bio printf: Avoid using rounding errors in range check

There is a problem casting ULONG_MAX to double which clang-10 is warning about.
ULONG_MAX typically cannot be exactly represented as a double.  ULONG_MAX + 1
can be and this fix uses the latter, however since ULONG_MAX cannot be
represented exactly as a double number we subtract 65535 from this number,
and the result has at most 48 leading one bits, and can therefore be
represented as a double integer without rounding error.  By adding
65536.0 to this number we achive the correct result, which should avoid the
warning.

The addresses a symptom of the underlying problem: we print doubles via an
unsigned long integer.  Doubles have a far greater range and should be printed
better.

AES CTR-DRGB: performance improvement

Optimize the the AES-based implementation of the CTR_DRBG
construction, see 10.2.1 in [1].
Due to the optimizations, the code may deviate (more) from the
pseudocode in [1], but it is functional equivalence being decisive
for compliance:

"All DRBG mechanisms and algorithms are described in this document
in pseudocode, which is intended to explain functionality.
The pseudocode is not intended to constrain real-world
implementations." [9 in [1]].

The following optimizations are done:

- Replace multiple plain AES encryptions by a single AES-ECB
  encryption of a corresponding pre-initialized buffer, where
  possible.
  This allows platform-specific AES-ECB support to
  be used and reduces the overhead of multiple EVP calls.

- Replace the generate operation loop (which is a counter
  increment followed by a plain AES encryption) by a
  loop which does a plain AES encryption followed by
  a counter increment. The latter loop is just a description
  of AES-CTR, so we replace it by a single AES-CTR
  encryption.
  This allows for platform-specific AES-CTR support to be used
  and reduces the overhead of multiple EVP calls.
  This change, that is, going from a pre- to a post- counter
  increment, requires the counter in the internal state
  to be kept at "+1" (compared to the pseudocode in [1])
  such that it is in the correct state, when a generate
  operation is called.
  That in turn also requires all other operations to be
  changed from pre- to post-increment to keep functional
  equivalence.

Correct alignment calculation in ssl3_setup_write

The alignment calculation in ssl3_setup_write incorrectly results in an
alignment allowance of
(-SSL3_RT_HEADER_LENGTH) & (SSL3_ALIGN_PAYLOAD - 1) bytes. This equals 3
in almost all cases. The maximum alignment actually used in do_ssl3_write
is (SSL3_ALIGN_PAYLOAD - 1). This equals 7 bytes in almost all cases. So
there is a potential to overrun the buffer by up to 4 bytes.

Fortunately, the encryption overhead allowed for is 80 bytes which
consists of 16 bytes for the cipher block size and 64 bytes for the MAC
output. However the biggest MAC that we ever produce is HMAC-384 which is
48 bytes - so we have a headroom of 16 bytes (i.e. more than the 4 bytes
of potential overrun).

Thanks to Nagesh Hegde for reporting this.

Fix PEM certificate loading that sometimes fails

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.

[BN] harden `BN_copy()` against leaks from memory accesses

`BN_copy()` (and indirectly `BN_dup()`) do not propagate the
`BN_FLG_CONSTTIME` flag: the propagation has been turned on and off a
few times in the past years, because in some conditions it has shown
unintended consequences in some code paths.

Without turning the propagation on once more, we can still improve
`BN_copy()` by avoiding to leak `src->top` in case `src` is flagged with
`BN_FLG_CONSTTIME`.
In this case we can instead use `src->dmax` as the number of words
allocated for `dst` and for the `memcpy` operation.

Barring compiler or runtime optimizations, if the caller provides `src`
flagged as const time and preallocated to a public size, no leak should
happen due to the copy operation.

[EC] harden EC_KEY against leaks from memory accesses

We should never leak the bit length of the secret scalar in the key,
so we always set the `BN_FLG_CONSTTIME` flag on the internal `BIGNUM`
holding the secret scalar.

This is important also because `BN_dup()` (and `BN_copy()`) do not
propagate the `BN_FLG_CONSTTIME` flag from the source `BIGNUM`, and
this brings an extra risk of inadvertently losing the flag, even when
the called specifically set it.

The propagation has been turned on and off a few times in the past
years because in some conditions has shown unintended consequences in
some code paths, so at the moment we can't fix this in the BN layer.

In `EC_KEY_set_private_key()` we can work around the propagation by
manually setting the flag after `BN_dup()` as we know for sure that
inside the EC module the `BN_FLG_CONSTTIME` is always treated
correctly and should not generate unintended consequences.

Setting the `BN_FLG_CONSTTIME` flag alone is never enough, we also have
to preallocate the `BIGNUM` internal buffer to a fixed public size big
enough that operations performed during the processing never trigger
a realloc which would leak the size of the scalar through memory
accesses.

