Christoph Hellwig 5298d4bfe8 unicode: clean up the Kconfig symbol confusion 
Turn the CONFIG_UNICODE symbol into a tristate that generates some always
built in code and remove the confusing CONFIG_UNICODE_UTF8_DATA symbol.

Note that a lot of the IS_ENABLED() checks could be turned from cpp
statements into normal ifs, but this change is intended to be fairly
mechanic, so that should be cleaned up later.

To update to the newer version of the Unicode standard, the latest
released version of the UCD can be found here:

  http://www.unicode.org/Public/UCD/latest/

Then, build under fs/unicode/ with REGENERATE_UTF8DATA=1:

	make REGENERATE_UTF8DATA=1 fs/unicode/

After sanity checking the newly generated utf8data.h file (the
version generated from the 12.1.0 UCD should be 4,109 lines long, and
have a total size of 324k) and/or comparing it with the older version
of utf8data.h_shipped, rename it to utf8data.h_shipped.

If you are a kernel developer updating to a newer version of the
Unicode Character Database, please update this README.utf8data file
with the version of the UCD that was used, the md5sum and sha1sums of
the *.txt files, before checking in the new versions of the utf8data.h
and README.utf8data files.
