Update the files which contain no license information with the
'Apache-2.0' SPDX license identifier. Many source files in the tree are
missing licensing information, which makes it harder for compliance
tools to determine the correct license.
By default all files without license information are under the default
license of Zephyr, which is Apache version 2.

The return of memset is never checked. This patch explicitly ignore
the return to avoid MISRA-C violations.
The only directory excluded directory was ext/* since it contains
only imported code.

Bool symbols implicitly default to 'n'.
A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.
Remove some 'default ""' properties on string symbols too.
Also make definitions more consistent by converting some
config FOO
<type>
prompt "foo"
definitions to a shorter form:
config FOO
<type> "foo"
This shorthand works for int/hex/string symbols too, not just for bool
symbols.

This is bug-fix for issue #7311

write size.

FS_FLASH_MAP_STORAGE keyword enables the storage partition,
but it was depend on flash_map module which is unused by
NFFS. This patch makes it independent thanks
to it is possible to enable the storage partition
without flash_map module.
FS_FLASH_MAP_STORAGE was renamed to
CONFIG_FS_FLASH_STORAGE_PARTITION
as it is independent for flash_map.

The NFFS partition at the end of flash is also useful for any other
file system or even the Flash Circular Buffer (FCB). Rename the
partition from 'nffs_partition' to 'storage_partition' and make it
depend on a new hidden Kconfig entry which the relevant users will
select (such as NFFS and FCB).

It is faster to operate directly on flash_area pointer instead
of fetch it all the time using the fcb flash area id.
Also as f_area_id was needed only for get appropriate flash_area
pointer, so it is better to pass it only while initialization
the fcb and not store it in fcb instance data at all.

Previously flash_area structure was the parameter for the callback
function for transferring sector location info.
Now flash_sector is used so relevant flash_area is missing for
the callback.
This patch introduces structure fcb_entry_ctx which incorporates
entries' location and relevant flash area. It is used to pass complete
information to the callback. Additional pointer to the flash_area fcb
speeds up operations.

Prior to this commit: `struct fcb` contained a pointer to an array of
`struct flash_area`. Each entry in the array represented a flash sector
that the fcb comprised.
After commit: `struct fcb` contains a pointer to an array of `struct
flash_sector`, not `struct flash_area`.
Rationale: The FCB needs to know which sectors it occupies for its
rotate operation. However, the `flash_area` type is meant to represent
a collection of sectors, not a single sector. `struct flash_area`
contains information that the fcb does not need (e.g., area ID and
device ID). Furthermore, the flash_map API provides a means of
converting a flash area ID to an array of sectors
(`flash_area_get_sectors()`), but no way to convert to an array of
areas.

Zephyr already supports NFFS as a storage layer, but it might
be a little bit too heavyweight for certain applications in
memory-restricted ICs.
This module is response for need of Lightweight flash storage
capability. FCB is ported form MyNewt as native zephyr module.
