`insertSelectPlaceholder` is an unexported const set at true. No code changes this nor can any build environment change it.
Therefore we should remove it and the associated dead code.

The current mechanism for adding information about indices cannot express the ordering
of the columns in the index or add sorting information.
Here we add a new interface TableIndices which a struct would implement to provide
a slice of *schema.Index to provide additional indices to that gleaned from the tags.

MySQL/MariaDB: return max length for text columns using `CHARACTER_MAXIMUM_LENGTH`.
Tests:
* add an integration test: `TestGetColumnsLength`
* update `TestSyncTable3` since `TableInfo` isn't able to provide the column size

The [oldest unsupported version documentation](https://www.postgresql.org/docs/7.1/sql-comment.html) states that comment on a column is supported.
Update `TestGetColumnsComment` in order to check both MySQL/MariaDB and PostgreSQL.

ref pr https://gitea.com/xorm/xorm/pulls/2053
i think the previous fix has some issue
for example, i'm using session like this:
```go
// logSessionID == false
engine := NewEngine()
// use ctx.SessionId to distinguish uniq request id
cxt := context.WithValue(parent, log.SessionIDKey, "some unique request id")
session := engine.NewSession().Context(ctx)
```
however, with pr 2053, `session.Context` can't get SessionId from ctx.
this pr fix abrove issue, overwrite `session.Context()` only when `engine.logSessionID == true`
please check it out,thanks!

when using distinct cols with FindAndCount, reset statement.ColumnMap will make the counting sql an syntax error, this pr try fix this.
is this pr ok for merge?
error sql logging:
```sql
[SQL] SELECT DISTINCT `Fid` FROM `table_demo` WHERE Fkey = ? [val]
[SQL] SELECT count(DISTINCT ) FROM `table_demo` WHERE Fkey = ? [val]
```
after fix:
```sql
[SQL] SELECT DISTINCT `Fid` FROM `table_demo` WHERE Fkey = ? [val]
[SQL] SELECT count(DISTINCT `Fid`) FROM `table_demo` WHERE Fkey = ? [val]
```

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.

The behavior of multi insertion of null differs from that of single insertion.
On the other hand, behavior between single and bulk insertion of null using pointer of struct field is identical.
Please see the example below.
```go
s := engineGroup.NewSession()
type User struct {
ID int `xorm:"not null pk autoincr INT(10)"`
Name string `xorm:"not null VARCHAR(191)"`
Age int64 `xorm:"null BIGINT(20)"`
}
list := []*User{
{
Name: "John",
},
{
Name: "Wick",
},
}
s.Nullable("age")
// Single insertion works
_, err := s.Insert(list[0]) // [table] `user` INSERT INTO `user` (`name`,`age`) VALUES (?, ?) [John <nil>]
s.Nullable("age")
// Bulk insertion does not work
_, err := s.Insert(list) // [table] `user` INSERT INTO `user` (`name,`age`) VALUES (?, ?),(?, ?) [John, 0, Wick, 0]
//---------------------------------
//Using pointer, which is nullable, the generated sql has no difference.
//---------------------------------
type User struct {
ID int `xorm:"not null pk autoincr INT(10)"`
Name string `xorm:"not null VARCHAR(191)"`
Age *int64 `xorm:"null BIGINT(20)"`
}
list := []*User{
{
Name: "John",
},
{
Name: "Wick",
},
}
s.Nullable("age")
// Single insertion works
_, err := s.Insert(list[0]) // [table] `user` INSERT INTO `user` (`name`,`age`) VALUES (?, ?) [John <nil>]
s.Nullable("age")
// Bulk insertion does not work
_, err := s.Insert(list) // [table] `user` INSERT INTO `user` (`name,`age`) VALUES (?, ?),(?, ?) [John, <nil>, Wick, <nil>]

# Issue
Such a following query is executed in master DB node with EngineGroup.
```go
s := engineGroup.NewSession(); // create session from EngineGroup.
sql := `
SELECT * FROM USER;
`;
type User struct { ... };
var users []User;
err := s.Sql(sql).Find(&users); // executed to master DB node.

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)
}
