servo: Merge #20391 - Measure cache memory usage (from modal17:iss19251); r=jdm <!-- Please describe your changes on the following line: --> - [X] make the memory cache data structure derive MallocSizeOf - [X] add a new IpcReceiver argument to ResourceChannelManager::start that is used for listening to messages from the memory profiler (it must correspond with this sender) - [X] use run_with_memory_reporting in the network code to register a memory reporter for that thread - [X] when a message from the memory profiler arrives, create a report that includes that size of the public and private http caches --- <!-- 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 #19251 (github issue number if applicable). <!-- Either: --> - [ ] There are tests for these changes OR - [ ] These changes do not require tests because _____ <!-- Also, please make sure that "Allow edits from maintainers" checkbox is checked, so that we can help you if you get stuck somewhere along the way.--> <!-- 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: 8f226f841bd5e1ab412ff2cd8417919b222f7555
