Move SSL_CIPHER section just above cipher suite configuration.

Browse Source 
Putting it at the top was probably a mistake? Even though SSL_CIPHER
(like SSL_SESSION) doesn't depend on SSL, if you're reading through the
header, SSL_CTX and SSL are the most important types. You could even use
the library without touch cipher suite configs if you don't care since
the default is decently reasonable, though it does include a lot of
ciphers. (Hard to change that if we wanted to because DEFAULT is often
used somewhat like ALL and then people subtract from it.)
