ruih: Make ServiceManager a singleton

Service was keeping information that belonged to ServiceManager and
basically constructing it in its static constructor to create a single
instance that was watching the file.

This commit moves all static members of Service to ServiceManager,
making it a full GObject and using the general singleton pattern we use
in Rygel.

This also fixes an potential issue in multi-homed hosts that the
static file-monitor would cancelled by Service's instance destructor if
one network interface went down.

ruih: Allow null for protocols

The code checks for == null and returns true then. But if the variable
is not marked as nullable, vala will add g_val_return_if_fail (FALSE,…
to the beginning of the function.

ruih: Remove unreachable code

IconElem is created while iterating a list and icon_node->name is checked
before creating the element. It's impossible to pass a null-node here.
