Use AT#QSS=2 instead of AT#QSS=1 to get an URC when the SIM is not only
inserted but also when PIN is unlocked and when SMS + phonebook are

Disable sim state notification in telit_enable() so that we sure get a
notification when we enable it later again. This way we don't have to
query the state the first time. Without this the Telit modem does not
always send an URC when AT#QSS=2 is sent.
Remove sim_inserted_source and sim_inserted_timeout_cb which are not
needed anymore as a consequence.
By the way the 1 second timeout was an ugly hack.
Don't query current SIM status in cfun_enable_cb() as the SIM is
disabled due to prior AT+CFUN=4.
Register '#QSS:' before enabling sim state notifications.
Remove telit_qss_cb() which was used as a callback for querying the
current SIM status.

Patch looks good to me overall, however:
cc1: warnings being treated as errors
plugins/telit.c: In function ‘switch_sim_state_status’:
plugins/telit.c:226:4: error: statement with no effect
plugins/telit.c:240:4: error: statement with no effect
plugins/telit.c: At top level:
plugins/telit.c:64:20: error: ‘qss_prefix’ defined but not used
Sorry, it is getting embarrassing now.
Also, one other thing I'm concerned about is the CFUN=4 usage when we
try to set the modem offline. Your comments indicate that the Telit
modem resets the SIM when we issue CFUN=4. Going from Online True ->
False we don't actually want to reset the SIM. Does CFUN take an extra
parameter to turn SIM reset off by any chance?
Telit documentation says that +CFUN supports a second parameter which
should turn reset off.
AT+CFUN=? also returns +CFUN: (0,1,2,4,5),(0)
AT reference manual: "reset flag 0 - do not reset the ME before
setting it to <fun> functionality level"
But the modem keeps returning +CME ERROR: 4 when I try it (no matter
which CFUN level).
The modem behaves very strange sometimes. I kept getting timeouts when
setting AT+CFUN=4. I once tried it manually and it took 26 seconds until
I got an OK.
Currently it works fine again.
Regards,
Christopher
