7832738ae9 kernel/timeout: Make timeout arguments an opaque type
Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument.  Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created.  This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.

The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.

The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.

Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.

For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided.  When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.

Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions.  These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig.  These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.

k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.

Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate.  Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure.  But k_poll() does not fail
spuriously, so the loop was removed.

80917ec16f net: Add preliminaly support for suspending/resuming a net interface
Such state needs to be set _from_ the PM API functions and not the other
way round. So if a network device driver does not support such API, it
will not be able to set the core net_if on PM state, obviously.

Currently, these functions only set/unset NET_IF_SUSPENDED flag.

More logic will be added later, to decide whether the net_if can be
actually set to suspend mode or not and also to take care of all timers
related to the interface.

15dfa28c2e net: tc: Return information whether TX pkt was queued
We need to know whether the net_pkt was successfully placed
to transmit queue. It is possible in TX side, that the net_pkt
is already in TX queue when for example TCP packet is
re-transmitted, in which case the queue submit will fail.
This cannot happen in RX side as there are no timers involved.

It is required to check about such pending flag before trying to submit
it into the queue. Indeed, the work queue could be scheduled right after
such queuing, thus checking for the pending flag afterwards would
provide a false information.

It is unfortunate k_work_submit_to_queue() does not return anything as
it would simplify the code then.

with following code:

This resulted in invalid log, since they were not NULL-terminated

sure they are NULL-terminated now and valid to print and

9f9e00a62d net: mqtt: Added event for MQTT ping response.
There are scenarios where there is a NAT firewall in between MQTT
client and server. In such case, the NAT TCP timeout may be shorter
than MQTT keepalive timeout and TCP timeout. The the MQTT ping
request message is dropped by the NAT firewall, so that it cannot be
received by the server, resulting in void MQTT ping response message.
There is no TCP FIN or RST at all. The application looks hang-up
until TCP timeout happens on the client side, which may take too
long.

Therefore, the event MQTT_EVT_PINGRESP is added to inform the
application that the route between client and server is still valid.

This commit updates the the IPv4 ping command to handle the ENETUNREACH
error number returned by `net_icmpv4_send_echo_request` function when
IPv4 is unavailable.

The `net_icmpv4_send_echo_request` function previously returned EINVAL
when IPv4 is unavailable and this caused the shell command to report
"Invalid IP address" even when the provided IP address is correct; this
problem was corrected by returning ENETUNREACH instead of EINVAL in the
aforementioned function.
