826fc8c9bd Update UCD to Revision 28
This corresponds to Unicode version 14.0.0.

Added the following scripts:

    * CyproMinoan
    * OldUyghur
    * Tangsa
    * Toto
    * Vithkuqi

Full support of these scripts requires harfbuzz version 3.0.0,
this version adds support for Unicode 14.0:

    https://github.com/harfbuzz/harfbuzz/releases/tag/3.0.0

With this release 10 test cases in tst_qurluts46 were fixed, one
additional test case is failing in tst_qtextboundaryfinder and
is commented out. In total 62 line break test cases and 44 word
break test cases are failing.

A comment in src/corelib/text/qt_attribution.json was updated to
include the URL of the page containing UCD version number.

2afe1a3c19 unicode: Generate tables for IDNA/UTS #46
Update the Unicode data processing tool to generate properties
and mapping tables needed to implement UTS #46
(https://unicode.org/reports/tr46/). The implementation extends
the standard to allow usage of underscores in URLs. This is done
for compatibility with DNS-SD and SMB protocols.

The data file needed to generate the new properties was taken from
https://www.unicode.org/Public/idna/13.0.0/IdnaMappingTable.txt

a794c5e287 Unicode: fix the extended grapheme cluster algorithm
UAX #29 in Unicode 11 changed the EGC algorithm to its current form.
Although Qt has upgraded the Unicode tables all the way up to
Unicode 13, the algorithm has never been adapted; in other words,
it has been working by chance for years. Luckily, MOST
of the cases were dealt with correctly, but emoji handling
actually manages to break it.

This commit:

* Adds parsing of emoji-data.txt into the unicode table generator.
  That is necessary to extract the Extended_Pictographic property,
  which is used by the EGC algorithm.

* Regenerates the tables.

* Removes some obsoleted grapheme cluster break properties, and
  adds the ones added in the meanwhile.

* Rewrites the EGC algorithm according to Unicode 13. This is
  done by simplifying a lot the lookup table. Some rules (GB11,
  GB12, GB13) can't be done by the table alone so some hand-rolled
  code is necessary in that case.

* Thanks to these fixes, the complete upstream GraphemeBreakTest
  now passes. Remove the "edited" version that ignored some rows
  (because they were failing).

54f8be6cc0 Update UCD to Revision 26
Include WordBreakTest.html, since a test uses sample strings from it,
albeit without actually reading the file.

Had to comment out more of the new tests, as at Revision 24, pending
an update to harfbuzz and the text boundary detection code.

c3eb521a0f Update UCD data to Unicode 12.1.0's Revision 24
Had to teach the update program to accept category Lm as for
Joining_Transparent, for the sake of a new ArabicShaping.txt entry.
Added three new Unicode versions, several new scripts and a new
word-break class.

Updated UCD's test data for tst_QTextBoundaryFinder.  This left 57
tests failing; I have commented out the data rows for those tests,
pending someone with more knowledge addressing this.

The text segmentation data is not being updated in this change,
as it requires additional code changes. Updating those will

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.

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.
