[PATCH RFC v5 01/11] unicode: Add unicode character database files

[Gabriel Krisman Bertazi <krisman@collabora.com>]

From: Olaf Weber <olaf@sgi.com>

Add files from the Unicode Character Database, version 11.0, to the
source.  A helper program that generates a trie used for normalization
from these files is part of a separate commit.

- Notes on the update from 8.0.0 and 11.0:

The structure of ucd files and special cases have not experienced any
changes between versions 8.0.0 and 11.0.0.  8.0.0 saw the addition of
Cherokee LC characters, which is an interesting case for case-folding.
The update is accompanied by new tests on the test_ucd module to catch
specific cases.  No changes to mkutf8data script was required for the
update.

The actual files are not part of the commit submitted to the list
because they are to big and would bounce.  Still, they can be obtained
by the following script:

FILES="CaseFolding.txt DerivedAge.txt extracted/DerivedCombiningClass.txt
       DerivedCoreProperties.txt NormalizationCorrections.txt
       NormalizationTest.txt UnicodeData.txt"
VERSION=11.0.0
BASE=http://www.unicode.org/Public/${VERSION}/ucd

for i in ${FILES} ; do
  wget "${BASE}/$i" -O fs/unicode/ucd/$(basename ${i} .txt)-${VERSION}.txt
done
