<!-- Please describe your changes on the following line: --> Send all warnings and errors to the constellation. Warnings are bufferred up, and included in any subsequent error reports. Errors are reported in the same way as panics. Note that this can't merge yet, as it needs https://github.com/rust-lang-nursery/log/pull/86 to land. --- <!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: --> - [X] `./mach build -d` does not report any errors - [X] `./mach test-tidy` does not report any errors - [X] These changes fix #11776 (github issue number if applicable). - [X] These changes do not require tests because we don't test crash reporting. <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> Source-Repo: https://github.com/servo/servo Source-Revision: a5cd4b95183da4ae9b754d9d4824bd23f4ad7eb8
