Add unit_tests_run that (mostly) works for all of linux, OSX and Windows.

Revert r134607 "Revert r134508 "Revert 134507, broke the main builders:""

Overall, this reapplies r134507.

The dependencies were retrieved with trace_inputs.py and merged with merge_isolate.py.

Manual edits:
- Added <(EXECUTABLE_SUFFIX) to two executables: unit_tests and xdisplaycheck.
- Removed testserver.log and unit_tests.log.
- Added copyright.
- Removed *.db-journal files.
