Ramakrishna Pallala dd5449a77b subsys: fs: Add the support for multiple instances of fs
Add support for multiple instances of a file system by
making use of mount point as the disk volume name which
is used by the file system library while formatting or
mounting a disk.

Also moved out file system specific data structures from
public fs.h header and handled them in corresponding
file system interface files by introducing open files and
open directories concept which is already being used in
NFFS interface module. Now it is extended to FatFs as well.

Ramakrishna Pallala 25302b1980 subsys: fs: Add Virtual File system Switch (VFS) support
Add support for Virtual File system Switch (VFS) by
introducing mount point concept to Zephyr. This allows
the applications to mount multiple file systems at
different mount points (ex: "/fatfs" and "/nffs"). The
mount point structure contains all the necessary info
required to instantiate, mount and operate on file system.

Decouple applications from directly accessing individual
file systems API's or internal functions by introducing
file system registration mechanism in VFS.

Move the file system defination and mount responsibility
to application so that application can decide which file system
to use and where to mount.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
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.

Jithu Joseph 2fe288b4aa fs: expose generic ramdisk/flash disk access functions
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.

Johan Hedberg b108d02eba fs: Make API naming adhere to the appropriate namespace
The namespace allocated for the filesystem API is fs_* and FS_*. That
means all symbols and defines should adhere to it.
