Teach git about a new option, "http.sslCipherList", which permits one to
specify a list of ciphers to use when negotiating SSL connections. The
setting can be overwridden by the GIT_SSL_CIPHER_LIST environment
variable.

+http.sslCipherList::
+ A list of SSL ciphers to use when negotiating an SSL connection.
+ The available ciphers depend on whether libcurl was built against
+ NSS or OpenSSL and the particular configuration of the crypto

+Can be overridden by the 'GIT_SSL_CIPHER_LIST' environment variable.
+To force git to use libcurl's default cipher list and ignore any

+empty string.

http.sslVerify::
Whether to verify the SSL certificate when fetching or pushing
over HTTPS. Can be overridden by the 'GIT_SSL_NO_VERIFY' environment
