Unit tests were failing to build because random header was included by
kernel_includes.h. The problem is that rand32.h includes a generated
file that is either not generated or not included when building unit
tests. Also, it is better to limit the scope of this file to where it is
used.

The implementation of offload_getaddrinfo in this driver failed
when the node it was called with was an IP address. This condition
was never detected, and as a consequence a DNS query was done on
the IP address instead of returning it directly.
Also, the port was set first after running the DNS query.
As a consequence, if the IP address would have been returned directly,
this would have been done without a port been set.
Both errors are fixed in this patch.

During communication initialisation, the IMSI of the inserted SIM
card is evaluated to determine the APN. This is done by comparing
the first 5 characters of the IMSI to a list of known providers.
The list can be given in Kconfig.
To enable this functionality, set following bool in Kconfig:
MODEM_UBLOX_SARA_AUTODETECT_APN
To set a list of providers, set following string:
MODEM_UBLOX_SARA_AUTODETECT_APN_PROFILES
If the provider can not be found in the list, the APN given in
following entry is used as a fallback:
MODEM_UBLOX_SARA_R4_APN

Following issue is addressed in this bugfix:
When using offloaded sockets with modem ublox_sara_r4,
the socket is only closed if it is in connected state
at the time of the function call. When using UDP sockets,
this leads to a socket never being closed.

Calculation of RSSI was done incorrectly for Sara U201.
When evaluating +CSQ command responses, the RSSI can be calculated
from the first value, which is <signal_strength>. Instead, the
RSSI was calculated from the second value, which is <qual>.
With the subsequent mapping to RSSI, this results in a wrong
value for RSSI.
This is now corrected by using value <signal_strength> to calculate
the RSSI.
Tested using Sara U201.

This commit references modem_pin() and modem_shell()
modem_pin(): use new gpio api
The existing pin driver does not respect gpio
configuration in device tree for active high / low
This commit allows for the device tree to determine the
active logic level.
modem_shell(): use correct string length
The ms_send macro uses iface.write() to send a string.
iface.write() requires the length of the string not the
size of the string.
This commit corrects the string length.

Some commands need to be processed before a "\r\n" is available and
there might also be commands that have "\r\n" as data but doesn't mean
the end of the command.
To solve this a MODEM_CMD_DIRECT has been added. cmd_handler_process()
will look for matching direct commands before checking if a whole line
is available for matching the normal commands.
A direct command can return either -EAGAIN, meaning that more data is
needed or it will return the number of bytes to skip forward, ie the
length of the command that was handled.

For AT+UPSD=0, 1, "<value>": we are setting value to MCCMNO, which

Misc fixes / enhancements to the GSM driver:

not infinite

Instead of using global static variable "gsm" everywhere,
store the context when calling DEVICE_INIT(). Then in the device
init function get the context from the device struct. This way
it is possible to use the same functions for implementing two
gsm modem instances. Currently this is not fully possible because
the context is not passed via uart_pipe API and modem_cmd
callbacks. So some future work would still be needed.
In practice this commit does not change anything, it just makes
it a little bit easier to have two instance of this modem which
might be quite unlikely case. Anyway, the driver now follows the
same style how some other drivers are done like Ethernet etc.
