    libs/guest: don't use unsigned long as type for PFNs
    
    Declarations of xc_dom_console_init() and
    xc_dom_console_set_disconnected() in libxenguest.h don't match their
    implementation in the library.
    
    Under arm32, xen_pfn_t is a uint64_t and wider than unsigned long.
    
    Use xen_pfn_t for GFNs in the library to fix that. At the same time
    change the parameter name of the implementation to console_gfn,
    matching the interface declaration in the header and reality (it is
    a GFN, not a PFN).
    
    Fixes: b6fc307b0b00 ("libs/guest: Set console as disconnected on resume")
    Fixes: 971b7d5ecbcd ("libs/guest: Set console page to disconnected")
