Remove PIN/PUK keyguard when SIM is removed/ready

1) If the PIN/PUK keyguard comes up for a locked
SIM, it can not be removed by removing the
affected SIM. It can only be removed by
rebooting the device or entering a bogus PIN.

This change automatically clears the keyguard
when when the locked SIM is removed. It will
be shown again if the locked SIM is re-entered.

2) If the device is PUK locked and the code
**05*PUK*new pin* new Pin# is entered in the
emergency dialer, it will unlock the SIM.
By listening to the READY state, we can remove
the keyguard when the SIM is unlocked by
other means.
