Show PID / TID / PTID in Thread status view

[bhufmann]

The Threads Status view, when using the Trace Compass server, doesn't show the PID, TID, PPID, etc. The Eclipse Trace Compass has columns in the tree left side of the view. This will help users to correlate data between views.

The data could be shown in the tree (see below) and/or in the tooltip. For that the Trace Compass server back-end needs to be updated to provide that info per row. The tree model already supports additional columns and only the data provide would need to be updated for that.
