[vala-extra-vapis] Improvments for memcached.vapi binding.

[Evan Nemerson <evann src gnome org>]

commit 7828e70c96a58f6ac318b8a25aab33101fa4df96

    Improvments for memcached.vapi binding.
    
    Binds memcached_create as the default constructor and rename the old
    constructor for Context.from_configuration.
    
    Binds clone and pass the instance as second argument.
    
    Marks servers_parse deprecated as Context.from_configuration should be
    used instead.
    
    Provides an iterator to call fetch_result in a foreach loop.
