    Fixes bug 949038

    Make the api calls better fit the standard pattern where
    read_deleted can be changed using context.read_deleted

    I have retained the ability to pass read_deleted
    explicitly. If that is not specified, it uses the value in
    the context.

    Note: read_deleted defaults to "no" in the context.

    The two exceptions are:
     aggregate_host_get_all
     aggregate_get_all

    In this case, it is better for read_deleted=yes to be the default
    So in this case the context cannot be used, as that would default
    to read_deleted=no. In this case you must explicity override
    read_deleted, the context is totally ignored, as before.
