At gprs atom 'probe' state, max cid query may fail due to rild
status isn't RADIO_STATUS_ON. It causes gprs atom is removed, gprs
feature is inavailable. Move gprs atom creating to 'post_online'
state to make sure rild status is RADIO_STATUS_ON when query max
cid.
addrs variable seems to be used whenever multiple addresses are being
references. Either as a strv or a compound string separated by a
separator. In these cases addrs was used for a single address, which
was confusing.
After input PIN wrong 3 times, sim main state (include spn_watches)
is freed. but the watch id still be kept by other atoms (network and
gprs), when remove the atom, it will try to remove the watch from
spn_watches, ofono daemon will crash.
rs->imsi is only freed when rs->settings is true. So tweak the logic
inside radio_load_settings to only strdup the imsi when settings
creation has succeeded.
In some cases it is possible that a context is opened after a detach
event has been received, and right before an attach, depending on the
modem. We make sure that those contexts are removed to keep
consistency.
Some phones with an active and waiting call at the time of HFP SLC
establishment, may send call waiting notification before all calls
are synchronized. This will lead to call Id mismatch because call
object is created with assumed Id 1 and not Id assigned by the phone.
In example below waiting call is created with Id 1 but in AT+CLCC
this phone returns active call as call with Id 1, and waiting as 2.
