Alexander Barkov 133446828c MDEV-27009 Add UCA-14.0.0 collations 
- Added one neutral and 22 tailored (language specific) collations based on
  Unicode Collation Algorithm version 14.0.0.

  Collations were added for Unicode character sets
  utf8mb3, utf8mb4, ucs2, utf16, utf32.

  Every tailoring was added with four accent and case
  sensitivity flag combinations, e.g:

  * utf8mb4_uca1400_swedish_as_cs
  * utf8mb4_uca1400_swedish_as_ci
  * utf8mb4_uca1400_swedish_ai_cs
  * utf8mb4_uca1400_swedish_ai_ci

  and their _nopad_ variants:

  * utf8mb4_uca1400_swedish_nopad_as_cs
  * utf8mb4_uca1400_swedish_nopad_as_ci
  * utf8mb4_uca1400_swedish_nopad_ai_cs
  * utf8mb4_uca1400_swedish_nopad_ai_ci

- Introducing a conception of contextually typed named collations:

  CREATE DATABASE db1 CHARACTER SET utf8mb4;
  CREATE TABLE db1.t1 (a CHAR(10) COLLATE uca1400_as_ci);

  The idea is that there is no a need to specify the character set prefix
  in the new collation names. It's enough to type just the suffix
  "uca1400_as_ci". The character set is taken from the context.

  In the above example script the context character set is utf8mb4.
  So the CREATE TABLE will make a column with the collation
  utf8mb4_uca1400_as_ci.

  Short collations names can be used in any parts of the SQL syntax
  where the COLLATE clause is understood.

- New collations are displayed only one time
  (without character set combinations) by these statements:

     SELECT * FROM INFORMATION_SCHEMA.COLLATIONS;
     SHOW COLLATION;

  For example, all these collations:
  - utf8mb3_uca1400_swedish_as_ci
  - utf8mb4_uca1400_swedish_as_ci
  - ucs2_uca1400_swedish_as_ci
  - utf16_uca1400_swedish_as_ci
  - utf32_uca1400_swedish_as_ci
  have just one entry in INFORMATION_SCHEMA.COLLATIONS and SHOW COLLATION,
  with COLLATION_NAME equal to "uca1400_swedish_as_ci", which is the suffix
  without the character set name:

SELECT COLLATION_NAME FROM INFORMATION_SCHEMA.COLLATIONS
WHERE COLLATION_NAME LIKE '%uca1400_swedish_as_ci';

+-----------------------+
| COLLATION_NAME        |
+-----------------------+
| uca1400_swedish_as_ci |
+-----------------------+

  Note, the behaviour of old collations did not change.
  Non-unicode collations (e.g. latin1_swedish_ci) and
  old UCA-4.0.0 collations (e.g. utf8mb4_unicode_ci)
  are still displayed with the character set prefix, as before.

- The structure of the table INFORMATION_SCHEMA.COLLATIONS was changed.

  The NOT NULL constraint was removed from these columns:
  - CHARACTER_SET_NAME
  - ID
  - IS_DEFAULT
  and from the corresponding columns in SHOW COLLATION.

  For example:

SELECT COLLATION_NAME, CHARACTER_SET_NAME, ID, IS_DEFAULT
FROM INFORMATION_SCHEMA.COLLATIONS
WHERE COLLATION_NAME LIKE '%uca1400_swedish_as_ci';
+-----------------------+--------------------+------+------------+
| COLLATION_NAME        | CHARACTER_SET_NAME | ID   | IS_DEFAULT |
+-----------------------+--------------------+------+------------+
| uca1400_swedish_as_ci | NULL               | NULL | NULL       |
+-----------------------+--------------------+------+------------+

  The NULL value in these columns now means that the collation
  is applicable to multiple character sets.
  The behavioir of old collations did not change.
  Make sure your client programs can handle NULL values in these columns.

- The structure of the table
  INFORMATION_SCHEMA.COLLATION_CHARACTER_SET_APPLICABILITY was changed.

