5392b4a32c MDEV-20354 All but last insert ignored in InnoDB tables when table locked
mysql_insert() first opens all affected tables (which implicitly
starts a transaction in InnoDB), then stat tables.
A failure to open a stat table caused open_tables() to abort
the current stmt transaction (trans_rollback_stmt()). So, from the
server point of view the following ha_write_row()-s happened outside
of a transactions, and the server didn't bother to commit them.

The server has a mechanism to prevent a transaction being
unexpectedly committed or rolled back in the middle of a statement -
if an operation takes place _in a sub-statement_ it cannot change
the transaction state. Operations on stat tables are exactly that -
they are not allowed to change a transaction state. Put them in
a sub-statement to make sure they don't.

adefaeffcc MDEV-19536 - Server crash or ASAN heap-use-after-free in is_temporary_table /
read_statistics_for_tables_if_needed

Regression after 279a907, read_statistics_for_tables_if_needed() was
called after open_normal_and_derived_tables() failure.

Fixed by moving read_statistics_for_tables() call to a branch of
get_schema_stat_record() where result of open_normal_and_derived_tables()
is checked.

Removed THD::force_read_stats, added read_statistics_for_tables() instead.
Simplified away statistics_for_command_is_needed().

588e67956a Make sure histograms do not write uninitialized bytes to record
A histogram size that is odd in size with DOUBLE precision will leave the last
byte unwritten. When collecting histograms, this causes the last byte to
be uninitialized in the record. memset the buffer to 0 first to make
sure this does not happen.

279a907fd0 MDEV-17605 Statistics for InnoDB table is wrong if persistent statistics is used
The command SHOW INDEXES ignored setting of the system variable
use_stat_tables to the value of 'preferably' and and showed statistical
data received from the engine. Similarly queries over the table
STATISTICS from INFORMATION_SCHEMA ignored this setting. It happened
because the function fill_schema_table_by_open() did not read any data
from statistical tables.

409dddf695 MDEV-18300: ASAN error in Field_blob::get_key_image upon UPDATE with subquery
For single table updates and multi-table updates , engine independent statistics were not being
read even if the statistics were collected.
Fixed it, so when the optimizer_use_condition_selectivity > 2 then we would read the available
statistics for update queries.

621041b676 Merge 10.0 into 10.1
Also, apply the MDEV-17957 changes to encrypted page checksums,
and remove error message output from the checksum function,
because these messages would be useless noise when mariabackup
is retrying reads of corrupted-looking pages, and not that
useful during normal server operation either.

The error messages in fil_space_verify_crypt_checksum()
should be refactored separately.

4886d14827 MDEV-17032: Estimates are higher for partitions of a table with @@use_stat_tables= PREFERABLY
The problem here is EITS statistics does not calculate statistics for the partitions of the table.
So a temporary solution would be to not read EITS statistics for partitioned tables.

Also disabling reading of EITS for columns that participate in the partition list of a table.

095dc81158 MDEV-16757 Memory leak after adding manually min/max statistical data
for blob column

ANALYZE TABLE <table> does not collect statistical data on min/max values
for BLOB columns of <table>. However these values can be added into
mysql.column_stats manually by executing proper statements.
Unfortunately this led to a memory leak because the memory allocated
for these values was never freed.
This patch provides the server with a function to free memory allocated
for min/max statistical values of BLOB types.

Temporarily changed the test case until MDEV-16711 is fixed as without
this fix the test case for MDEV-16757 did not fail only for 10.0.

10f6b7001b MDEV-9744: session optimizer_use_condition_selectivity=5 causing SQL Error (1918):
Encountered illegal value '' when converting to DECIMAL

The issue was that EITS data was allocated but then not read for some reason (one being to avoid a deadlock),
then the optimizer was using these bzero'ed buffers as EITS statistics.
This should not be allowed, we should use statistcs for a table only when we have successfully loaded/read
the stats from the statistical tables.

f91798dd1c MDEV-7370: Server deadlocks on renaming a table for which persistent statistics exists
RENAME TABLE code tries to update EITS statistics. It hung, because
it used an index on (db_name,table_name) to find the table, and attempted
to update these values at the same time. The fix is do what SQL UPDATE
statement does when updating index that it's used for scanning:
- First, buffer the rowids of rows to be updated,
- then make the second pass to actually update the rows

Also fixed the call to rename_table_in_stat_tables() in sql_rename.cc
to pass the correct new database (before, it passed old db_name so cross-
database renames were not handled correctly).

Variant #2, with review feedback addressed.

70823e1d91 MDEV-5120 Test suite test maria-no-logging fails
The reason for the failure was a bug in an include file on debian that causes 'struct stat'
to have different sized depending on the environment.

This patch fixes so that we always include my_global.h or my_config.h before we include any other files.

Other things:
- Removed #include <my_global.h> in some include files; Better to always do this at the top level to have as few
  "always-include-this-file-first' files as possible.
- Removed usage of some include files that where already included by my_global.h or by other files.
