Although the manpage says that BIGNUM functions return 0 on error,
OpenSSL versions before 1.0.2n and current LibreSSL versions may return
-1 instead.
Note that the implementation of OpenSSL::BN#mod_inverse is extracted
from BIGNUM_2c() macro as it didn't really share the same function
signature with others.

This defines TLS1_3_VERSION when using LibreSSL 3.2+. LibreSSL 3.2/3.3
doesn't advertise this by default, even though it will use TLS 1.3
in both client and server modes.
Changes between LibreSSL 3.1 and 3.2/3.3 broke a few tests, Defining
TLS1_3_VERSION by itself fixes 1 test failure. A few tests now
fail on LibreSSL 3.2/3.3 unless TLS 1.2 is set as the maximum version,
and this adjusts those tests. The client CA test doesn't work in
LibreSSL 3.2+, so I've marked that as pending.
For the hostname verification, LibreSSL 3.2.2+ has a new stricter
hostname verifier that doesn't like subjectAltName such as
c*.example.com and d.*.example.com, so adjust the related tests.
With these changes, the tests pass on LibreSSL 3.2/3.3.

The form created an empty EC_GROUP object with the specified EC_METHOD.
However, the feature was unfinished and not useful in any way because
OpenSSL::PKey::EC::Group did not implement wrappers for necessary
functions to set actual parameters for the group, namely
EC_GROUP_set_curve() family.
EC_GROUP object creation with EC_METHOD explicitly specified is
deprecated in OpenSSL 3.0, as it was apparently not intended for use
outside OpenSSL.
It is still possible to create EC_GROUP, but without EC_METHOD
explicitly specified - OpenSSL chooses the appropriate EC_METHOD for
the curve type. The OpenSSL::PKey::EC::Group.new(<:GFp|:GF2m>, p, a, b)
form will continue to work.

The underlying API SSL_CTX_set_tmp_ecdh_callback() was removed by
LibreSSL >= 2.6.1 and OpenSSL >= 1.1.0, in other words, it is not
supported by any non-EOL versions of OpenSSL.
The wrapper was initially implemented in Ruby 2.3 and has been
deprecated since Ruby/OpenSSL 2.0 (bundled with Ruby 2.4) with explicit
warning with rb_warn().

Undo special treatment of nil and simply pass the value to
StringValueCStr().
nil was never a valid argument for the method; OpenSSL::X509::StoreError
with an unhelpful error message "system lib" was raised in that case.
https://github.com/ruby/openssl/commit/fb2fcbb137
SSLContext's verify_mode expects an SSL_VERIFY_* constant (an integer)
and verify_hostname expects either true or false. However, they are set
to nil after calling OpenSSL::SSL::SSLContext.new, which is surprising.
Set a proper value to them by default: verify_mode is set to
OpenSSL::SSL::VERIFY_NONE and verify_hostname is set to false by
default.
Note that this does not change the default behavior. The certificate
verification was never performed unless verify_mode is set to
OpenSSL::SSL::VERIFY_PEER by a user. The same applies to
verify_hostname.

Explicitly check for type given some conflicting statements within openssl's
documentation around EVP_PKEY_cmp and EVP_PKEY_ASN1_METHOD(3).
Add documentation with an example for compare?
https://github.com/ruby/openssl/commit/0bf51da6e2
Use the EVP API instead of the low-level HMAC API. Use of the HMAC API
has been discouraged and is being marked as deprecated starting from
OpenSSL 3.0.0.
The two singleton methods OpenSSL::HMAC, HMAC.digest and HMAC.hexdigest
are now in lib/openssl/hmac.rb.
https://github.com/ruby/openssl/commit/0317e2fc02
Deprecate it for future removal. However, I do not expect any
application is affected by this.
The other form of calling it, PKey::EC::Point#mul(bn [, bn]) remains
untouched.
PKey::EC::Point#mul calls EC_POINTs_mul(3) when multiple BNs
are given as an array. LibreSSL 2.8.0 released on 2018-08 removed the
feature and OpenSSL 3.0 which is planned to be released in 2020 will
also deprecate the function as there is no real use-case.
https://github.com/ruby/openssl/commit/812de4253d
Add OpenSSL::PKey::PKey#derive as the wrapper for EVP_PKEY_CTX_derive().
This is useful for pkey types that we don't have dedicated classes, such
as X25519.
https://github.com/ruby/openssl/commit/28f0059bea
OpenSSL 1.1.1 added EVP_DigestSign() and EVP_DigestVerify() functions
to the interface. Some EVP_PKEY methods such as PureEdDSA algorithms
do not support the streaming mechanism and require us to use them.
https://github.com/ruby/openssl/commit/ae19454592
Use EVP_DigestSign*() and EVP_DigestVerify*() interface instead of the
old EVP_Sign*() and EVP_Verify*() functions. They were added in OpenSSL
1.0.0.
Also, allow the digest to be specified as nil, as certain EVP_PKEY types
don't expect a digest algorithm.
https://github.com/ruby/openssl/commit/9ff6e5143b
The EVP interface cannot tell whether if a pkey contains the private
components or not. Assume it does if it does not respond to #private?.
This fixes the NoMethodError on calling #sign on a generic PKey.

Merge the code into the callers so that the wrapping Ruby object is
allocated before the raw key object is allocated. This prevents possible
memory leak on Ruby object allocation failure, and also reduces the
lines of code.

Now that OpenSSL::Config wraps a real CONF object, the caller can just
borrow it rather than creating a new temporary CONF object. CONF object
is usually treated as immutable.
DupConfigPtr() is now removed, and GetConfig() is exported instead.
https://github.com/ruby/openssl/commit/d9064190ca
Revert OpenSSL::Config to using the OpenSSL API and remove our own
parser implementation for the config file syntax.
OpenSSL::Config now wraps a CONF object. Accessor methods deal with the
object directly rather than Ruby-level internal state.
This work is based on the old C code we used before 2010.

Remove 4 deprecated methods.
The following two methods have been marked as deprecated since 2003,
by r4531 (ruby.git commit 78ff3833fb67c8005a9b851037e74b3eea940aa3).
- OpenSSL::Config#value
- OpenSSL::Config#section
Other two methods are removed because the corresponding functions
disappeared in OpenSSL 1.1.0.
- OpenSSL::Config#add_value
- OpenSSL::Config#[]=

Allow specifying just length to #update
CCM mode ciphers need to specify the total plaintext or ciphertext
length to EVP_CipherUpdate.
Update the link to the tests file
Define Cipher#ccm_data_len= for CCM mode ciphers
Add a unit test for CCM mode
Also check CCM is authenticated when testing
https://github.com/ruby/openssl/commit/bb3816953b
This lets us cast a Fiddle::Function to a block, allowing is to write
things like:
```ruby
f = Fiddle::Function.new(@libc['strcpy'], [TYPE_VOIDP, TYPE_VOIDP], TYPE_VOIDP)
define_method :strcpy, &f
```
