All command line options now have long names
as they are required by GLib.
So the supported command line options now are:
-h, --help
-d, --debug
-s, --virtio-serial-port-path
-S, --vdagentd-socket
-u, --uinput-device
-f, --fake-uinput
-x, --foreground
-o, --one-session
-X, --disable-session-integration
Change the types of some global variables that hold the options:
- const char * --> gchar *
- int --> gboolean
Define DEFAULT_UINPUT_DEVICE as "/dev/uinput",
since there's already DEFAULT_VIRTIO_PORT_PATH, VDAGENTD_SOCKET.
