I want to know all the classes and functions(individual .php files) in a wordpress installation that handle serialization and unserialization.

WordPress uses
maybe_serialize()andmaybe_unserialize(). Both of them use PHP’s nativeserialize()andunserialize()functions. See:http://phpxref.ftwr.co.uk/wordpress/wp-includes/functions.php.source.html#l1028
http://phpxref.ftwr.co.uk/wordpress/wp-includes/functions.php.source.html#l222
Both of those functions make use of the function
is_serialized(), which checks if the variable is serialized yet. See:http://phpxref.ftwr.co.uk/wordpress/wp-includes/functions.php.source.html#l222
