[ruby/openssl] ossl.c: implement OpenSSL::OpenSSLError#detailed_message

An OpenSSL function sometimes puts more than one error entry into the
thread-local OpenSSL error queue. Currently, we use the highest-level
entry for generating the exception message and discard the rest.

Let ossl_make_error() capture all current OpenSSL error queue contents
into OpenSSL::OpenSSLError#errors and extend
OpenSSL::OpenSSLError#detailed_message to include the information.

An example:

    $ ruby -Ilib -ropenssl -e'OpenSSL::X509::ExtensionFactory.new.create_ext("a", "b")'
    -e:1:in 'OpenSSL::X509::ExtensionFactory#create_ext': a = b: error in extension (name=a, value=b) (OpenSSL::X509::ExtensionError)
    OpenSSL error queue reported 2 errors:
    error:11000082:X509 V3 routines:do_ext_nconf:unknown extension name
    error:11000080:X509 V3 routines:X509V3_EXT_nconf_int:error in extension (name=a, value=b)
            from -e:1:in '<main>'
