In the file gatt.c, GAP service contains the Device Name
characteristic. If writable, authentication and authorization may
be defined by a higher layer specification.It means that GATT
clients can write to device name GAP characteristic without

9d0fb5ec47 Bluetooth: ISO: Remove channel direction
Channel direction was actually a source of confusion since the spec does
actually define the data path direction from controller point of view
meaning input actually means transmit and output receive, also direction
can be configured with different QoS settings.

To make these APIs less confusing and allow QoS to be configured
independently they are now split into RX (receiving) and TX
(transmission) settings including its data path.

b10428163a kernel: sem: add K_SEM_MAX_LIMIT
Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".

Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.

In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.

These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.
