MDEV-33729 UBSAN negation of -X cannot be represented in type 'long long int'; cast to an unsigned type to negate this value to itself in my_strntoll_mb2_or_mb4

The problem was introduced by MDEV-30879.
The function my_strntoll_8bit() was correctly changed by MDEV-30879.
The function my_strntoll_mb2_or_mb4() was not.

Applying the missing change to my_strntoll_mb2_or_mb4().

This bug was found related to MDEV-34212.

Some InnoDB tests, most notably innodb.table_flags,64k would occasionally
fail. I am able to reproduce this locally on a MemorySanitizer build,
sporadically.

The following is a minimal .test file for reproducing this:
  --source include/have_innodb.inc
  SELECT @@innodb_page_size;
and the .opt file:
  --innodb-undo-tablespaces=0 --innodb-page-size=64k
  --innodb-buffer-pool-size=20m

This bug was revealed due to the recent
commit 466ae1cf
which set innodb_fast_shutdown=0 during server bootstrap
in our regression test driver.

Due to the bug, a write of undo page 50 in the system tablespace
was discarded in buf_page_t::flush(). A subsequent InnoDB startup
failed because an old version of that page would point to a
freed undo log page 300.

mtr_t::commit_shrink(): Only invoke fil_space_t::set_create_lsn()
on undo tablespaces, which will be fully reinitialized or created
from the scratch. On the system tablespace, we must only adjust
the file size, to avoid writing pages that are beyond the end
of the tablespace. Thanks to Thirunarayanan Balathandayuthapani
for providing this fix.

innobase_end(): Do not attempt to shrink the system tablespace if
innodb_read_only=ON or innodb_force_recovery>4. This fixes a regression
due to commit 2d6c2f22 (MDEV-32452).

This bug was caught when testing a fix of MDEV-34200, which adds
SET GLOBAL innodb_fast_shutdown=0 to the test innodb.undo_upgrade.

C/C 3.4 disables mysql_old_password by default, so

add an option for the `connect` command to support specifying
allowed authentication plugins (MARIADB_OPT_RESTRICTED_AUTH).

use it to enable mysql_old_password when needed for testing

it no longer supports TLSv1.0

In the merge commit f9807aad
there were some omissions or errors.

ibuf_remove_free_page(): Return an error if the free list is corrupted
when removing the change buffer on an upgrade. A special 11.0 version of
commit 263932d5 would have been useful.

buf_page_get_gen(): Correctly handle the case that a page was being
concurrently read into the buffer pool and found out to be corrupted.
This was part of commit a4cda66e
but had been discarded in the merge.

Because MariaDB Server 11.0 has reached its end of life as of
commit 466ae1cf this fix is being applied
to the 11.1 branch.

Alternative operator name keywords like `and`, `or`, `xor`, etc., are
uncommon in MariaDB and can cause obscure build errors when the GCC
flag `-fno-operator-names` is applied.

Description of `-fno-operator-names`:
https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Dialect-Options.html
> Do not treat the operator name keywords `and`, `bitand`, `bitor`,
> `compl`, `not`, `or` and `xor` as synonyms as keywords.

Part of the build errors:

    /local/p4clients/pkgbuild-LdLa_/workspace/src/RDSMariaDB/sql/sql_select.cc:11171:28: error: expected ‘)’ before ‘and’
    11171 |     DBUG_ASSERT(sel >= 0.0 and sel <= 1.00001);
          |                            ^~~
    /local/p4clients/pkgbuild-LdLa_/workspace/src/RDSMariaDB/include/my_global.h:372:44: note: in definition of macro ‘unlikely’

          |                                            ^
    ...

The build failure is caused by using alternative operator name keywords
`and` introduced in commit b66cdbd1.
Replace the `and` keyword with `&&` and target on MariaDB 11.0+ branches
which include the commit.

disable view protocol (DROP VIEW doesn't work very well with transactions)
and cosmetic cleanups

(Based on original patch by Oleksandr Byelkin)

Multi-table DELETE can execute via "buffered" mode: at phase #1 it collects
rowids of rows to be deleted, then at phase #2 in multi_delete::do_deletes()
it calls handler->rnd_pos() to read rows to be deleted and deletes them.

The problem occurred when phase #1 used Rowid Filter on the table that
phase #2 would be deleting from.
In InnoDB, h->rnd_init(scan=false) and h->rnd_pos() is an index scan over PK
under the hood. So, at phase #2 ha_innobase::rnd_init() would try to use the
Rowid Filter and hit an assertion inside ha_innobase::rnd_init().

Note that multi-table UPDATE works similarly but was not affected, because
patch for MDEV-7487 added code to disable rowid filter for phase #2 in
multi_update::do_updates().

This patch changes the approach:
- It makes InnoDB not use Rowid Filter in rnd_pos() scans: it is disabled in
  ha_innobase::rnd_init() and enabled back in ha_innobase::rnd_end().
- multi_update::do_updates() no longer disables Rowid Filter for phase#2 as
  it is no longer necessary.

Workaround patch: Do not remove GROUP BY clause when it has
subquer(ies) in it.

remove_redundant_subquery_clauses() removes redundant GROUP BY clause
from queries in form:
  expr IN (SELECT no_aggregates GROUP BY ...)
  expr {CMP} {ALL|ANY|SOME} (SELECT no_aggregates GROUP BY ...)
This hits problems when the GROUP BY clause itself has subquer(y/ies).

This patch is just a workaround: it disables removal of GROUP BY clause
if the clause has one or more subqueries in it.

Tests:
- subselect_elimination.test has all known crashing cases.
- subselect4.result, insert_select.result are updated.
Note that in some cases results of SELECT are changed too (not just
EXPLAINs). These are caused by non-deterministic SQL: when running a
query like:

  x > ANY( SELECT col1 FROM t1 GROUP BY constant_expression)

without removing the GROUP BY, the executor is free to pick the value
of t1.col1 from any row in the GROUP BY group (denote it $COL1_VAL).
Then, it computes x > ANY(SELECT $COL1_VAL).

When running the same query and removing the GROUP BY:

   x > ANY( SELECT col1 FROM t1)

the executor will actually check all rows of t1.

The problem was two fold:
- REPAIR TABLE t1 USE_FRM did not work for transactional
  Aria tables (Table was thought to be repaired, which it was not) which
  caused issues in later usage of the table.
- When swapping tmp_data file to data file, sort_info files where not
  updated. This caused problems if there was several unique keys and
  there was a duplicate for the second key.

Due to this bug a wrong result might be expected from queries with
an IN subquery predicate in the WHERE clause and a derived table in the
FROM clause to which split optimization could be applied.

The function JOIN::fix_all_splittings_in_plan() used the value of the
bitmap JOIN::sjm_lookup_tables() such as it had been left after the
search for the best plan for the select containing the splittable
derived table. That value could not be guaranteed to be correct. So the
recalculation of this bitmap is needed to exclude the plans with key
accesses from SJM lookup tables.
