Could you add some comments about the added macros, e.g. what does V2VD1 in VA_TRACE_V2VD1 stand for ?

Could you add some comments about the added macros, e.g. what does V2VD1 in VA_TRACE_V2VD1 stand for ? update in comments/doc in each trace interface. please check again. the V is short for variable, data bitsize could be 8/16/32/64. the P is short for pointer, data bitsize could be 8/16/32/64. The A is short for array. all these marco interface is to have cleaner usage in va.c, each trace could contail diff number of data element, with diff data type like basic size and array.
