[librest] Add rest_proxy_call_get_function()

[Christophe Fergeau <teuf src gnome org>]

commit 3513c3d80c4b5f60ab6531e5514a538f3e93f85e

    Add rest_proxy_call_get_function()
    
    There are rest_proxy_call_[gs]et_method() methods, a
    rest_proxy_call_set_function() method, but no corresponding getter.
    Adding it makes the API more consistent.
