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.

Of the filesystems under subsys/fs/, only the ELM FAT filesystem needs
the disk layer as others (like NFFS) talk directly to the flash API.
This removes the need to define CONFIG_DISK_ERASE_BLOCK_SIZE and
similar which are used by the disk subsystem but not by NFFS.

Introducing CMake is an important step in a larger effort to make
Zephyr easy to use for application developers working on different
platforms with different development environment needs.
Simplified, this change retains Kconfig as-is, and replaces all
Makefiles with CMakeLists.txt. The DSL-like Make language that KBuild
offers is replaced by a set of CMake extentions. These extentions have
either provided simple one-to-one translations of KBuild features or
introduced new concepts that replace KBuild concepts.
This is a breaking change for existing test infrastructure and build
scripts that are maintained out-of-tree. But for FW itself, no porting
should be necessary.
For users that just want to continue their work with minimal
disruption the following should suffice:
Install CMake 3.8.2+
Port any out-of-tree Makefiles to CMake.
Learn the absolute minimum about the new command line interface:
$ cd samples/hello_world
$ mkdir build && cd build
$ cmake -DBOARD=nrf52_pca10040 ..
$ cd build
$ make

Add following commands to fs shell:
- rf <filename>
- read <filename> [<offset> [<length>]]
- write <filename> [-o <offset>] <byte1> [<byte2> ... [<byteN>]]
- trunc <filename> [<length>]
For writes without offset specified, new data is appended to file.
For truncaces without length specified, 0 is default value.

Convert code to use u{8,16,32,64}_t and s{8,16,32,64}_t instead of C99
integer types.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

The fat library uses its own typedef for integer parms and expects a
UINT to be either 16 or 32-bits in length. We potentially get into
trouble when we build with newlib if we use an uint32_t. Lets just use
unsigned int which should cover all cases for us.

Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.
Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.
Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file. Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

This moves the shell component into its own subsys and groups all
related files and options into a single place.
Additionally, one Kconfig option will now be required to enable the
shell:
CONFIG_CONSOLE_SHELL=y
The header files was also moved to include/shell/shell.h and can be now
referenced with
#include <shell/shell.h>
instead of
#include <misc/shell.h>
Updated documentation as well.

This patch removes "FAT" from files names, config names and
symbol names so as to avoid confusion, when other modules use
them in a more generic way.
Also flash_disk_access.c and ram_disk_access.c now exports generic
disk_access symbols as defined in include/disk_access.h rather
than FAT specific ones in fs/fat_diskio.h. Thus modules like
USB which need to use disk_access interface is not dependent
on symbols from ELMChan FAT module. Also fat_diskio.h
is removed.
Further the shim between ELM chan and Zephyr is modified as
per these changes.

The flash and RAM disk options are mutually exclusive (evident e.g. in
both defining FS_VOLUME_SIZE and FS_BLOCK_SIZE variables), so they
should really be inside a choice-endchoice block. The duplicated
options can also taken care of with a single definition using
conditional default values.
