This patch changes Firefox Health Report to pull crash counts from the
newly-implemented crash manager. The crash manager is now the canonical
source of crash data, so all the code for reading crash dump files from
disk has been removed.
This regresses the collection capability of Firefox Health Report by
removing plugin crashes and hangs from the reported values. This
regression is intended to be temporary and a follow-up bug will be
created to add plugin process event recording to the crash events
system.
This regression has been justified because the old crash reporting
mechanism was severely flawed and wasn't sending accurate data (not all
crashes were being saved to dumps and some dumps would be deleted).

This patch institutes limits for how much crash data can be stored in
terms of maximum number of crash events per day. If more events than the
limit are encountered, we record that a high water mark has been
encountered and we silently discard the payload of future events.
We chose to not increment the version of the store payload because no
clients are actively saving this data yet, so it doesn't make sense to
incur a version bump.

The initial implementation of this feature will write 3 distinct event
types and will only count occurrences of each. Future iterations of the
feature will capture more metadata, such as submission state and extra
crash annotations. These will not be included in this patch set.

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.
