Test that the error message contains the necessary text instead of the
exact match. Exceptions raised by ossl_raise() may carry additional
context information in the message.

[ This is a backport to the 2.1 branch. ]

Fixed misspellings reported at [Bug #16437], for default gems.

(cherry picked from commit ruby/ruby@e68999c82c4863d33a6f893661fba1b7538c5671)

The .include directive was initially added by OpenSSL 1.1.1, but the
syntax was later modified in 1.1.1b to improve compatibility with the
parser in <= 1.1.0. The test case expects 1.1.1b's parser.

The test case is failing on Ubuntu 18.04 because it still uses the
initial 1.1.1 release:

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.

LibreSSL has removed the feature to map environment variables onto the
"ENV" section.

https://github.com/ruby/openssl/commit/b70817faec

Sort keys of a section before comparing. The ordering is not part of the
API. This can cause a test failure if we use OpenSSL's C implementation.

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#[]=
