- provides expect,printerr_match for matching printerr output
- fails tests if printerr is called outside the printerr_match wrapper
- changes api of expect.error_match to mirror the new printerr_match api
This allows tests to test these functions without needing to include the test
wrapper directly (now ci/test.lua, formerly test/main.lua). Hopefully this
location is also more stable, similar to other libraries that are already tested.
