Description

In order to make the grammar more consistent, to reflect the spec changes after CMIS 0.5 and to simplify processing the AST the following changes should be performed:

• Make nodes in grammar tree for AND, OR and NOT operators
• remove imaginary tokens BIN_OP and UN_OP as they do not provide value
• rename imaginary token BIN_OP_ANY to EQ_ANY (EQ is now the only allowed operator)
• use two different imaginary tokens SEL_LIST and IN_LIST for list of literals in SELECT and WHERE part (these are different things)
• Introduce new imaginary tokens IN_ANY, NOT_IN_ANY for <quantified comparison predicate> as this is a separate operator requiring its own processing
