rand_pool_bytes_needed() was constructed in such a way that the
smallest acceptable entropy factor was 1 entropy bits per 8 bits of
data. At the same time, we have a DRBG_MINMAX_FACTOR that allows
weaker source, as small as 1 bit of entropy per 128 bits of data.
The conclusion is that rand_pool_bytes_needed() needs to change to
support weaker entropy sources. We therefore change the input of
entropy per byte to be an entropy factor instead. This entropy factor
expresses how many bits of data it takes (on average) to get 1 bit of
entropy.

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.

Fixes#5849
In pull request #5503 a fallback was added which adds a random nonce of
security_strength/2 bits if no nonce callback is provided. This change raised
the entropy requirements form 256 to 384 bit, which can cause problems on some
platforms (e.g. VMS, see issue #5849).
The requirements for the nonce are given in section 8.6.7 of NIST SP 800-90Ar1:
A nonce may be required in the construction of a seed during instantiation
in order to provide a security cushion to block certain attacks.
The nonce shall be either:
a) A value with at least (security_strength/2) bits of entropy, or
b) A value that is expected to repeat no more often than a
(security_strength/2)-bit random string would be expected to repeat.
Each nonce shall be unique to the cryptographic module in which instantiation
is performed, but need not be secret. When used, the nonce shall be considered
to be a critical security parameter.
This commit implements a nonce of type b) in order to lower the entropy
requirements during instantiation back to 256 bits.
The formulation "shall be unique to the cryptographic module" above implies
that the nonce needs to be unique among (with high probability) among all
DRBG instances in "space" and "time". We try to achieve this goal by creating a
nonce of the following form
nonce = app-specific-data || high-resolution-utc-timestamp || counter
Where || denotes concatenation. The application specific data can be something
like the process or group id of the application. A utc timestamp is used because
it increases monotonically, provided the system time is synchronized. This approach
may not be perfect yet for a FIPS evaluation, but it should be good enough for the
moment.
This commit also harmonizes the implementation of the get_nonce() and the
get_additional_data() callbacks and moves the platform specific parts from
rand_lib.c into rand_unix.c, rand_win.c, and rand_vms.c.

Historically we used to implement standalone base64 code for SRP. This
was replaced by commit 3d3f21aa with the standard base64 processing code.
However, the SRP base64 code was designed to be compatible with other SRP
libraries (notably libsrp, but also others) that use a variant of standard
base64. Specifically a different alphabet is used and no padding '='
characters are used. Instead 0 padding is added to the front of the string.
By changing to standard base64 we change the behaviour of the API which may
impact interoperability. It also means that SRP verifier files created prior
to 1.1.1 would not be readable in 1.1.1 and vice versa.
Instead we expand our standard base64 processing with the capability to be
able to read and generate the SRP base64 variant.

There are two undocumented DSA parameter generation options available in
the genpkey command line app:
dsa_paramgen_md and dsa_paramgen_q_bits.
These can also be accessed via the EVP API but only by using
EVP_PKEY_CTX_ctrl() or EVP_PKEY_CTX_ctrl_str() directly. There are no
helper macros for these options.
dsa_paramgen_q_bits sets the length of q in bits (default 160 bits).
dsa_paramgen_md sets the digest that is used during the parameter
generation (default SHA1). In particular the output length of the digest
used must be equal to or greater than the number of bits in q because of
this code:
if (!EVP_Digest(seed, qsize, md, NULL, evpmd, NULL))
goto err;
if (!EVP_Digest(buf, qsize, buf2, NULL, evpmd, NULL))
goto err;
for (i = 0; i < qsize; i++)
md[i] ^= buf2[i];
/* step 3 */
md[0] |= 0x80;
md[qsize - 1] |= 0x01;
if (!BN_bin2bn(md, qsize, q))
goto err;
qsize here is the number of bits in q and evpmd is the digest set via
dsa_paramgen_md. md and buf2 are buffers of length SHA256_DIGEST_LENGTH.
buf2 has been filled with qsize bits of random seed data, and md is
uninitialised.
If the output size of evpmd is less than qsize then the line "md[i] ^=
buf2[i]" will be xoring an uninitialised value and the random seed data
together to form the least significant bits of q (and not using the
output of the digest at all for those bits) - which is probably not what
was intended. The same seed is then used as an input to generating p. If
the uninitialised data is actually all zeros (as seems quite likely)
then the least significant bits of q will exactly match the least
significant bits of the seed.
This problem only occurs if you use these undocumented and difficult to
find options and you set the size of q to be greater than the message
digest output size. This is for parameter generation only not key
generation. This scenario is considered highly unlikely and
therefore the security risk of this is considered negligible.

