- Original patch was contributed by Jani Tolonen <jani.k.tolonen@gmail.com>
https://github.com/an3l/server/commits/bb-10.3-anel-MDEV-21786-dump-sequence
which distinguishes data structure (linked list) of sequences from
tables.
- Added standard sql output to prevent future changes
of sequences and disabled locks for sequences.
- Added test case for `MDEV-20070: mysqldump won't work correct on
sequences` where table column depends on sequence value.
- Restore sequence last value in the following way:
- Find `next_not_cached_value` and use it to `setval()`
- We just need for logical restore, so don't execute `setval()`
- `setval()` should be showed also in case of `--no-data` option.

When including a generated file, always use <...>.
We need the compiler to find it in the BINDIR, not in the SRCDIR.
But when including as "..." SRCDIR is always searched first.
The bug can only happen in out-of-source builds, if there was an
in-source build before.
It is already in libmariadb, and server (also that client in server)
does not need it.
It does not work in embedded either since it relies on non-blocking sockets

In case of a pattern of non-STMT_END-marked Rows-log-event (A) followed by
a STMT_END marked one (B) mysqlbinlog mixes up the base64 encoded rows events
with their pseudo sql representation produced by the verbose option:
BINLOG '
base64 encoded data for A
### verbose section for A
base64 encoded data for B
### verbose section for B
'/*!*/;
In effect the produced BINLOG '...' query is not valid and is rejected with the error.
Examples of this way malformed BINLOG could have been found in binlog_row_annotate.result
that gets corrected with the patch.
The issue is fixed with introduction an auxiliary IO_CACHE to hold on the verbose
comments until the terminal STMT_END event is found. The new cache is emptied
out after two pre-existing ones are done at that time.
The correctly produced output now for the above case is as the following:
BINLOG '
base64 encoded data for A
base64 encoded data for B
'/*!*/;
### verbose section for A
### verbose section for B
Thanks to Alexey Midenkov for the problem recognition and attempt to tackle,
Venkatesh Duggirala who produced a patch for the upstream whose
idea is exploited here, as well as to MDEV-23077 reporter LukeXwang who
also contributed a piece of a patch aiming at this issue.
Extra: mysqlbinlog_row_minimal refined to not produce mutable numeric values into the result file.

Shutdown of mtr tests may be too impatient, esp on CI environment where
10 seconds of `arg` of `shutdown_server arg` may not be enough for the clean
shutdown to complete.
This is fixed to remove explicit non-zero timeout argument to
`shutdown_server` from all mtr tests. mysqltest computes 60 seconds default
value for the timeout for the argless `shutdown_server` command.
This policy is additionally ensured with a compile time assert.
- Some of the bug fixes are backports from 10.5!
- The fix in innobase/fil/fil0fil.cc is just a backport to get less
error messages in mysqld.1.err when running with valgrind.
- Renamed HAVE_valgrind_or_MSAN to HAVE_valgrind
