This commit changes backup execution (namely the block ddl phase),
so that node is not paused from cluster. Instead, the following
backup execution is declared as vulnerable for possible cluster
level conflicts, especially with DDL statement applying.
With this, the mariabackup execution may be aborted, if DDL
statements happen during backup execution. This abortable
backup execution is optional feature and may be
enabled/disabled by wsrep_mode: BF_ABORT_MARIABACKUP.
Note that old style node desync and pause, despite of
WSREP_MODE_BF_MARIABACKUP is needed if node is operating as
SST donor.

Making changes to wsrep_mysqld.h causes large parts of server code to
be recompiled. The reason is that wsrep_mysqld.h is included by
sql_class.h, even tough very little of wsrep_mysqld.h is needed in
sql_class.h. This commit introduces a new header file, wsrep_on.h,
which is meant to be included from sql_class.h, and contains only
macros and variable declarations used to determine whether wsrep is
enabled.
Also, header wsrep.h should only contain definitions that are also
used outside of sql/. Therefore, move WSREP_TO_ISOLATION* and
WSREP_SYNC_WAIT macros to wsrep_mysqld.h.

... on semisync slave
To provide semisync master crash-recovery the same server-id transactions
were made to accept for execution on the semisync slave when the strict gtid
mode (see MDEV-27760).
That however caused out-of-order error on a master's transaction
server of the circular setup.
The error was fair in the sense of the gtid strict mode rule as indeed
under the condition of the circular setup the replicated transaction
already exists in the local binlog.
This is fixed by the commit to ignore on the gtid strict mode semisync
slave those gtids that exist in the slave's binlog that effectively restores
the default same-server-id ignore policy.
At the same time the fixes complies with MDEV-21117 semisync slave recovery
to accept the same server-id transactions that do not exist in local binlog.

commit '6de482a6fefac0c21daf33ed465644151cdf879f'
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.

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