Opening of LTTng trace fails when running theia-traceviewer and server on Windows

[bhufmann]

When opening a LTTng kernel trace (e.g. using Open With -> Trace Viewer) on Windows using the Trace Compass server in Windows fails with error: "Invalid trace(s): kernel"

To reproduce use Theia Blueprint for C https://download.eclipse.org/theia/c/1.17.2/windows/TheiaBlueprintForC.exe and Trace Compass server nightly build for windows: https://download.eclipse.org/tracecompass.incubator/trace-server/rcp/

Debugging in front-end shows that backend call tspClient.openTrace() returns error code 406 (NOT_ACCEPTABLE) with message "Illegal char <:> at index 2: /c:/Users/user/Desktop/ls-trace-20170217-141925/kernel"

This means that the trace server can't handle such path strings created by the front-end on Windows.

This issue is documented on the Theia IDE github: eclipse-theia/theia#8098.

Workaround for eclipse-theia/theia#8098 and additional required fixes are implemented in the trace server. See trace server Bug 577145 and Patch for that.

The trace compass server has been updated and a new server build is available: https://download.eclipse.org/tracecompass.incubator/trace-server/rcp/

I tested it with Theia Blueprint for C and it works now.

Opening it in Windows fails again. Changes in #554 make the Theia bug (eclipse-theia/theia#8098) visible again. It fails now during the execution of the theia-traceviewer code and the following error is shown:

A patch for a work around is available for review. Please see PR 674.
