Currently, there are some useless includes in the codebase. We can use a tool named include-what-you-use to optimize these includes. By using a strict include-what-you-use policy, we can get lots of benefits from it.
when show databases/tables/table status where xxx, it will change a selectStmt to select result from
information_schema, it need catalog info to scan schema table, otherwise may get many
database or table info from multi catalog.
for example
mysql> show databases where schema_name='test';
+----------+
| Database |
+----------+
| test |
| test |
+----------+
MySQL [internal.test]> show tables from test where table_name='test_dc';

| test_dc |
| test_dc |

1. replace all boost::shared_ptr to std::shared_ptr
2. replace all boost::scopted_ptr to std::unique_ptr
3. replace all boost::scoped_array to std::unique<T[]>
4. replace all boost:thread to std::thread
