rfe: Allow lenient input for NumberFormat.parse.

Name: bb33257 Date: 02/20/98


NumberFormat.parse method should allow lenient input. For example,
parsing "12\u0663\u0664.\u06667" should return "1234.67" if the
formatting object uses English decimal format symbols and return
"\u0661\u0662\u0663\u0664.\u0666\u0667" if the formatting object
uses Arabic decimal format symbols.
