This is because it breaks code that is using extern "C" when including
my_atomic, which is the case with ha_s3.cc

In the merge 9e6e43551fc61bc34152f8d60f5d72f0d3814787
we made Atomic_counter a more generic wrapper of std::atomic
so that dict_index_t would support the implicit assignment operator.
It is better to revert the changes to Atomic_counter and
instead introduce Atomic_relaxed as a generic wrapper to std::atomic.
Unlike Atomic_counter, we will not define operator++, operator+=
or similar, because we want to make the operations more explicit
in the users of Atomic_wrapper, because unlike loads and stores,
atomic read-modify-write operations always incur some overhead.

We will expose some more std::atomic internals in Atomic_counter,
so that dict_index_t::lock will support the default assignment operator.

When neither MSAN nor Valgrind are enabled, declare
Field::mark_unused_memory_as_defined() as an empty inline function,
instead of declaring it as a virtual function.

MDEV-22073 MSAN use-of-uninitialized-value in
collect_statistics_for_table()
Other things:
innodb.analyze_table was changed to mainly test statistic
collection. Was discussed with Marko.

Fix WolfSSL build:
- Do not build with TLSv1.0,it stopped working,at least with SChannel client
- Disable a test that depends on TLSv1.0
- define FP_MAX_BITS always, to fix 32bit builds.
- Increase MAX_AES_CTX_SIZE, to fix build on Linux

Rowid Filter check is just like Index Condition Pushdown check: before
we check the filter, we must check if we have walked out of the range
we are scanning. (If we did, we should return, and not continue the scan).
Consequences of this:
- Rowid filtering doesn't work for keys that have partially-covered
blob columns (just like Index Condition Pushdown)
- The rowid filter function has three return values: CHECK_POS (passed)
CHECK_NEG (filtered out), CHECK_OUT_OF_RANGE.
All of the above is implemented in this patch

my_wc_to_printable_generic on 10.5.2 (debug)
The code did not take into account that:
- U+005C (backslash) can occupy more than mbminlen characters (e.g. in sjis)
- Some character sets do not have a code for U+005C (e.g. swe7)
Adding a new function my_wc_to_printable into MY_CHARSET_HANDLER to
cover all special cases easier.

queues.c cleanup and refactoring.
Restore old version of _downhead() (from before cd483c55209)
that works well in an average case. Use it for queue_fix().
Move existing specialized version of _downhead() to queue_replace()
where it'll be handling the case it was specifically optimized for
(moving the element to the end of the queue).
And correct it to fix the heap not only down, but also up
(this fixes BUG#30301356).
Add unit tests.
Collateral cosmetic fixes.

This is a way do disable DBUG_ENTER()/DBUG_EXIT() stuff which is
needed to dbug trace. Those who doesn't need it may avoid tests
slowdown with -DWITH_DBUG_TRACE=OFF
dbug/tests.c: add define which is neede always in this test
innodb.log_file_name_debug.test: do not depend on DBUG trace stuff
in test
Benchmark results: each test eats less CPU and you can have more
parallel jobs in MTR.

KEY_MULTI_RANGE::range_flag does not have correct flag bits for
per-endpoint flags (NEAR_MIN, NEAR_MAX, NO_MIN_RANGE, NO_MAX_RANGE).
It only has bits for flags that describe both endpoints.
So
- Document this.
- Switch optimizer trace to using {start|end}_key.flag values, instead.
This fixes the bug.
- Switch records_in_column_ranges() to doing that too. (This used to
work, because KEY_MULTI_RANGE::range_flag had correct flag value
for the last key component, and EITS only uses one-component
pseudo-indexes)

The reason why we have wsrep_on() at all is that the macro WSREP(thd)
depends on the definition of THD, and that is intentionally an opaque
data type for InnoDB. So, we cannot avoid invoking wsrep_on(), but
we can evaluate the less expensive conditions thd && WSREP_ON before
calling the function.
Global_read_lock: Use WSREP_NNULL(thd) instead of wsrep_on(thd)
because we not only know the definition of THD but also that
the pointer is not null.
wsrep_open(): Use WSREP(thd) instead of wsrep_on(thd).
InnoDB: Replace thd && wsrep_on(thd) with wsrep_on(thd), now that
the condition has been merged to the definition of the macro
wsrep_on().

If the server is compiled WITH_WSREP=OFF, we should avoid evaluating
conditions on a global variable that is constant.
WSREP_ON_: Renamed from WSREP_ON. Defined only WITH_WSREP=ON.
WSREP_ON: Defined as unlikely(WSREP_ON_).
wsrep_on(): Defined as WSREP_ON && wsrep_service->wsrep_on_func().

Stop linking plugins to the server executable on Windows.
Instead, extract whole server functionality into a large DLL, called
server.dll. Link both plugins, and small server "stub" exe to it.
This eliminates plugin dependency on the name of the server executable.
It also reduces the size of the packages (since tiny mysqld.exe
and mariadbd.exe are now both linked to one big DLL)
Also, simplify the functionality of exporing all symbols from selected
static libraries. Rely on WINDOWS_EXPORT_ALL_SYMBOLS, rather than old
self-backed solution.
fix compile error
replace GetProcAddress(GetModuleHandle(NULL), "variable_name")
for server exported data with actual variable names.
Runtime loading was never required,was error prone
, since symbols could be missing at runtime, and now it actually failed,
because we do not export symbols from executable anymore, but from a shared
library
This did require a MYSQL_PLUGIN_IMPORT decoration for the plugin,
but made the code more straightforward, and avoids missing symbols at
runtime (as mentioned before).
The audit plugin is still doing some dynamic loading, as it aims to work
cross-version. Now it won't work cross-version on Windows, as it already
uses some symbols that are *not* dynamically loaded, e.g fn_format
and those symbols now exported from server.dll , when earlier they were
exported by mysqld.exe
Windows, fixes for storage engine plugin loading
after various rebranding stuff
Create server.dll containing functionality of the whole server
make mariadbd.exe/mysqld.exe a stub that is only calling mysqld_main()
