This functionality is is enabled by setting CONFIG_SHELL_GETOPT.
It is not active by default.
User can call following functions inside command handlers:
- shell_getopt - getopt function based on freebsd implementation
- shell_getopt_status_get - returns getopt status
Beware when getopt functionality is enabled shell will not parse
command handler to look for "-h" or "--help" options and print

Add a newer, much smaller and simpler implementation of abort and
join. No need to involve the idle thread. No need for a special code
path for self-abort. Joining a thread and waiting for an aborting one
to terminate elsewhere share an implementation. All work in both
calls happens under a single locked path with no unexpected
synchronization points.
This fixes a bug with the current implementation where the action of
z_sched_single_abort() was nonatomic, releasing the lock internally at
a point where the thread to be aborted could self-abort and confuse
the state such that it failed to abort at all.
Note that the arm32 and native_posix architectures, which have their
own thread abort implementations, now see a much simplified
"z_thread_abort()" internal API.

Various samples are using the DT_INST macros to get devicetree node
identifiers, and going from there in the usual way to get a struct
device*.
This is undesirable for preparing a simple sample application:
1. The devicetree instance number space's rules are both complicated
and irrelevant outside of device drivers. Using this number space
just to get a node identifier is distracting and confusing in this
context.
2. A basic "get the device and use the API" sample doesn't care about
the *devicetree node identifier*; it really just wants a *device*.
Introducing node identifiers at all is also kind of beside the
point.
The only good reason to use DT_INST macros is that they guarantee that
instance number 0 refers to an enabled node with a given compatible,
as long as there is at least one. But the extra complexity isn't
really worth the benefit.
Add a new DEVICE_DT_GET_ANY(compat) macro that solves both of these
problems, by returning an arbitrary device structure straight from a
compatible. This uses INST numbers behind the scenes, but that's now
an implementation detail.
This avoids introducing INST numbers or node identifiers where they
are not needed, without requiring warts like sample-specific aliases
that point at the right devicetree node.

Add helper macros for initializing a struct spi_sconfig for a SPI
device which is defined in the devicetree. They are available from C
only due to C++ compatibility issues.
For some fields, like 'frequency', we just get the value from the
standard devicetree property. For others, like the spi_cs_control
structure's 'gpio_dev', we rely on the new DEVICE_DT_GET() macro.
This patch does not change anything for controlling SPI devices that
aren't set up in devicetree. It is entirely a convenience for driver
and application code that relies on DT.

Add two new macros for getting the chip select GPIO controller from a
SPI device:
- DT_SPI_DEV_CS_GPIOS_CTLR()
- DT_INST_SPI_DEV_CS_GPIOS_CTLR()
Now that we can get struct device pointers at build time directly from
a devicetree node identifier, it's useful to be able to get a
node_id for a CS GPIO controller from the SPI device, because that's
necessary for setting up the gpio_dev in a struct spi_cs_control.

been a request or need for DT_INST_BUS() up until now, so it didn't

This commit fixes some edge cases when using net_bufs with reserved

Signed-off-by: Reto Schneider <reto.schneider@husqvarnagroup.com>
net_buf_max_len() provides the maximum number of bytes which can be put
behind the data pointer. This provides a save alternative to using the
size field of the net_buf structure directly, which does not take the
reserved bytes (headroom) into account.
This commit also replaces the usage of the size field in places where
size got used directly. Code has not been adjusted when it is easy to
recognise that the buffer does not have any reserved bytes, which is the
case after allocation or reset. Same goes for the faulty usage by
net_pkt as exposed by the last commit and begin fixed by a separate
commit.
Even though it would be cleaner, I decided to not rename the size field
to e.g. __buf_size in order to keep the amount of code changes low.
