Automatic collision detection for half-duplex mode can be enabled
by setting `collision-detection` proprety for uart hardware
in the dts file. If the transmitted bit does not match the received
bit an error is raised. This is useful in RS-485 half-duplex mode.

Certain uarts support collision detection. This is mainly used in
half-duplex scenarios, like RS-485 and raises an error when bits
output on the TX line do not match the bits received on the RX line.

Both z_arm64_exit_exc and z_arm64_exit_exc_fpu_done must be within
the same section as execution falls through here.
If z_arm64_exit_exc_fpu_done creates a section of its own then the
linker is free to disjoint the code and we absolutely don't want that.

The permission to use multiple_condvar is not granted to test
test_condvar_multiple_threads_wait_wake, which results in
bunch or permission error messages, and actually not testing
the conditional variables. This grants the permission to
the those conditional variables to the test threads. Also,
replace the k_yield() with k_msleep() to allow all created
threads time to run. A simply k_yield() might let a few to
run before the next batch of "waking" threads start to run,
resulting in some conditional variables not being initialized
but trying to wake.

Currently P4WQ supports queues with sets of user-provided
worked threads of arbitrary numbers. These threads are started
immediately upon initialisation.
This patch adds support for 3 more thread implementation options:
1. queue per thread. It adds a K_P4WQ_ARRAY_DEFINE() macro which
initialises an array of queues and threads of the same number.
These threads are then uniquely assigned to respective queues.
2. delayed start. With this option threads aren't started
immediately upon queue initialisation. Instead a new function
k_p4wq_enable_static_thread() has to be called to enable those
threads individually.
3. queue per CPU. With this option the user can assign CPU masks
to threads when calling k_p4wq_enable_static_thread().
Otherwise the cpu_mask parameter to that function is ignored.
Currently enabling this option implies option 2 above. Also so
far to enable queues per CPU the user has to use
K_P4WQ_ARRAY_DEFINE(), which means this option also implies 1
above, but both these restrictions can be relaxed in the
future if required.

Work items in P4WQ currently belong to the user before submission
and after exit from the handler, therefore, unless the handler
re-submits the item, accessing it in p4wq_loop() in such cases
is racy. To fix this we re-define work item ownership. Now the
item belongs to the P4WQ core until the user calls
k_p4wq_wait(). If the work item has its .sync flag set, the
function will sleep until the handler completes processing the
work item or until the timeout expires. If .sync isn't set and
the handler hasn't processed the item yet, the function returns
-EBUSY.

When secondary cores are booted, they use the dummy thread and

Usually Zephyr boots all secondary CPUs as a part of system
boot. Some applications however need an ability to boot on
the main CPU only and enable secondary CPUs selectively at
run-time. Add a Kconfig option to support this behaviour.
When booting CPUs on demand applications also need helpers
to initialise a dummy thread and begin threaded execution
on those CPUs, add two such helpers.

Set options that are definitely true or false to True or False in the
options dict. Add a 'getboolean' method that also allows a fallback to
False in case the option is not mentioned in .config due to unmet
dependencies. This allows calling code to just ask about the option
they are interested in, even if the .config file doesn't mention the
option at all.
Propagate this to users within the runners package and 'west sign',
taking advantage of the new build_conf property.

JLink versions like 'V7.0a' do not conform to PEP 440 version
conventions; the 'a' part is used by PEP 440 compliant versions for
alphas. It gets parsed to a legacy type by the packaging library,
which always is treated as a lower value when compared with a
conforming version string.
To fix, get the version from the shared library distributed with the
JLink tools. This has the side benefit of making the code work on
Windows. That's merely a nice to have for -nogui 1 detection for now,
but will be essential in the next commit.

Fix buffer leak in L2CAP and SMP when attempting to send over a
a connection that has been disconnected.
Both L2CAP and SMP now have ownership of the buffer in case of failure
to send it and need to unref it in case of send failure.
Change the return type of bt_l2cap_send since the user of this function
has to handle releasing of the buffer when this fails.
