This patch removes the C++ code used to run the minidump analyzer when a content process crashes, and replaces it with JS code within the CrashService object. This removes the need for a separate shutdown blocker in C++ code and allows end-to-end testing of the crash service functionality. Additionally the exception handler code can be simplified since it's now only used to run the crash reporter client. The test added to test_crash_service.js covers computing the minidump SHA256 hash (bug 1322611) and of the minidump analyzer itself (bug 1280477). MozReview-Commit-ID: LO5w839NHev
