utf8data.h contains a large database table which is an auto-generated
decodification trie for the unicode normalization functions.
Allow building it into a separate module.

Instead of repeatedly looking up the version add pointers to the
NFD and NFD+CF tables to struct unicode_map, and pass a
unicode_map plus index to the functions using the normalization
tables.

Only used by the tests, so no need to keep it in the core.

Just use the utf8nlen implementation with a (size_t)-1 len argument,
similar to utf8_lookup. Also move the function to utf8-selftest.c, as
it isn't used anywhere else.

Don't bother with pointless string parsing when the caller can just pass
the version in the format that the core expects. Also remove the
fallback to the latest version that none of the callers actually uses.

Move the static keyword to the front of declarations of nfdi_test_data
and nfdicf_test_data, and resolve the following compiler warnings that
can be seen when building with warnings enabled (W=1):
fs/unicode/utf8-selftest.c:38:1: warning:
‘static’ is not at beginning of declaration [-Wold-style-declaration]
fs/unicode/utf8-selftest.c:92:1: warning:
‘static’ is not at beginning of declaration [-Wold-style-declaration]

This implements a in-kernel sanity test module for the utf8
normalization core. At probe time, it will run basic sequences through
the utf8n core, to identify problems will equivalent sequences and
normalization/casefold code. This is supposed to be useful for
regression testing when adding support for a new version of utf8 to
linux.
