d8c7fc8be6 shell: Fix uart_rx_handle byte processing when ring buffer full
In case when shell ring buffer gets full the data may still be taken
from the UART fifo, byte by byte, and accepted by the SMP back-end,
if the back-end has been enabled.

Unfortunately the uart_rx_handle failed to check if it has been
successfull in reading a byte from the fifo, before passing it to
the SMP for processing, which could lead to processing random stack data
as a part of an SMP frame.

Additinally, when the SMP would have accepted the byte,
the uart_rx_handle would fail to signal shell_thread, that the SMP has
internally buffered data that could be processed.

f74feca027 mgmt: smp: shell: initialize SMP before feeding with received bytes
So far SMP shell transport was initialized in APPLICATION run level, but
shell over UART was initialized in POST_KERNEL. This could end up in
situation when received frames were scheduled for further processing in
SMP layer, when it was not initialized yet.

Export smp_shell_init() function declaration and call it before shell is
initialized with all its receive data handlers. This prevents situation
when data is scheduled for processing in SMP layer, when that one is not
ready yet.

d8b86cba3c device: add API to check whether a device is ready to use
Currently this is useful only for some internal applications that
iterate over the device table, since applications can't get access to
a device that isn't ready, and devices can't be made unready.  So it's
introduced as internal API that may be exposed as device_ready() when
those conditions change.

2716cbcaa6 drivers: susbsys: Check errors on devices selected using dt macro
Some Kconfig defined devices may be defined using dt_chosen_label
function. Since there is no way to ensure a device enabled in dts
is also defined in Kconfig, it may happen that instance is not
actually defined.
In this case device_get_binding might return 0, leading to undefined
behavior in the function that calls it.
When not already done, systematically check return of function
device_get_binding on devices defined through dt_chosen_label macro.
Trigger ASSERT when required and return error when possible.

8d7bb8ffd8 device: Refactor device structures
When the device driver model got introduced, there were no concept of
SYS_INIT() which can be seen as software service. These were introduced
afterwards and reusing the device infrastructure for simplicity.
However, it meant to allocate a bit too much for something that only
required an initialization function to be called at right time.

Thus refactoring the devices structures relevantly:
- introducing struct init_entry which is a generic init end-point
- struct deviceconfig is removed and struct device owns everything now.
- SYS_INIT() generates only a struct init_entry via calling
  INIT_ENTRY_DEFINE()
- DEVICE_AND_API_INIT() generates a struct device and calls
  INIT_ENTRY_DEFINE()
- init objects sections are in ROM
- device objects sections are in RAM (but will end up in ROM once they
  will be 'constified')

It also generate a tiny memory gain on both ROM and RAM, which is nice.

Perhaps kernel/device.c could be renamed to something more relevant.

32bb2395c2 timeout: Fix up API usage
Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them.  Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:

+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
  values for equality (e.g. with K_FOREVER or K_NO_WAIT).

+ Adding a k_msleep() synonym for k_sleep() which can continue to take
  integral arguments as k_sleep() moves away to timeout arguments.

+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
  generate timeout arguments.

+ Removing the usage of K_NO_WAIT as the final argument to
  K_THREAD_DEFINE().  This is just a count of milliseconds and we need
  to use a zero.

This patch include no logic changes and should not affect generated
code at all.

There is now a centralized declaration in kernel_internal.h.

On uniprocessor systems, z_interrupt_stacks has one element
and can be used in the same way as _interrupt_stack.

The IRQ stack for CPU 0 is now set in init.c instead of in
arch code.

The extern definition of the main thread stack is now removed,
this doesn't need to be in a header.
