utf8data.h_shipped has a large database table which is an auto-generated
decodification trie for the unicode normalization functions and it is not
necessary to carry this large table in the kernel.
Goal is to make UTF-8 encoding loadable by converting it into a module
and adding a layer between the filesystems and the utf8 module which will
load the module whenever any filesystem that needs unicode is mounted.
Unicode is the subsystem and utf8 is a charachter encoding for the
subsystem, hence first two patches in the series are renaming functions
and file name to unicode for better understanding the difference between
UTF-8 module and unicode layer.
3rd patch resolves the warning reported by kernel test robot.
Last patch in the series adds the layer and utf8 module.

Changes in v2
- Remove the duplicate file from the last patch.
- Make the wrapper functions inline.
- Remove msleep and use try_module_get() and module_put()
for ensuring that module is loaded correctly and also
doesn't get unloaded while in use.
- Resolve the warning reported by kernel test robot.
- Resolve all the checkpatch.pl warnings.
