* Obsoleted all SaslMechanism constructors that took a Uri argument and replaced them with variants that no longer require the Uri and instead take a NetworkCredential or a set of strings for the user name and password.

Note to users upgrading from MailKit 1.x:

In order to authenticate using the XOAUTH2 SASL mechanism, you must now use the following approach:

client.Authenticate (new SaslMechanismOAuth2 (username, auth_token));
