Assorted Fixes #5

[manticore-projects]

0. SQL:2016 Standard compliant Unicode characters based on https://www.unicode.org/Public/UNIDATA/UnicodeData.txt and its Categories

1. Merge REPLACE into UPSERT

   • Support SQLite REPLACE OR INSERT ...
   • Fixes Unable parse OR #1706

2. DROP TEMPORARY TABLE ...

   • Fixes Encountered unexpected token: "temporary" "TEMPORARY" #1712

3. feat: Configurable backslash \ escaping

   • Enables \ as escape character in String Literals (beside SQL:2016 compliant ')

     select 
         case 
         when id_portfolio like '%\_1' escape '\' 
         then '1'
         end

     (which even the GitHub Syntax Highlighter fucks up 👍 )

   • Default is OFF (since its not SQL:2016 compliant)

   • Activate per Parser Feature

     String sqlStr = "select case \n"
                    + "    when id_portfolio like '%\\_1' escape '\\' then '1'\n"
                    + "    end";
     TestUtils.assertSqlCanBeParsedAndDeparsed(
            sqlStr
            , true
            , parser -> parser.withBackslashEscapeCharacter(false)
     );
     
     Assertions.assertThrows(JSQLParserException.class, new Executable() {
        @Override
        public void execute() throws Throwable {
            CCJSqlParserUtil.parse(
                    sqlStr
                    , parser -> parser.withBackslashEscapeCharacter(true)
            );
        }
     });
