REVISION SUMMARY
  This is a bunch of small changes that together enable running tests from
  CMake with support for QtTest and viewing results in the tool view.
  The changes include:
  
  1. Enable listing test cases from tests defined with CMake and QtTest
    - Extract sources for each target from cmake server
    - Use target sources to look for QtTest declarations in them
    - Fix the search for QtTest declarations, so that it works without access to the main() function body
  
  2. When running tests, parse the output and report results
    - Exctract output directly from the OutputModel, which is long-lived, and not from the shorter-lived OutputJob. The previous method would lose some lines of output.
    - Wait for asynchronous output signals from OutputModel, which again prevents losing some lines of test program output.
