An attempt to open file with name '????????.frm'
can produce different errors:
- ER_NO_SUCH_TABLE on Unix
- ER_FILE_NOT_FOUND on Windows
because QUESTION MARK has special meaning on Windows.
Make sure that any of these two errors happens.

  Problem: Temporary buffer which is used for quoting and escaping
  was initialized to character set utf8, and thus didn't allow
  to store data in other character sets.
  Fix: changing character set of the buffer to be able to
  store any arbitrary sequence of bytes.

  Problem: crash on attempt to open a table
  having "#mysql50#" prefix in db or table name.
  Fix: This prefix is reserved for "mysql_upgrade"
  to access 5.0 tables  whose file names are not encoded
  according to "5.1 tablename to filename encoded".
  Don't try open tables whose db name or table name
  has this prefix.

            SHOW CREATE TABLE fails
Addition to the fix: report db name + table name instead of table path.
This solves embedded merge test failure.

  "Embedded server requires mysql.plugin"
  Embedded builds should not print any error when the mysql.plugin
  table does not exist. This is achieved by checking for the existance
  of the mysql.plugin table before attempting to open it and proceed
  silently if it does not exist.

  Add another exception to the acceptable mysqld errors, for test case for bug 28436

            SHOW CREATE TABLE fails

Underlying table names, that merge engine fails to open were not
reported.

With this fix CHECK TABLE issued against merge table reports all
underlying table names that it fails to open. Other statements
are unaffected, that is underlying table names are not included
into error message.

This fix doesn't solve SHOW CREATE TABLE issue.
