Move the network buffer header file from zephyr/net/buf.h to
zephyr/net_buf.h as the implementation now lives outside of the networking
subsystem.
Add (deprecated) zephyr/net/buf.h header to maintain compatibility with old
file path.

This adds a kconfig option to force

The shell UART TX code would only disable the TX IRQ when no data was
available in the TX ring buffer. However, it should also disable the IRQ
when all data retrieved from the buffer has been written. Otherwise it
will just result in another immediate TX IRQ which results in the IRQ
finally being disabled.
For this to work, since ring_buf_get_claim may not always return all
available data in the ring buffer on a single call, we need to loop
until either no data is left in the ring buffer or the UART was unable
to consume any of the data.

Return availability of free buffers after data is consumed. This
information may be important for the module using uart_async_rx to
schedule next reception if there is a new buffer available.

Rework UART backend to clearly use single instance approach as
before it was a bit messy with some parts of implementation indicating
multi-instance approach and some single instance. Backend has been
around for years and multi-instance requirement never came.
Added support for UART asynchronous API which is more efficient
in terms of power consumption and performance. Asynchronous API
support is using uart_async_rx helper module for handling data
received asynchronously.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Fail compilation when incorrect configuration is detected, i.e. when
SHELL_BACKEND_SERIAL_CHECK_DTR is set but UART_LINE_CTRL is not set.
Use periodic timer to wait for DTR instead of waiting in uart callback
to prevent blocking caller workqueue and/or sleeping in ISR.
DTR check was only ever supported with interrupt driven backend so add
appropriate depends on to Kconfig.

Many device pointers are initialized at compile and never changed. This
means that the device pointer can be constified (immutable).
