394f8a9c4b Unicode: Add script to facilitate UCD update
Add a script that downloads UCD data for a given Unicode version,
unpacks it, and copies the used files to appropriate locations inside
the Qt source code.

Also update the README and use an HTTPS link for the UCD data file.
FTP links are no longer supported by some browsers.

4e460aa3f7 tests: Add test for UTS #46 implementation using Unicode data
The new test is called tst_qurluts46. It verifies QUrl::{to,from}Ace()
functionality using the data from IdnaTestV2.txt supplied by Unicode.

The file was downloaded from
https://www.unicode.org/Public/idna/13.0.0/IdnaTestV2.txt

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.

1a1718b342 Add missing docs for UCD additions at 5.15
Also remove two stray commas pointed out in code-review and some
others noticed on checking for similar.
This amends commit c3eb521a0f.

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.

6852ba815d Correct some references to corelib/tools/ to say corelib/text/
The Unicode data tables moved with QString and friends.
So did the locale data generated from CLDR.

This amends commit a9aa206b7b.

d38f635355 Clean up and update Unicode character data 3rd-party infrastructure
Document how to do an update, fix the bit-rot that had crept into
main.cpp since last it was compiled, correct the qt_attribution.json
to use the actual version number of UCD (its Revision number) instead
of the (admittedly correlated) Unicode release number.  Updated to
Release 22 (which came with Unicode 11.0.0) in the process; but this
doesn't change our actual qunicodetables.cpp (so is incidental).
