When threads are in more than one state at a time, k_thread_state_str()
returns a string that lists each of its states delimited by a '+'.
This in turn necessitates a change to the API that includes both a
pointer to the buffer to use for the string and the size of the buffer.

Commit f7c4fe6778 ("shell: optimize history storage a bit") forgot
to distinguish between the newly allocated history item and the previous
one, causing havoc on ring buffer wraparounds with excess padding.
Signed-off-by: Nicolas Pitre <npitre@baylibre.com>
When padding is added to "fill" the gap in order to wrap to the
beginning of the ring buffer, such padding is attributed to the
current item being added. Let's attribute it to the previous entry
instead so it'll be freed along with that entry and make the space
available one entry sooner, increasing the chances for keeping the
current entry around longer.
If ring buffer is empty then always reset it up front to get best
alignment right away i.e. beginning of buffer.

Make it possible to "finish" with fewer bytes than what was "claimed".
This was possible before on the get side, but the put side was
cummulative wrt finish. The revamp made it cummulative on both sides.
Turns out that existing users rely on the opposite behavior which is
more logical and useful. So make both sides that way.
Adjust documentation, test case and users accordingly.
Signed-off-by: Nicolas Pitre <npitre@baylibre.com>
No ring_buf_get_finish() should be performed on ring_buf memory that
wasn't claimed beforehand. Using ring_buf_get() with a NULL destination
does both the claim and the finish part without retrieving anything.
This is especially important with the ring_buffer revanp where the above
is enforced for proper operation.

which can be used to explicitly select deprecated version.

Getopt has been rework in this way that calling it does not require
extra state parameter and its execution is thread safe.
Global parameters describing the state of the getopt function have been
made available to ensure full API compatibility in using this library.
However, referencing these global variables directly is not thread
safe. In order to get the state of the getopt function for the thread
that is currently using it, call: getopt_state_get();
Extended the library with getopt_long and getopt_long_only functions.
Moved getopt libary from utils to posix.

When logging is using immediate mode then logging messages
can be processed from any context, including interrupt context.
z_shell_fprintf was asserting in that case since it allowed to
be called from interrupt context only when logging was in panic
mode. However, shell works in the same way when logging is in
immediate mode as in panic mode.
Renamed internal shell flag from panic_mode to sync_mode. Flag
is also set when shell log backend is started in synchronous
mode (immediate logging) which prevents assertion.

The device PM subsystem _depends_ on device, not vice-versa. Devices
only hold a reference to struct pm_device now, and initialize this
reference with the value provided in Z_DEVICE_DEFINE. This requirement
can be solved with a forward struct declaration, meaning there is no
need to include device PM headers.

Remove LOG_MINIMAL kconfig option which was confusing
since LOG_MODE_MINIMAL existed. LOG_MINIMAL was used to
force minimal mode but because of invalid dependencies
it was leading to issues.

renamed LOG_MINIMAL to LOG_DEFAULT_MINIMAL which has impact
on defualt logging mode (which still can be later changed

This patch fixes the issue that can cause a deadlock in shell.
When two threads simultaneously poll the TXDONE signal, only one
of them will receive it, leaving second one stalled.
The problem was that shell's context contains k_poll_event objects that
were polled by multiple threads. Polling it overwrites the poller field
that was set by previous thread.
Instead, the k_poll_event object must be created on the stack by every
thread that wants to poll the TXDONE signal.
This makes sure that no thread will be left waiting for this signal
forever.

Problem:
In some cases, as described in: https://github.com/zephyrproject-rtos/zephyr/issues/36948
shell backend sends characters to output before serial device
is ready for it. It results in observing additional characters

Added waiting on DTR signal before sending anything to the output.
