Linux: support mirrored charactors

Currently, when Harfbuzz requests a mirror charactor we just abort.
This patch adds the Unicode tables required to support mirroring.

(Note: I don't actually have any webpages which trigger this code, so
it hasn't been tested.)

BUG=17563

+# Copyright (c) 1991-2008 Unicode, Inc.
+# For terms of use, see http://www.unicode.org/terms_of_use.html
+#
+# This data file lists characters that have the mirrored property
+# where there is another Unicode character that typically has a glyph
+# that is the mirror image of the original character's glyph.
+# The repertoire covered by the file is Unicode 5.1.0.
+# 
+# The file contains a list of lines with mappings from one code point
+# to another one for character-based mirroring.
+# Note that for "real" mirroring, a rendering engine needs to select
+# appropriate alternative glyphs, and that many Unicode characters do not
+# have a mirror-image Unicode character.
+# 
+# Each mapping line contains two fields, separated by a semicolon (';').
+# Each of the two fields contains a code point represented as a
+# variable-length hexadecimal value with 4 to 6 digits.
+# A comment indicates where the characters are "BEST FIT" mirroring.
+# 
+# Code points with the "mirrored" property but no appropriate mirrors are
+# listed as comments at the end of the file.
+# 
+# For information on bidi mirroring, see UAX #9: Bidirectional Algorithm,
