Problem: The Table_type column of "SHOW FULL TABLES" displayed
"ERROR" instead of "BASE TABLE" for tables having non-ascii
characters in their names.
Reason: tablename to filename encoding was missing, so
mysql_frm_type() tried to open a wrong file name.

Fix: adding tablename to filename encoding


mysql-test/r/show_check.result:
  Adding test case
mysql-test/t/show_check.test:
  Adding test case
sql/sql_show.cc:
  Adding tablename to filename encoding.
  Removing variable "end" with is not used anymore.