Fixed Length
------------

The order of the large prime subgroup of the curve is our choice for
a fixed public size, as that is generally the upper bound for
generating a private key in EC cryptosystems and should fit all valid
secret scalars.

For preallocating the `BIGNUM` storage we look at the number of "words"
required for the internal representation of the order, and we
preallocate 2 extra "words" in case any of the subsequent processing
might temporarily overflow the order length.

Future work
-----------

A separate commit addresses further hardening of `BN_copy()` (and
indirectly `BN_dup()`).

[EC] Constify internal EC_KEY pointer usage

A pair of internal functions related to EC_KEY handling could benefit
from declaring `EC_KEY *` variables as `const`, providing clarity for
callers and readers of the code, in addition to enlisting the compiler
in preventing some mistakes.

(cherry picked from commit cd701de96a147260c2290d85af8a0656120a8ff8)

In master `id2_ECParameters` and most of the ASN1 public functions have
been properly constified in their signature.

Unfortunately this has been deemed not doable in a patch release for
1.1.1 as, in subtle ways, this would break API compatibility.
See the discussion at https://github.com/openssl/openssl/pull/9347 for
more details about this.

This constification commit should still be portable w.r.t. our criteria,
as the constification happens only on internal functions.

The fix here is to explicitly discard the const qualifier before the
call to `i2d_ECParameters`, which should be safe anyway because we can
expect `i2d_ECParameters()` to treat the first argument as if it was
const.

Fix NULL dereference in SSL_check_chain() for TLS 1.3

In the tls1_check_sig_alg() helper function, we loop through the list of
"signature_algorithms_cert" values received from the client and attempt
to look up each one in turn in our internal table that maps wire
codepoint to string-form name, digest and/or signature NID, etc., in
order to compare the signature scheme from the peer's list against what
is used to sign the certificates in the certificate chain we're
checking.  Unfortunately, when the peer sends a value that we don't
support, the lookup returns NULL, but we unconditionally dereference the
lookup result for the comparison, leading to an application crash
triggerable by an unauthenticated client.

Since we will not be able to say anything about algorithms we don't
recognize, treat NULL return from lookup as "does not match".

We currently only apply the "signature_algorithm_cert" checks on TLS 1.3
connections, so previous TLS versions are unaffected.  SSL_check_chain()
is not called directly from libssl, but may be used by the application
inside a callback (e.g., client_hello or cert callback) to verify that a
candidate certificate chain will be acceptable to the client.

Add test that changes ciphers on CCS

The TLS (pre-1.3) ChangeCipherState message is usually used to indicate
the switch from the unencrypted to encrypted part of the handshake.
However, it can also be used in cases where there is an existing
session (such as during resumption handshakes) or when changing from
one cipher to a different one (such as during renegotiation when the
cipher list offered by the client has changed).  This test serves
to exercise such situations, allowing us to detect whether session
objects are being modified in cases when they must remain immutable
for thread-safety purposes.

Code to thread-safety in ChangeCipherState

The server-side ChangeCipherState processing stores the new cipher
in the SSL_SESSION object, so that the new state can be used if
this session gets resumed.  However, writing to the session is only
thread-safe for initial handshakes, as at other times the session
object may be in a shared cache and in use by another thread at the
same time.  Reflect this invariant in the code by only writing to
s->session->cipher when it is currently NULL (we do not cache sessions
with no cipher).  The code prior to this change would never actually
change the (non-NULL) cipher value in a session object, since our
server enforces that (pre-TLS-1.3) resumptions use the exact same
cipher as the initial connection, and non-abbreviated renegotiations
have produced a new session object before we get to this point.
Regardless, include logic to detect such a condition and abort the
handshake if it occurs, to avoid any risk of inadvertently using
the wrong cipher on a connection.

Don't write to the session when computing TLS 1.3 keys

TLS 1.3 maintains a separate keys chedule in the SSL object, but
was writing to the 'master_key_length' field in the SSL_SESSION
when generating the per-SSL master_secret.  (The generate_master_secret
SSL3_ENC_METHOD function needs an output variable for the master secret
length, but the TLS 1.3 implementation just uses the output size of
the handshake hash function to get the lengths, so the only natural-looking
thing to use as the output length was the field in the session.
This would potentially involve writing to a SSL_SESSION object that was
in the cache (i.e., resumed) and shared with other threads, though.

The thread-safety impact should be minimal, since TLS 1.3 requires the
hash from the original handshake to be associated with the resumption
PSK and used for the subsequent connection.  This means that (in the
resumption case) the value being written would be the same value that was
previously there, so the only risk would be on architectures that can
produce torn writes/reads for aligned size_t values.

Since the value is essentially ignored anyway, just provide the
address of a local dummy variable to generate_master_secret() instead.
