Sphinx has been complaining about a number of reStructuredText warnings
for a while. Fix all the ones in .rst files.
Not asking for review because this is docs only and changing .rst files
can't break anything important.

There was a hard-coded date in test_crash_manager.js of around August 3,
2013. This meant that about a year later we would start to run into
boundary issues since we weren't wrapping Date.now() inside
CrashManager.jsm.
It turns out the actual value of DUMMY_DATE doesn't really matter. So,
the test has been changed to produce a value that is reasonably modern.
While I was debugging this, I noticed we're not getting logging in the
tests. So I added that.

This introduces a new crash event type for submissions and handles
them in the Crash Manager. These crash submissions will also be counted
in FHR.

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).

If an xpcshell test called run_next_test() from inside an add_task(),
bad things would happen. This patch detects that behavior and aborts the
test immediately with an actionable error message.

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.

Support for main process crashes, plugin crashes, and plugin hangs is
added to the crash manager. This includes a JS API for reporting them as
well as support for reading the event files.
There is still an issue of unbound growth on the store. This will be
addressed in a subsequent patch.

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.

The tree doesn't have a robust and reusable API for interfacing with
crash data. This patch is the start of a new API.
In this patch, the CrashManager type is introduced. It has APIs for
retrieving the lists of files related to crash dumps. In subsequent
patches, I will convert existing code in the tree that does similar
things to the new API. I will also build the events/timeline API onto
this type.
I made CrashManager generic because I hate, hate, hate singletons and
global variables. Allowing it to be instantiated multiple times with
different options (instead of say binding a global instance to ProfD)
makes the testing story much, much nicer. That is reason enough, IMO. In
a subsequent patch, I'll add an XPCOM service that instantiates the
"global" instance of CrashManager with the appropriate options.
It was tempting to add this code into the existing CrashReports.jsm.
However, this file does not import cleanly in xpcshell tests and I
didn't want to bloat scope to include fixing that file... yet.
CrashReports.jsm is using synchronous I/O. So, depending on how
adventerous I feel, I may replace consumers of CrashReports.jsm with the
new CrashManager.jsm, remove CrashReports.jsm, and eliminate another
source of synchronous I/O in the tree.
