In certain scenarios, the semaphore sem_ticker_api_cb may be taken
during attempt to complete a synchronous ticker operation such as start
or stop, but is never released via ull_ticker_status_give. This could
happen if ticker temporarily runs out of ticker operation slots for any
ticker client.
The consequence of ULL stuck waiting in semaphore is anything from
allocation assertions to watchdog timeouts.
This commit also sets a timeout on ull_disable calls, which relies on
the disable callback being invoked from 'done'. Invocation of 'done' is
mandatory, and code shall not allow that not to happen, but to avoid
hiding the real cause, the semaphore now has a timeout which causes
assertion in the location the issue occurred.

Check mayfly_is_running() to determine use of blocking- or non-blocking
version of lll_csrand, instead of k_is_in_isr().
As mayflies run in ISR context for Nordic platform, change will have no
impact on Nordic configuration.
For vendors using META_IRQ mayflies, implementation will now prevent
blocking and reduce latencies and jitter in soft-realtime code.

Using a different channel for responding to a request is forbidden by spec.
The allocator was especially flawed as it iterated over all the EATT
channels to find one w/ a big enough MTU, but the sending was still done
over the same channel as the REQ.

This to ensure we don't fail to send a response and never get an ATT
TIMEOUT due to ACL TX buffer starvation caused by other users of the stack.
Signed-off-by: Jonathan Rico <jonathan.rico@nordicsemi.no>
The ATT module has provisions to queue a packet/buffer for sending later if
it can't send it right away. For example if the conn.c tx context
allocation fails.
This unfortunately doesn't work if the buffer can't get allocated in the
first place, or if the ATT metadata can't also be allocated.
The metadata is allocated from a global pool set to the same number as
conn.c TX contexts. That can lead to a situation where other users of ATT
manage to queue a bunch of buffers (e.g. the app spamming GATT
notifications), depleting the number of ATT metadata slots so that none are
available.
When none are available, and we receive an ATT REQ, we try to allocate one,
fail, and drop the buffer (!). That pretty much guarantees an ATT timeout.
As a workaround for this, use a per-channel metadata slot, that is only
used for completing transactions.

This is useful in multilink scenarios, especially since there is not user
callback when the ATT channel times out.
Adding a user-facing callback should ideally also be done, but just logging
the address already provides useful insight.

Easier to debug that way.
Ideally we'd have more error codes/logging instead of just returning
UNLIKELY for most errors.

Upon receiving a L2CAP PDU, only send credits back if the L2CAP channel

This was recently refactored (in #58440). But it introduced a bug in which
some channels were connected but not the whole list asked for by the peer.
In that case, `result` will not be `SUCCESS` but we still want to call the
`connected` callback as the peer will consider those channels to be
connected when we send the response.
The symptom is that EATT channels are being instantiated, but not
considered connected (ie. usable by the stack).
Also introduce a test that has asymmetric channel resources (5 on central
vs 2 on peripheral) to reproduce the bug.
Fixes#60212

Updates the handling of incoming seg ack messages to comply with
the mesh protocol specification, section 3.5.3.3.2 and section
3.5.3.3.3.
Previous implementation did not restart the retransmission timer unless
the incoming ack contained at least one segment newly marked as
acknowledged. According to the spec, the timer should be restated
regardless. The implementation depends on the retransmission
timer to end the transmission early if there was no more retransmission
attempts. Checks have been added to ensure that this now happens
immediately.
