* ensure capitalize doesn't take an inferred sink parameter
* sink parameter inference: first version, for now disabled. Changed that sink parameters can be consumed multiple times in order to adhere to our spec.
* sink inference can now be disabled with .nosinks; sometimes for proc type interop this is required
* fixes yet another critical DFA bug
* better implementation that also understands if expressions etc
* document sink parameter inference and allow for global disabling
* assertions: properly fix#11545
* tests/assert: enable excessiveStackTrace
* tests/assert: add test case for #11545
* tfailedassert_stacktrace: disable excessiveStackTrace
* assertions: weird workaround for failing tests
This fixes megatest on *nix, but have no idea why
