MDEV-37951 SHOW TABLES allows users with only GRANT OPTION privilege to read all table names in the database "mysql"

WITH GRANT OPTION is not a privilege in the standard sense,
so whenever INFORMATION_SCHEMA visibility dictates "any privilege"
this does not include WITH GRANT OPTION, even though GRANT_ACL
is a privilege in MariaDB.

MDEV-39318 some MTR tests fail with --ssl

* many test expected error 2013 (CR_SERVER_LOST)
  they should also expect 2026 (CR_SSL_CONNECTION_ERROR)
* some test --connect and expect a specific pre-auth error,
  they should use NOSSL option
* some tests start with invalid certificate - they work because
  mariadb-test doesn't connect with ssl by default. With --ssl
  it does and simply cannot connect. These tests use include/not_ssl.inc
* ssl_cipher restarts the server internally with invalid cipher.
  it should reconnect the default connection without SSL, otherwise
  mariadb-test will fail to connect after server is restarted
* tests that print ssl status without forcing it first - shouldn't,
  they don't know whether ssl is enabled or not.
* some perfschema tests are socket-specific and use include/not_ssl.inc
* perfschema status tables had too small column for ssl_ciphers value.

MDEV-36147 MariaDB cannot open page-compressed InnoDB tables at startup if innodb_compression_algorithm other than zlib is specified

When innodb_compression_algorithm is set to a non-zlib algorithm (e.g.
lz4) and the provider plugin is loaded from mysql.plugin rather than
command line, InnoDB failed to start because it checked for the provider
at plugin initialization time, before plugin_load() reads mysql.plugin.

Fix:
* InnoDB returns HA_ERR_RETRY_INIT when the compression provider is
  missing.
* In sql_plugin.cc, the retry loop is changed to not reap until
  mysql.plugin has been loaded

the fix is complex, and we keep this failing test around hurting all
other devs. The fix is planned, once finished, we can re-enable this

MDEV-37840 Server crashes when executing FLUSH PRIVILEGES after starting with skip-grant-tables and creating mysql.host table

hash_filo's mutex was lazily initialized in clear(), but grant_reload()
locks acl_cache->lock without first calling clear(). With
--skip-grant-tables, acl_cache is created but clear() is never called
(acl_reload() skips it on error), leaving the mutex uninitialized.

Fix: initialize the mutex eagerly in the hash_filo constructor and
remove the now-redundant init flag.

MDEV-24598 Duplicate CHECK constraint names are allowed

Field CHECK constraints always have the name of the corresponding field.
Table-level CHECK constraint can be arbitrary named and can have
the name of the field with a CHECK constraint.

Detect this and throw ER_DUP_CONSTRAINT_NAME.

Special treatment for auto-generated constraint names
(CONSTRAINT_1, etc) they can match a field name too - this is not
an error, just auto-generate a different name.

MDEV-28743 Roles without grants are handled wrong

In propagate_role_grants_action() (called by grant_reload() on startup
and FLUSH PRIVILEGES), role privilege merging uses a counter-based
bottom-up ordering: each role's counter tracks how many of its granted
sub-roles still need to be processed, and merge_role_privileges() merges
a role only once its counter reaches zero.

The bug: when an intermediate role such as org_role_1 (which inherits
only from a USAGE-only app_role_1) was merged with no privilege changes,
merge_role_privileges() returned 1 as an optimisation to stop upward
traversal.  This prevented the traversal from ever reaching user_role_1
to decrement its counter.  A second leaf traversal (from app_role_2)
could decrement user_role_1's counter only once, leaving it at 1
instead of 0, so user_role_1 was never merged and had no effective
privileges.

The "stop if nothing changed" optimisation is valid for incremental
propagate_role_grants() calls (after a single GRANT/REVOKE), where
every ancestor was already correctly merged.  It is not valid for the
full-reload case, where the counters must be decremented by every leaf
traversal to guarantee correct bottom-up ordering.

Fix: add an initial_load flag to PRIVS_TO_MERGE.  When set (only in
propagate_role_grants_action), the early-stop optimisation is disabled
so traversals always visit all ancestors.

squash! 6e3fd9cbbca55c18f29a62850d0add915dbc71b5

Replace the Master_info::using_gtid pointer with accessor functions.

Master_info kept a pointer into Master_use_gtid_value::active_mode and
all readers accessed the current gtid mode through using_gtid[0]. The
pointer member added an indirection on every check and hid where the
value actually lives. Master_info_file now provides two inline
functions instead, both going directly to the member:

* using_gtid() returns the current mode, for the code that needs the
  value itself (SHOW SLAVE STATUS and performance schema output,
  comparisons against CURRENT_POS and SLAVE_POS).
* is_gtid_supported() tells whether the connection uses gtid at all.
  The many callers that compared the mode against USE_GTID_NO with ==
  or != now call this function instead of testing the enum value.

Master_use_gtid_value::supported() did the same test as
is_gtid_supported() and is removed; its only caller now uses the new
function. The conversion of the call sites is mechanical and there is
no change in behavior.
