sql_mode=MSSQL: Bracket identifiers

SQL Server understands bracket identifiers (in addition to the SQL Standard double-quoted identifiers), so these scripts are equivalent:

SELECT

  [column]

FROM

  [my table]

WHERE

  [order] = 10;

SELECT

  "column"

FROM

  "my table"

WHERE

  "order" = 10;

We'll extend the parser to understand bracket identifiers when sql_mode has the MSSQL flag.

Bracket identifiers will be accepted in all contexts where double-quoted identifiers are possible, including but not limited to:

• Direct SQL
• Dynamic SQL (PREPARE/EXECUTE/EXECUTE IMMEDIATE)
• Stored procedures

This will help SQL Server users to migrate to MariaDB easier.
