dumpTables currently badly handles BLOB and TEXT data containing control
characters:
* MySQL will interpret and unescape string literals e.g.`\r` will become
carriage return.
* Postgres will not allow string literals to contain NUL nor will
SQLite so BLOBs will not dump correctly.
* Schemas should not be set on the destination dump
* MSSQL needs the N prefix to correctly ensure that UTF-8 data is
correctly transferred.

When dumping booleans these need to be converted from the original DB representation
to the new db representation. In the case of most DBs this is simply to 0 or 1 but
for postgres these have to be false or true.

Now the below behaviours are allowed.
```Go
var id int64
var name string
has, err := engine.Table(&user).Cols("id", "name").Get(&id, &name)
// SELECT id, name FROM user LIMIT 1
```
```Go
rows, err := engine.Cols("name", "age").Rows(&User{Name:name})
// SELECT * FROM user
defer rows.Close()
for rows.Next() {
var name string
var age int
err = rows.Scan(&name, &age)
}
```

Now `Datetime` support `Datime(6)` to indicate the time scale. For different database , the max scale is not different.
`Datetime` means `Datetime(0)`.

There are two issues with #1872 which have become apparent
after testing on Gitea.
1. Ensure structs which are have before processors run correctly
2. Ensure structs extending other structs work
3. Ensure that numerical enums become numeric

When using dumptables to convert between dialects if a struct is provided we should use it to generate the SQL types rather than infer them by mapping from the sql types.

#1864 Export tag identifier so we can change that form `xorm` to others
This will be useful when in some migration scenarios such as migrate `sqlx` to `xorm`, the former uses `db` as the identifier and has a very simple rule which can be covered by xorm parser rules

Merge branch 'master' into logger-priority
put ContextLogger in higher priority
SetLogger use `Logger` when give a interface which implements both
ContextLogger and Logger. Because Go's type `switch` uses prior `case`.
