Bug 1322611 - After a crash compute the SHA256 hash of a minidump and attach it to the crash ping; r=Ted, nchen
This patch changes the crashreporter client code as well as the crash service code to compute a SHA256 hash of a crash' minidump file and add it to the crash ping. The crash service code computes the hash on the fly before handing over the crash to the crash manager; the crash manager will then add it to the crash ping. The crashreporter client on the other hand sends the hash via the ping it generates but it also adds it to the event file so that the crash manager can pick it up and send it along with its own crash ping. On Fennec the crashreporter activity takes care of computing the hash. SHA256 hash computation uses nsICryptoHash in the crash service, the java.security.MessageDigest class in Fennec, the bundled NSS library in the crashreporter when running on Windows and Mac and the system-provided NSS library under Linux. The latter is required because the crashreporter client uses the system curl library which is linked to NSS and which would thus clash with the bundled one if used together. This patch introduces two new methods for the nsICrashService interface: |getMinidumpForID()| and |getExtraFileForID()|, these reliably retrieve the .dmp and .extra files associated with a crash and ensure the files exist before returning. These new methods are used in the CrashService for processing and will become the only way to reliably retrieve those files from a crash ID.
