Description

A search git grep 'SHOW_VAR.*char' reveals many functions that do not match the signature of mysql_show_var_func but are registered as function callbacks.

These should be fixed, to avoid errors like this:

10.4 832e96deb6f368591dcb35a4fa33b2fd770aa17a

/mariadb/10.4/sql/sql_show.cc:3843:7: runtime error: call to function show_memory_used(THD*, st_mysql_show_var*, char*, system_status_var*, enum_var_type) through pointer to incorrect function type 'int (*)(THD *, st_mysql_show_var *, void *, system_status_var *, enum_var_type)'

/mariadb/10.4/sql/mysqld.cc:7612: note: show_memory_used(THD*, st_mysql_show_var*, char*, system_status_var*, enum_var_type) defined here

Some of these functions are defined with a mismatching number of parameters as well.
