bb47050e1f MDEV-22640, MDEV-22449, MDEV-21528 JSON_ARRAYAGG crashes with NULL values.
We have to include NULL in the result which the GOUP_CONCAT doesn't
always do. Also converting should be done into another String instance
as these can be same.

d49233caf6 MDEV-18100: User defined aggregate functions not working correctly when the schema is changed
The issue here was that when the schema was changed the value for the THD::server_status
is ored with SERVER_SESSION_STATE_CHANGED.
For custom aggregate functions, currently we check if the server_status is equal to
SERVER_STATUS_LAST_ROW_SENT then we should terminate the execution of the custom
aggregate function as there are no more rows to fetch.
So the check should be that if the server status has the bit set for
SERVER_STATUS_LAST_ROW_SENT then we should terminate the execution of the
custom aggregate function.

cd41ffe1f1 MDEV-19713 Remove big_tables system variable
mark big_tables deprecated, the server can put temp tables on disk
as needed avoiding "table full" errors.

in case someone would really need to force a tmp table to be created
on disk from the start and for testing allow tmp_memory_table_size
to be set to 0.

fix tests to use that instead (and add a test that it actually
works).

make sure in-memory TREE size limit is never 0 (it's [ab]using
tmp_memory_table_size at the moment)

remove few sys_vars.*_basic tests

afe6eb499d Revert "MDEV-20342 Turn Field::flags from a member to a method"
This reverts commit e86010f909.

Reverting on Monty's request, as this change makes merging
things from 10.5 to 10.2 much harder.

MDEV-16620: Add JSON_ARRAYAGG function
The JSON_ARRAYAGG function extends the GROUP_CONCAT function and provides
a method of aggregating JSON results. The current implementation supports
DISTINCT and LIMIT but not ORDER BY (Oracle supports GROUP BY).

Adding GROUP BY support is possible but it requires some extra work as the
grouping appears to be done inside a temporary table that complicates
matters.

Added test cases that covert aggregation of all JSON types and JSON
validation for the generated results.

979cad2291 MDEV-9531 GROUP_CONCAT with ORDER BY inside takes a lot of memory while it's executed
group concat tree is allocated in a memroot, so the only way to free
memory is to copy a part of the tree into a new memroot.

track the accumilated length of the result, and when it crosses
the threshold  - copy the result into a new tree, free the old one.
