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. Signed-off-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com>
