When sleep modes are used, sockets are restored from NV after boot.
If the network changes IP addresses, restore sockets maintain old network
info in the HL7800 firmware.
On boot, restored sockets should be closed to ensure new sockets
are created with updated network info.

`+C*REG:` may be received as AT read command answer
or unsolicited notification.
Their syntax differs, and even the overall parameter count varies
depending on what `<n>` is used in the `AT+CEREG=` write command.
To handle all cases properly, check the parameter count and
the presence of the `<tac>` parameter (which is a string and
thus begins with `"`) to figure out what is the position of `<stat>`.

CONFIG_ZVFS_POLL_MAX is now used to control the maximum number of poll()

be deprecated.
Modify the defaults for NET_SOCKETS_POLL_MAX and ZVS_POLL_MAX so that
the deprecation actually makes sense instead of symbol removal. In case
the application still sets the old config, it will modify the

Introduced `MODEM_CELLULAR_DEFINE_INSTANCE` macro to streamline
the definition and initialization of modem cellular instances.
This macro enables passing parameters that vary among modems, including:
`power_pulse_duration_ms`, `reset_pulse_duration_ms`, `startup_time_ms`,
`shutdown_time_ms`, `autostarts`, `init_chat_script`, `dial_chat_script`
and `periodic_chat_script`.
This will reduce the number of redundant lines in the code, aiming for

For each of the fdtable.h functions listed below, convert the
z_ prefixed semi-private functions to use the zvfs_ prefix.
ZVFS stands for Zephyr Virtual File System and
is intended to be a common library used by the C library,
POSIX API, Networking, Filesystem, and other areas.
There are already a few functions in fdtable.h that use the
zvfs_ prefix, so this change is mostly about unifying them in
a way that uses a suitable prefix ("namespace") so that it can
be considered a public API.
- z_alloc_fd
- z_fdtable_call_ioctl
- z_finalize_fd
- z_finalize_typed_fd
- z_free_fd
- z_get_fd_obj
- z_get_fd_obj_and_vtable
- z_get_obj_lock_and_cond

The supported modems don't have the same number or assignment
of DLCI channels. For example, the NRF91_SLM only has DLCI
channel 3 assigned to GNSS tunneling, where the ublox sara r5
has DLCI 3 assigned to an additional AT channel, and DLCI 4
assigned to GNSS tunneling.
This commit updates the creation and assignment of DLCI
channels and pipelinks to match the capabilties of each modem.

Add AT shell which uses the newly exposed pipes to
send/receive at commands from the modem identified by the
chosen node zephyr,at-shell.
To send an AT command, the shell command at is used, followed
by the command to send, and an optional response which
overwrites the default "OK"
For example, sending "AT", which returns "OK"
modem at at <- command
OK <- response
Enabling echo, then sending "AT" which will now return "AT" + "OK"
modem at ati1 <- command
OK <- response
at at <- command
at <- response
OK <- response

The POSIX_MAX_FDS option does not correspond to any standard
POSIX option. It was used to define the size of the file
descriptor table, which is by no means exclusively used by
POSIX (also net, fs, ...).
POSIX_MAX_FDS is being deprecated in order to ensure that
Zephyr's POSIX Kconfig variables correspond to those defined in
the specification, as of IEEE 1003.1-2017. Namely,
POSIX_OPEN_MAX. CONFIG_POSIX_MAX_OPEN_FILES is being deprecated
for the same reason.
To mitigate any possible layering violations, that option is
not user selectable. It tracks the newly added
CONFIG_ZVFS_OPEN_MAX option, which is native to Zephyr.
With this deprecation, we introduce the following Kconfig
options that map directly to standard POSIX Option Groups by
simply removing "CONFIG_":
* CONFIG_POSIX_DEVICE_IO
Similarly, with this deprecation, we introduce the following
Kconfig options that map directly to standard POSIX Options by
simply removing "CONFIG":
* CONFIG_POSIX_OPEN_MAX
In order to maintain parity with the current feature set, we
introduce the following Kconfig options.
* CONFIG_POSIX_DEVICE_IO_ALIAS_CLOSE
* CONFIG_POSIX_DEVICE_IO_ALIAS_OPEN
* CONFIG_POSIX_DEVICE_IO_ALIAS_READ
* CONFIG_POSIX_DEVICE_IO_ALIAS_WRITE
Gate open(), close(), read(), and write() via the
CONFIG_POSIX_DEVICE_IO Kconfig option and move
implementations into device_io.c, to be conformant with the
spec.
Lastly, stage function names for upcoming ZVFS work, to be
completed as part of the LTSv3 Roadmap (e.g. zvfs_open(), ..).