The GOST engine needs to be loaded before we initialise libssl. Otherwise
the GOST ciphersuites are not enabled. However the SSL conf module must
be loaded before we initialise libcrypto. Otherwise we will fail to read
the SSL config from a config file properly.
Another problem is that an application may make use of both libcrypto and
libssl. If it performs libcrypto stuff first and OPENSSL_init_crypto()
is called and loads a config file it will fail if that config file has
any libssl stuff in it.
This commit separates out the loading of the SSL conf module from the
interpretation of its contents. The loading piece doesn't know anything
about SSL so this can be moved to libcrypto. The interpretation of what it
means remains in libssl. This means we can load the SSL conf data before
libssl is there and interpret it when it later becomes available.

When these two functions returned zero, it could mean:
1. that an error occured. In their case, the error is an overflow of
the pool, i.e. the correct response from the caller would be to
stop trying to fill the pool.
2. that there isn't enought entropy acquired yet, i.e. the correct
response from the caller would be to try and add more entropy to
the pool.
Because of this ambiguity, the returned zero turns out to be useless.
This change makes the returned value more consistent. 1 means the
addition of new entropy was successful, 0 means it wasn't. To know if
the pool has been filled enough, the caller will have to call some
other function, such as rand_pool_entropy_available().

Where a CMS detached signature is used with text content the text goes
through a canonicalisation process first prior to signing or verifying a
signature. This process strips trailing space at the end of lines, converts
line terminators to CRLF and removes additional trailing line terminators
at the end of a file. A bug in the canonicalisation process meant that
some characters, such as form-feed, were incorrectly treated as whitespace
and removed. This is contrary to the specification (RFC5485). This fix
could mean that detached text data signed with an earlier version of
OpenSSL 1.1.0 may fail to verify using the fixed version, or text data

Current endianness detection is somewhat opportunistic and can fail
in cross-compile scenario. Since we are more likely to cross-compile
for little-endian now, adjust the default accordingly.

There is a requirements of having access to a live entropy source
which we can't do with the default callbacks. If you need prediction
resistance you need to set up your own callbacks that follow the
requirements of NIST SP 800-90C.

Fixes#4403
This commit moves the internal header file "internal/rand.h" to
<openssl/rand_drbg.h>, making the RAND_DRBG API public.
The RAND_POOL API remains private, its function prototypes were
moved to "internal/rand_int.h" and converted to lowercase.
Documentation for the new API is work in progress on GitHub #5461.

Not all algorithms will support this, since their keys are not a simple
block of data. But many can.

With the current mechanism, old cipher strings that used to work in 1.1.0,
may inadvertently disable all TLSv1.3 ciphersuites causing connections to
fail. This is confusing for users.
In reality TLSv1.3 are quite different to older ciphers. They are much
simpler and there are only a small number of them so, arguably, they don't
need the same level of control that the older ciphers have.
This change splits the configuration of TLSv1.3 ciphers from older ones.
By default the TLSv1.3 ciphers are on, so you cannot inadvertently disable
them through your existing config.

Unlike "upstream", Android NDK's arm64 gcc [but not clang] performs
64x64=128-bit multiplications with library calls, which appears to
have devastating impact on performance. [The condition is reduced to
__ANDROID__ [&& !__clang__], because x86_64 has corresponding
assembly module.]
