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. Last patch in the series adds the layer and utf8 module.
