Major Description
THD::reset_for_reuse() is missing clear of rli_fake and rgi_fake. Then the THD can be re-used for a new connection where these incorrectly remains set to left-overs from a previous connection.
Test case:
--connect(con1,localhost,root,,)

# The bug was that the THD::rli_fake was not cleared when the THD is re-used
|
# for the new connection, and we would get a warning from the following
|
# statement.

SET SESSION pseudo_slave_mode= 1;
|
--disconnect con1

This has occasionally been observed as random failure of test case sys_vars.character_set_results_basic, depending on what tests ran before it.
