+  Create a table
+
+  SYNOPSIS
+    mysql_create_table()
+    thd			Thread object
+    db			Database
+    table_name		Table name
+    create_info		Create information (like MAX_ROWS)
+    fields		List of fields to create
+    keys		List of keys to create
+    tmp_table		Set to 1 if this is a temporary table
+    no_log		Don't log the query to binary log.
+
+  DESCRIPTION		       
+    If one creates a temporary table, this is automaticly opened
+
+    no_log is needed for the case of CREATE ... SELECT,
+    as the logging will be done later in sql_insert.cc
+    select_field_count is also used for CREATE ... SELECT,
+    and must be zero for standard create of table.

+  RETURN VALUES
+    0	ok
