Rewriting GRANT/REVOKE grammar to use more bison stack and use Sql_cmd_ style
1. Removing a few members from LEX:
- uint grant, grant_to_col, which_columns
- List<LEX_COLUMN> columns
- bool all_privileges
2. Adding classes Grand_object_name, Lex_grant_object_name
3. Adding classes Grand_privilege, Lex_grand_privilege
4. Adding struct Lex_column_list_privilege_st, class Lex_column_list_privilege
5. Rewriting the GRANT/REVOKE grammar to use new classes and pass them through
bison stack (rather than directly access LEX members)
6. Adding classes Sql_cmd_grant* and Sql_cmd_revoke*,
changing GRANT/REVOKE to use LEX::m_sql_cmd.
7. Adding the "sp_handler" grammar rule and removing some duplicate grammar
for GRANT/REVOKE for different kinds of SP objects.
8. Adding a new rule comma_separated_ident_list, reusing it in:
- with_column_list
- colum_list_privilege
- Any temporary tables created under read-only mode will never be logged
to binary log. Any usage of these tables to update normal tables, even
after read-only has been disabled, will use row base logging (as the
temporary table will not be on the slave).
- Analyze, check and repair table will not be logged in read-only mode.
Other things:
- Removed not used varaibles in
MYSQL_BIN_LOG::flush_and_set_pending_rows_event.
- Set table_share->table_creation_was_logged for all normal tables.
- THD::binlog_query() now returns -1 if statement was not logged., This
is used to update table_share->table_creation_was_logged.
- Don't log admin statements in opt_readonly is set.
- Table's that doesn't have table_creation_was_logged will set binlog format to row
logging.
- Removed not needed/wrong setting of table->s->table_creation_was_logged
in create_table_from_items()
- Initialize variables that could be used uninitialized
- Added extra end space to DbugStringItemTypeValue to get rid of warnings
from c_ptr()
- Session_sysvars_tracker::update() accessed unitialized memory if called
with NULL value.
- get_schema_stat_record() accessed unitialized memory if HA_KEY_LONG_HASH
was used
- parse_vcol_defs() accessed random memory for tables without keys.
* wait() for the child process to die, let it rest in peace
* fix incorrect parentheses
* if there was no password on the command line or in .cnf file,
pkt will be "", and we need to request the user to enter the password
* make sure that auth->salt is always allocated on a permanent memroot.
when called from set_user_salt_if_needed(), user_copy and its auth_str
are on the thd memroot, but auth_copy->salt is then copied to auth->salt
* adjust service files so that systemd wouldn't interfere with our
setuid executables
also
* print the pam error message in debug mode

Maintainer mode makes all warnings errors. This patch fix warnings. Mostly about
deprecated `register` keyword.
Too much warnings came from Mroonga and I gave up on it.
fixes
MDEV-14732 mysql.db privileges evaluated on order of grants rather than hierarchically
MDEV-8269 Correct fix for Bug #20181776 :- ACCESS CONTROL DOESN'T MATCH MOST SPECIFIC HOST WHEN IT CONTAINS WILDCARD
reimplement the old ad hoc get_sort() function to use a wildcard
pattern ordering logic that works correctly in may be all practical cases.
get_sort() is renamed to catch merge errors at compilation time.
moved to a separate included file, because of a long comment.
Removed LOCK_connection_count.
Removed duplicate denied_connections and connection_errors_max_connection
increment from create_new_thread(). Another increment done by
CONNECT::close_with_error().
Simplified away CONNECT::thread_count_incremented. Now close_with_error()
is always called with connection_count incremented.
