This patch introduces the concepts of the "crash data store" and "crash event files." The "crash data store" is a data store containing information about crashes. Data is added to this store directly through a JavaScript API or by the presence of "crash event files." A "crash event file" is simply an individual file containing information about a crash event. These files are periodically scanned and their contents are merged into the store. Currently, no specific event files types are defined. This patch merely begins to implement the infrastructure for dealing with them. Support for specific crash events will be added in subsequent patches. --HG-- extra : rebase_source : c58017b514f31c2823bc8ef4158a42bba758a9ab
