recv_addr_state, recv_addr_t: Define in log0recv.cc only.

Because innodb_file_per_table can be enabled at runtime after it
was disabled at startup, it is better to always register the same
innobase_hton->tablefile_extensions. Besides,
innodb_file_per_table=OFF does not prevent loading tables that may
have been created earlier with the .ibd file extension.

Remove plugin-load option from mariabackup. It does not needed to be an
option (we only need to store the plugin-load value during backup phase,
and reuse the same value during --prepare).

Fix is to read plugin-load from backup-my.cnf during prepare.

Fix exit condition for the log copying thread.

Also, disable /permissive- flag if set, it breaks rocksdb compilation
in 10.3 on older versions of Windows 8.1 SDK.

It uses --slave-use-idempotent-for-recovery which is not available in MariaDB.

Remove the mismatch betwen list of man pages in CMakeLists.txt and
actual files.

Direct IO doesnt work on all filesystems, e.g. it doesnt work on the
disk of kvm-bintar-trusty-amd64.

This regression was introduced in MDEV-16515.
We would fail to drop a temporary table on client disconnect,
because trx_is_interrupted() would hold. To add insult to
injury, in MariaDB 10.1, InnoDB temporary tables are actually
persistent, so the garbage temporary tables will never be dropped.

row_drop_table_for_mysql(): If several iterations of
buf_LRU_drop_page_hash_for_tablespace() are needed,
do not interrupt dropping a temporary table even after
the transaction was marked as killed.

Server shutdown will still terminate the loop, and also DROP TABLE
of persistent tables will keep checking if the execution was aborted.

This reverts commit 75dfd4ac.

Plugin version name fixed.

Let '\\' and '/' symbols to be part of a group name.

           Field_iterator_table_ref::set_field_iterator

Several functions that processed different prepare statements missed
the DT_INIT flag in last parameter of the open_normal_and_derived_tables()
calls. It made context analysis of derived tables dependent on the order in
which the derived tables were processed by mysql_handle_derived(). This
order was induced by the order of SELECTs in all_select_list.
In 10.4 the order of SELECTs in all_select_list became different and lack
of the DT_INIT flags in some open_normal_and_derived_tables() call became
critical as some derived tables were not identified as such.

Problem was that a parallel open of a table, overwrote info->state that
was in used by repair.

Fixed by changing _ma_tmp_disable_logging_for_table() to use
a new state buffer state.no_logging to store the temporary state.

Other things:
- Use original number of rows when retrying repair to get rid of a
  potential warning "Number of rows changed from X to Y"
- Changed maria_commit() to make it easier to merge with 10.4
- If table is not locked (like with show commands), use the global
  number of rows as the local number may not be up to date.
  (Minor not critical fix)
- Added some missing DBUG_RETURN
