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. Fixes: 2b3d047 ("unicode: Add utf8-data module") Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Reviewed-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Gabriel Krisman Bertazi <krisman@collabora.com>
