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.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

The NVS data lookup time grows linearly with the number of
allocation table entries to walk through, meaning that if
some data pair in the NVS changes frequently, access to
other data pairs that change rarely can take a lot of time.
It is particularly visible when the NVS is used as the
settings backend since the backend needs to perform multiple
NVS reads to find a requested key.
Implement a simple cache that stores an address of the most
recent ATE for all NVS IDs that fall into the given cache
position. CRC8/16 is used as a hash function used to
distribute NVS IDs across the cache entries.
The cache entries are only invalidated when an NVS sector
is erased as part of the garbage collector task.

Signed-off-by: Peter Bigot <peter.bigot@nordicsemi.no>
Originally the file cache used a mem_pool, but that data structure has
been deprecated and replaced by a heap that includes metadata in the
heap area. As a result attempts to allocate all blocks will fail
because some of the reservation intended for cache data is now holding
metadata instead.
It's not immediately clear how to adjust the required heap size to
support this metadata as it depends on heap chunk units and data
structures that are not visible to the application. Experimentally a
value of 24 bytes works, while smaller values do not.
Further the previous Kconfig API to configure the allocation pool is
completely inappropriate with the new heap data structure which has
such different behavior.
So: Deprecate the old Kconfig API. Add a new Kconfig option to
directly control the cache size. Infer a default cache size that
works with the old mem_pool parameters assuming a per-block overhead.
But to avoid wasted memory use the heap allocation only when the
application customizes the size, and use a slab in other cases.
