Under GNU C, sizeof(void) = 1. This commit simply uses uint8_t.
Pointer arithmetics over void types is:
* A GNU C extension
* Not supported by Clang
* Illegal across all ISO C standards

This patch introduce version which fixes following bug:
While inode is updated it is possible that Garbage Collection
is called which caused overwrite of inode's filename as the same
buffer was used to keep the filename and copping data in GC.
This patch uses buffer on the stack for keeping filename while inode
is updated which fix the issue.
The patch cause 128 B increase of stack consumption during inode
update the file name might be corrupted

Add support for enabling multiple disk interfaces (Flash, RAM)
simultaneously in Zephyr by introducing a simple disk interface
framework where we can register multiple disks which would
interface with different storage devices. This would enable us
to have multiple instances of FATFS in Zephyr.
Add support for mass storage drive disk name which will be
used as an argument when calling the disk interface API's.
Enable multiple volumes support configuration in
ELM FAT library.

The argument is a u32_t which limits the maximum disk size to 4 GiB.
Rather than fix this, delete the ioctl and switch the only use to
GET_SECTOR_COUNT instead.

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

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 implementation was using different typedefs than the prototypes
in the header.

Modified the Kconfig flag names to identify external FS
with source. This is required to differentiate between
additional external Fat FS code tht may be added in future.

This implements the top layer of the FAT FS. It exports an user API
that would be abstacted by Zephyr FS API. It has another set of API
to interface with a bottom layer that would provide platform specific
file systems. A flash file system will be implemented for the bottom
layer.
