Issue #14837: SSL errors now have library and reason attributes describing precisely what happened and in which OpenSSL submodule.

Browse source 
The str() of a SSLError is also enhanced accordingly.

NOTE: this commit creates a reference leak.  The leak seems tied to the
use of PyType_FromSpec() to create the SSLError type.  The leak is on the
type object when it is instantiated:

>>> e = ssl.SSLError()
>>> sys.getrefcount(ssl.SSLError)
35
>>> e = ssl.SSLError()
>>> sys.getrefcount(ssl.SSLError)
36
>>> e = ssl.SSLError()
>>> sys.getrefcount(ssl.SSLError)
37
