Post-merge fixes: Remove the MYSQL_VERSION_ID checks, because they only
apply to the InnoDB Plugin. Fix potential race condition accessing
trx->op_info and trx->detailed_error.

message:
  Make the InnoDB FOREIGN KEY parser understand multi-statements. (Bug #48024)
  Also make InnoDB thinks that /*/ only starts a comment. (Bug #53644).

  This fixes the bugs in the InnoDB Plugin.

  ha_innodb.h: Use trx_query_string() instead of trx_query() when
  available (MySQL 5.1.42 or later).

  innobase_get_stmt(): New function, to retrieve the currently running
  SQL statement.

  struct trx_struct: Remove mysql_query_str. Use innobase_get_stmt() instead.

  dict_strip_comments(): Add and observe the parameter sql_length. Treat
  /*/ as the start of a comment.

  dict_create_foreign_constraints(), row_table_add_foreign_constraints():
  Add the parameter sql_length.
