Provide a SSL_CIPHER_get_by_value() function that allows a cipher to be
retrieved via its cipher suite value. A corresponding SSL_CIPHER_by_value()
function returns the cipher suite value for a given SSL_CIPHER. These
functions should mean that software does not need to resort to
put_cipher_by_char()/get_cipher_by_char() in order to locate a cipher.
Begrudgingly also provide a SSL_CIPHER_get_by_id() function that locates a
cipher via the internal cipher identifier. Unfortunately these have already
been leaked outside the library via SSL_CIPHER_by_id() and the various
SSL3_CK_* and TLS1_CK_* defines in the ssl3.h/tls1.h headers.
