The core libwayland libraries should not handle logging, only passing
the error messages to subscribed functions.
An application linked to libwayland-server or libwayland-client
will be able to set own functions (one per library) to handle error
messages.
Change in this series: make the wl_log return int, because
of compatibility with printf. It will return the number of bytes logged.
Set the next and prev pointers of the removed list element to NULL. This
will catch programming errors that would use invalid list pointers,
double-remove for instance.
It also helps debugging, making it easy to see in gdb if an object is
not in a list.

We set aside a range of the object ID space for use by the server. This
allows the server to bind an object to an ID for a client and pass that
object to the client. The client can use the object immediately and the
server can emit events to the object immdiately.
