The Share Button is still alive and kicking, what Facebook did remove support for though was the old Javascript SDK, identified by the connect.php or FeatureLoader.js.php endpoints.

If you absolutely do not want to switch to the officially supported Like Button (which has the same features), then you can easily get the Share Button back by following https://developers.facebook.com/docs/plugins/ and using the <fb:share-button> or <div class=”fb-share-button> tags.