  Three new NOT NULL columns were added:
  - FULL_COLLATION_NAME
  - ID
  - IS_DEFAULT

  New collations have multiple entries in COLLATION_CHARACTER_SET_APPLICABILITY.
  The column COLLATION_NAME contains the collation name without the character
  set prefix. The column FULL_COLLATION_NAME contains the collation name with
  the character set prefix.

  Old collations have full collation name in both FULL_COLLATION_NAME and
  COLLATION_NAME.

SELECT COLLATION_NAME, FULL_COLLATION_NAME, CHARACTER_SET_NAME, ID, IS_DEFAULT
FROM INFORMATION_SCHEMA.COLLATION_CHARACTER_SET_APPLICABILITY
WHERE FULL_COLLATION_NAME RLIKE '^(utf8mb4|latin1).*swedish.*ci$';
+-----------------------------+-------------------------------------+--------------------+------+------------+
| COLLATION_NAME              | FULL_COLLATION_NAME                 | CHARACTER_SET_NAME | ID   | IS_DEFAULT |
+-----------------------------+-------------------------------------+--------------------+------+------------+
| latin1_swedish_ci           | latin1_swedish_ci                   | latin1             |    8 | Yes        |
| latin1_swedish_nopad_ci     | latin1_swedish_nopad_ci             | latin1             | 1032 |            |
| utf8mb4_swedish_ci          | utf8mb4_swedish_ci                  | utf8mb4            |  232 |            |
| uca1400_swedish_ai_ci       | utf8mb4_uca1400_swedish_ai_ci       | utf8mb4            | 2368 |            |
| uca1400_swedish_as_ci       | utf8mb4_uca1400_swedish_as_ci       | utf8mb4            | 2370 |            |
| uca1400_swedish_nopad_ai_ci | utf8mb4_uca1400_swedish_nopad_ai_ci | utf8mb4            | 2372 |            |
| uca1400_swedish_nopad_as_ci | utf8mb4_uca1400_swedish_nopad_as_ci | utf8mb4            | 2374 |            |
+-----------------------------+-------------------------------------+--------------------+------+------------+

- Other INFORMATION_SCHEMA queries:

  SELECT COLLATION_NAME FROM INFORMATION_SCHEMA.COLUMNS;
  SELECT COLLATION_NAME FROM INFORMATION_SCHEMA.PARAMETERS;
  SELECT TABLE_COLLATION FROM INFORMATION_SCHEMA.TABLES;
  SELECT DEFAULT_COLLATION_NAME FROM INFORMATION_SCHEMA.SCHEMATA;
  SELECT COLLATION_NAME FROM INFORMATION_SCHEMA.ROUTINES;
  SELECT COLLATION_CONNECTION FROM INFORMATION_SCHEMA.EVENTS;
  SELECT DATABASE_COLLATION FROM INFORMATION_SCHEMA.EVENTS;
  SELECT COLLATION_CONNECTION FROM INFORMATION_SCHEMA.ROUTINES;
  SELECT DATABASE_COLLATION FROM INFORMATION_SCHEMA.ROUTINES;
  SELECT COLLATION_CONNECTION FROM INFORMATION_SCHEMA.TRIGGERS;
  SELECT DATABASE_COLLATION FROM INFORMATION_SCHEMA.TRIGGERS;
  SELECT COLLATION_CONNECTION FROM INFORMATION_SCHEMA.VIEWS;

  display full collation names, including character sets prefix,
  for all collations, including new collations.

  Corresponding SHOW commands also display full collation names
  in collation related columns:

  SHOW CREATE TABLE t1;
  SHOW CREATE DATABASE db1;
  SHOW TABLE STATUS;
  SHOW CREATE FUNCTION f1;
  SHOW CREATE PROCEDURE p1;
  SHOW CREATE EVENT ev1;
  SHOW CREATE TRIGGER tr1;
  SHOW CREATE VIEW;

  These INFORMATION_SCHEMA queries and SHOW statements may change in
  the future, to display show collation names.

In addition, it sorts 'ch' between 'h' and 'i', and the sorting
is case sensitive, with uppercase being sorted first, in the
second pass.
