Libosso API: osso_state_write failed

[yanglei]

the osso_state_write return OSSO_ERROR:
-----------------------------------------------------------------------------
static char* s = "this is the state";
    guint32 len = strlen(s)+1;
    osso_context = osso_initialize("osso_init", "0.0.1", TRUE, NULL);

    if (osso_context == NULL) {
        return OSSO_ERROR;
    }

    state.state_size = len;
    state.state_data = (gpointer)s;
    result = osso_state_write(osso_context, &state);
    if(result != OSSO_OK) {
        if(result == OSSO_ERROR)
                g_print("ERROR: osso_state_write return OSSO_ERROR\n");
        else if(result == OSSO_INVALID)
                g_print("ERROR: osso_state_write return OSSO_INVALID\n");
        else
                g_print("ERROR: osso_state_write return UNKNOWN\n");
        return -1;
    }

This bug is same as the bug Todd reported #145951
He describe the root cause:
--------------------------------------------------------------------------------------------
The problem is that libosso expects the env var STATESAVEDIR
to exist and point to a valid directory where state data
for the resident application can be saved/restored. This var
is not set by the hildon-control-panel install or by the
controlpanel process. Without it libosso defaults to
/tmp/state/controlpanel/0.1 and since this dir usually won't
exist without someone manually creating it, the error occurs.

The solution is to have the conrtolpanel process create this
variable and directory on startup.
---------------------------------------------------------------------------------------------
From Control Panel's perspective, I think it is OK to close the bug #145951.
But for API osso_state_write and osso_state_read, returning OSSO_ERROR is existed yet.
Keep tracking the APIs use in this bug.

This is low impact to the customer and might be fixed in later versions of Hildon.
