pem", "format=der", "format=pem-pkcs1"
                (traditional), "format=der-pkcs1" (traditional)
- type          used to tell exactly what type of data should be
                output, for example "type=public" (the public part of
                a key), "type=private" (the private part of a key),
                "type=domainparams" (domain parameters).

This also adds a passphrase callback function type,
OSSL_PASSPHRASE_CALLBACK, which is a bit like OSSL_CALLBACK, but it
takes a few extra arguments to place the result in.

chacha/asm/chacha-armv8.pl: preserve FP registers d8 and d9 correctly

Depending on the size of the input, we may take different paths through
the accelerated arm64 ChaCha20 routines, each of which use a different
subset of the FP registers, some of which need to be preserved and
restored, as required by the AArch64 calling convention (AAPCS64)

In some cases, (e.g., when the input size is 640 bytes), we call the 512
byte NEON path followed directly by the scalar path, and in this case,
we preserve and restore d8 and d9, only to clobber them again
immediately before handing over to the scalar path which does not touch
the FP registers at all, and hence does not restore them either.

Fix this by moving the restoration of d8 and d9 to a later stage in the
512 byte routine, either before calling the scalar path, or when exiting
the function.

Fix a race condition in SNI handling

As was done for ciphers, supported groups, and EC point formats in
https://github.com/openssl/openssl/pull/9162, only write the negotiated
SNI hostname value to the session object when not resuming, even for
TLS 1.3 resumptions.  Otherwise, when using a stateful session cache
(as is done by default when 0-RTT data is enabled), we can have multiple
SSLs active using the same in-memory session object, which leads to
double-frees and similar race conditions in the SNI handler prior
to this commit.

Fortunately, since draft-ietf-tls-tls13-22, there is no requirement
that the SNI hostname be preserved across TLS 1.3 resumption, and thus
not a need to continually update the session object with the "current"
value (to be used when producing session tickets, so that the subsequent
resumption can be checked against the current value).  So we can just
relax the logic and only write to the session object for initial handshakes.
This still leaves us in a somewhat inconsistent state, since if the SNI value
does change across handshakes, the session object will continue to record
the initial handshake's value, even if that bears no relation to the
current handshake.  The current SSL_get_servername() implementation
prefers the value from the session if s->hit, but a more complete fix
for that and related issues is underway in
https://github.com/openssl/openssl/pull/10018; there is no need to wait
for the complete fix for SNI name handling in order to close the
race condition and avoid runtime crashes.

This also affects the way legacy NIDs are looked up in
evp_cipher_from_dispatch() and evp_md_from_dispatch().  Instead of
trying to find the NID directly, look up the legacy method structure
and grab the NID from there.  The reason is that NIDs can be aliases
for other NIDs, which looks like a clash even if wasn't really one.
