[PATCH 0/9] rteval: Fix measurement module hangs and improve test infrastructure

This series addresses critical bug fixes in measurement module error handling
and significantly improves rteval's test infrastructure.

Patches 1-2: Critical bug fixes for measurement modules
  Fix hangs in timerlat and cyclictest when measurement tools crash or produce
  malformed output. Both modules now properly handle partial output, limit
  SIGINT retries, and ensure cleanup always completes.

Patches 3-5: Testing and configuration improvements
  Add comprehensive regression tests to verify error handling fixes, update
  config files for clarity, and fix e2e test patterns to match current output.

Patches 6-9: Test infrastructure organization
  Refactor and consolidate all tests under tests/ directory with consistent
  naming (unit-tests, e2e-tests, regression-tests, cpuset-tests). Move cpuset
  tests from local/ to tests/cpusets/ with comprehensive documentation.

Key improvements:
- Prevents rteval hangs when measurement tools crash (RHEL-140898, RHEL-172903)
- Adds regression tests with mocked failure scenarios
- Consolidates test infrastructure under tests/ directory
- Provides consistent Makefile targets for all test types
- Includes comprehensive test documentation
