cpukit/capture: Update the capture engine.

Browse Source 
The capture did not work due to changes in the workspace allocator.
The engine now scans all existing tasks when enabled and does any
allocations then.

Fixed a bug in the ctset commandi in the CLI.

Updated the capture engine to use 64bit nanosec timestamps.

Fixed the CLI showing the stack usage.
