Systems that enabled this option don't have their stacks in coherent
memory. Given our pipe_buf_spec is stored on the stack, and readers may
also have their destination buffer on their stack too, it is not worth
going to the trouble of supporting direct-to-readers copy with them.

We are waking up threads but failed to let them run if they are
higher priority. Add missing calls to z_reschedule().
Also wake up all pending writers as we don't know how many there might
be. It is more efficient to wake them all when the ring buffer is full
before reading from it rather than waking them one by one whenever there is
more room in it.
Thanks to Peter Mitsis for noticing those issues.

If there are pending readers, it is best to perform a single data copy
directly into their final destination buffer rather than doing one copy
into the ring buffer just to immediately copy the same data out of it.
Incidentally, this allows for supporting pipes with no ring buffer at all.
The pipe implementation being deprecated has a similar capability so better
have it here too.

kernel: poll: Allow 0 event input
Allows `k_poll` to be user with 0 events, which is useful for allowing just
a sleep without having to create artificial events.
Allow the same for `k_work_submit_to_queue()` and `k_work_submit()`.

Currently various zbus functions silently change the timeout
to zero when inside an ISR. If a developer is not aware
of this it could lead to unexpected behaviour or a
publish/read failing.
Also in the zbus docs it states to only use a timeout of
zero when inside a ISR multiple times.

The algorithm for matching request with response was incorrect, which
could lead to false matches (for example if request had a token, and
piggybacked reply had no token but matching message ID only, that would
still be counted as a match).
This commit fixes it. The request/reply matching is implemented based on
RFC now, with separate conditions for piggybacked/separate responses.

DMA transfers are supposed to write to buffer tail. Use the proper
pointer to make multipart DMA transfers actually write the data to the
intended location.
The issue was observed on control write transfers where the OUT Data
Stage was at least 128 bytes (because endpoint 0 transfer width is
limited to 7 bits).
The issue is unlikely to happen on non-control transfers because the
transfer size width is at least 11 bits (at most 19 bits) and packet
size counter is at least 4 bits (at most: 10 bits) which means that
at least 2048 byte transfer spanning at least 15 packets (or at least
524288 byte spanning 1023 packets for 19 bits transfer size counter
and 10 bits packet counter) is required to necessitate multipart DMA.

In order to show how to use OpenThread and CoAP, add an application.
This example could be build to run a client or server.
The server could expose LEDs and buttons and client could get their
state and set the LEDs state.
The network is created automatically using the network key predefined
in the config. The goal is to make the example simple by removing
the commisionning and joinning process.
If a client application has a button, it could use it to toggle the first
