/*
* Trace item
* ==========
*
* A trace item contains a trace header, a timestamp, a UID and a
* data header all of which are 32-bit and mandatory. If there
* is no data then the data header size is set to 0.
*
* Trace header
* ------------
* 31 27 23 19 15 11 7 3
* GGGG GGGG CCCC CCCC TTTT TTTT TTTT TTTT
*
* G = group
* Note:
* Group 0xff means the message is padding
*
* C = class
* T = Token
*
* Data header
*-----------
* 31 27 23 19 15 11 7 3
* SSSS SSSS SSSS SSSS TTTT CCCC CCCC CCCC
*
* S = data packet size
* T = Type
* 0000 - 8 bit
* 0001 - 16 bit
* 0010 - 32 bit
* 0011 - 64 bit
*
* C = data item count
*
* Note: It might look strange having both the packet
* size and the data item count, but the idea
* is the you might have a "special" data type
* who's size might not be known by the post
* processing program and rather then fail
* processing the buffer after that point if we
* know the size we can just skip it and move to
* the next item.
