Emergency Numbers can only be digits, so there's no point to use the
'Hammer of Thor' that is g_utf8_validate when a much simpler function
will do the job just as well.
XLEMA reports emergency numbers that are hardcoded (e.g. 112 and 911)
and that are already read from EFecc. The additional emergency numbers
we are interested in should only come from the NVM or the network NITZ
update.
This might be either a modem firmware bug or the SIM card is provisioned
really badly, but the last entry contains garbage characters.

Fix this by just validating the string and cutting off once an invalid
character is found.

This enables the Infineon specific emergency call state notifications so
that they show up in the traces when this happens. No logic to handle
them properly is implemented.
This patch adds support for setting up a GPRS context and then switching
it into M-RAW_IP mode. The handling of the M-RAW_IP data stream is not
yet implemented.
The Infineon modem returns more detailed information of the SIM Toolkit
proactive sessions to the modem driver. A proactive session starts with
the status response '91 xx' (proactive command pending) and ends with a
status response response of '90 00' (normal ending of command) after
Terminal Response.
So only when receiving '90 00' result, the indication that the session
has ended should be given to the core.
The current Infineon firmware overloads the AT+CFUN command with
enabling SIM Toolkit and fetching of proactive commands. It seems
to be safe to send this command in offline mode (AT+CFUN=4) and
also in online mode (AT+CFUN=1). These are the two cases where
SIM Toolkit atom would be initialized.
