9b0fab6b62 Update Qt internals to use QChar::Script
...and remove the outdated QUnicodeTables::Script enum.
QFontEngineData now has one extra slot that never used
(engines[QChar::Script_Inherited]). engines[QChar::Script_Unknown],
if accessed, would be set with a Box engine instance, and could be used
as a minor optimization some time later.

In order to preserve the existing behavior, we map all scripts up to Latin to Common.

f7639c0a6d Add QChar::Script enum
...where the values are not aliased to Common script.

The old QUnicodeTables::Script enum was retained for compatibility reasons
until Qt internals are updated to use QChar::script().
Using QChar::Script instead of QUnicodeTables::Script would improve both
the text analysis (itemization, boundary finding) and the text shaping quality.
This also a required step for switching to Hurfbuzz-NG.

/* This adds 6668 more .rodata bytes */

2fbb69a093 QTBF: Fix issue with no splitting the words at "." (FULL STOP)
As of Unicode 5.1, some punctuation marks were mapped to MidLetter and MidNumLet
for better URL and abbreviations handling which caused "hi.there" to be treated
like if it were just a single word;
until we have the Unicode Text Segmentation tailoring mechanism, retain
the old behavior by remapping (some of) those characters back to their old values.

2672c4fa91 Update the Unicode Data and Algorithms up to Unicode 6.2
Version 6.2 of the Unicode Standard is a special release
dedicated to the early publication of the newly encoded Turkish lira sign.
In addition, there are some significant changes to the Unicode algorithms
for text segmentation and line breaking to improve breaking for emoji symbols.

For more details, see http://www.unicode.org/versions/Unicode6.2.0/

b57e2162ef QUnicodeTables: some internal API renamings
enums GraphemeBreak, WordBreak, and SentenceBreak has been renamed to
GraphemeBreakClass, WordBreakClass, and SentenceBreakClass respectively,
their values has been renamed to contain a '_' as logical enum-value separator
(just like many other nums in Qt, e.g. LineBreakClass);
*BreakFormat has been replaced with *Break_Extend (some format characters are
kind of subtype of the extender characters, not vice versa).

c1329fba13 Clean-up the Unicode tables generator code and the generated header
This fixes the blocks and memory consumption reports, the whitespace issues
and makes the code a bit cleaner.

Since I'm the only one who does change this code, such a no-op commit
could not hurt anyone or even git blame ;)

d8c04d60db Make QUnicodeTables::script() support SMP code points
Instead of expanding the scripts table with script values for the code points
>= 0x10000, it has been merged with the properties table in order to
increase perfomance of the script itemization code (not affected yet).
(Stats: the properties table grew up in 97428-89800 = 7628 bytes;
        the old scripts table was of size 7680 bytes)

The outdated ScriptsInitial.txt and ScriptsCorrections.txt file has been removed
(they were just empty, the "corrigendum" script corrections should be applied
to Scripts.txt directly, *no customization allowed*!).

More script testcases has been added - at least one per supported script.

Task-number: QTBUG-6530

3fe02eaa12 significant unicodetables generator performance optimization
since the entire range of a valid unicode code points is in use, QHash
is suboptimal and could be replaced with QList;
taking the value by ref and not inserting it back to the map + not calculating
the default value over and over gains us up to 60% performance boost!

46b78113b2 add support for non-BMP ligatures
> http://www.unicode.org/versions/Unicode5.2.0/
D. Character Additions:
There are three new characters in the newly-encoded Kaithi script that will
require changes in implementations which make hard-coded assumptions about
composition during normalization. Most new characters added to the standard
with decompositions cannot be generated by the operations toNFC() or toNFKC),
but these three can. Implementers should check their code carefully
to ensure that it handles these three characters correctly.
U+1109A KAITHI LETTER DDDHA
U+1109C KAITHI LETTER RHA
U+110AB KAITHI LETTER VA

UCD 6.1 adds two more of them:
U+1112E CHAKMA VOWEL SIGN O
U+1112F CHAKMA VOWEL SIGN AU

two more of them were added in the Unicode 6.0:
  U+0265  LATIN SMALL LETTER TURNED H
  U+A78D  LATIN CAPITAL LETTER TURNED H
and two more were added in the Unicode 6.1:
  U+0266  LATIN SMALL LETTER H WITH HOOK
  U+A7AA  LATIN CAPITAL LETTER H WITH HOOK

we map them like special cases with length == 1
(note: all are in BMP which is checked explicitly in the generator)
