extra2_read_len resolved by keeping the implementation
in sql/table.cc by exposed it for use by ha_partition.cc

10.3 no longer errors in truncate_notembedded.test
but per comments, a non-crash is all that we are after.
Fixed typo in my_malloc_size_cb_func. There is no max-thread-mem-used
sys variable in MariaDB, only max-session-mem-used. The relevant entry
in sys_vars.cc is also fixed.
Added a fallback case in case we could allocate the 256 bytes for the
error message containing the exact setting.
Variable `wsrep_new_cluster` now will be TRUE also when there is only `gcomm://` used
in configuration. This configuration, even without --wsrep-new-cluster,
is considered to bootstrap new cluster.
Updated galera GTID test to ignore warning message when non bootstrap
node have server-id different thant one cluster is initialized with.

For non bootstrap node server id should be ignored because using custom
value can lead to inconsistency problem with replicated GTID in cluster.
Providing warning message when this happens.

Locking / unlocking plugins is already handled by Sys_var_plugin::check
method. No need to do that in the specialized checking code, use
var->save_value instead to get the plugin handle.
The crash happened because my_isalnum() does not support character
sets with mbminlen>1.
The value of "ft_boolean_syntax" is converted to utf8 in do_string_check().
So calling my_isalnum() is combination with "default_charset_info" was wrong.
Adding new parameters (size_t length, CHARSET_INFO *cs) to
ft_boolean_check_syntax_string() and passing self->charset(thd)
as the character set.
This is important since Sys_var_typelib and its descendants return
pointers to constant symbols from *_value_ptr, which are situated in
write-protected-memory.
* functions const-qualified:
- value_ptr
- session_value_ptr
- global_value_ptr
- default_value_ptr
- Sys_var_vers_asof::value_ptr
- other minor private ones
* remove C-style typecasts when it discards qualifiers
MDEV-16026: Forbid global system_versioning_asof in non-default time zone
* store `system_versioning_asof` in unix time;
* both session and global vars are processed in session timezone;
* setting `default` does not copy global variable anymore. Instead, it sets
system_time to SYSTEM_TIME_UNSPECIFIED, which means that no 'AS OF' time
is applied and `now()` can be assumed
As a regression, we cannot assign values below 1970 (UTC) anymore
MDEV-16481: set global system_versioning_asof=sf() crashes in specific case
* sys_vars.h: add `MYSQL_TIME` field to `set_var::save_result`
* sys_vars.ic: get rid of calling `var->value->get_date()` from
`Sys_var_vers_asof::update()`
* versioning.sysvars: add test; remove double warning
refactor Sys_var_vers_asof
* inherit from sys_var rather than Sys_var_enum
* remove junk "DEFAULT" keyword. There is DEFAULT in SQL grammar for it.
* make all conversions in check() to avoid possible errors
* avoid double var->value evaluation, which could
consequence in undefined behavior
- There should be no substitution if engine exists, only when doesn't
exist
- Handling of an error when sys_var `default_tmp_storage_engine` is
assigned to unsupported engine.
- rocksdb doesn't support embedded server ebfc4e6ad0 so is excluded

This fixed the MySQL bug# 20338 about misuse of double underscore
prefix __WIN__, which was old MySQL's idea of identifying Windows
Replace it by _WIN32 standard symbol for targeting Windows OS
(both 32 and 64 bit)
Not that connect storage engine is not fixed in this patch (must be
fixed in "upstream" branch)
This change removed 68 explict strlen() calls from the code.
The following renames was done to ensure we don't use the old names
when merging code from earlier releases, as using the new variables
for print function could result in crashes:
- charset->csname renamed to charset->cs_name
- charset->name renamed to charset->coll_name
Almost everything where mechanical changes except:
- Changed to use the new Protocol::store(LEX_CSTRING..) when possible
- Changed to use field->store(LEX_CSTRING*, CHARSET_INFO*) when possible
- Changed to use String->append(LEX_CSTRING&) when possible
Other things:
- There where compiler issues with ensuring that all character set names
points to the same string: gcc doesn't allow one to use integer constants
when defining global structures (constant char * pointers works fine).
To get around this, I declared defines for each character set name
length.
This patch changes the main name of 3 byte character set from utf8 to
utf8mb3. New old_mode UTF8_IS_UTF8MB3 is added and set TRUE by default,
so that utf8 would mean utf8mb3. If not set, utf8 would mean utf8mb4.

Note:
From the upstream patch only the new option binlog_expire_logs_seconds
specific changes are taken.
* Unlike in the upstream patch 'binlog_expire_logs_seconds' does not
replace the "old" 'expire_logs_days', to preserve backward-compatibility.
* Datatype of 'expire_logs_days' variable is changed to double.
* Default value of 'binlog_expire_logs_seconds=0' similar to
'expire_logs_days'.
* The purge_time can be specified in days with the micro-day precision.
Eg:
expire_logs_days=1 is the same as expire_logs_days=1.000000 to make
binlog_expire_logs_seconds=86400.
binlog_expire_logs_seconds=1 is the same as expire_logs_days=0.000012.
* If binary log is disabled and option 'expire_logs_days' or
'binlog_expire_logs_seconds' used with purge_time > 0 a warning will be
issued.
