This introduces the machinery needed to generate crash annotations from a YAML
file. The relevant C++ functions are updated to take a typed enum. JavaScript
calls are unaffected but they will throw if the string argument does not
correspond to one of the known entries in the C++ enum. The existing whitelists
and blacklists of annotations are also generated from the YAML file and all
duplicate code related to them has been consolidated. Once written out to the
.extra file the annotations are converted in string form and are no different
than the existing ones.
All existing annotations have been included in the list (and some obsolete ones
have been removed) and all call sites have been updated including tests where
appropriate.

Much like the component manager, many of the strings that we use for category
manager entries are statically allocated. There's no need to duplicate these
strings.
This patch changes the category manager APIs to take nsACStrings rather than
raw pointers, and to pass literal nsCStrings when we know we have a literal
string to begin with. When adding the category entry, it then skips making
copies of any strings with the LITERAL flag.

Aside from making things easier for JS callers, this also makes it harder to
accidentally trigger an early load of the service, which can be expensive
during startup.
This also makes a slight change to nsPluginHost to initially preserve the
previous blocklist state when a plugin is updated, to avoid the risk of the
possible additioanl asynchrony unblocking a plugin that should stay blocked.

This changes the pluginreg.dat format to include the blocklist state.
There is now only the saved blocklist state in a plugin tag instance, rather than
looking it up from in there using the blocklist service, so it was renamed from
mCachedBlocklistState to mBlocklistState. We pass the 'right' state to the plugin
instance when the plugintag is constructed. If we don't have state, we mark it as
unblocked.
mCachedBlocklistStateChanged was never read so it's being removed.
Bug 1439519 adds a 'blocklist-loaded' notification that is fired once the blocklist is loaded.
The plugin host implementation will listen to this in the parent process and update the
blocklist state of all the plugins, and broadcast changes to the child process, just like when
we update the blocklist from the server. We now also avoid re-sending plugin content to the
content processes if the plugin state hasn't changed as a result of the blocklist having been
loaded.
Finally, because new plugins should still get an up-to-date blocklist state, and
telemetry should get up-to-date data about which plugins are and aren't enabled
once we have that data, we ensure that once we've loaded the blocklist async,
we schedule an idle task to parse it and consider it loaded.
All this means that plugin blocklist information could be mistaken between the points where
a new plugin is installed and we first run Firefox with the new plugin, and the point where
we load the blocklist. Given the trade-offs, that size of window (tiny) seems OK, also given
that there's already a much larger window in blocklist updates (which only happen once every 24h).

This is a follow-up to bug 1409249. There are a lot of places where our
factory singleton constructors either don't correctly handle their returned
references being released by the component manager, or do handle it, but in
ways that are not obvious.
This patch handles a few places where we can sometimes wind up with dangling
singleton pointers, adds some explanatory comments and sanity check
assertions, and replaces some uses of manual refcounting with StaticRefPtr and
ClearOnShutdown.
There are still some places where we may wind up with odd behavior if the
first QI for a getService call fails. In those cases, we wind up destroying
the first instance of a service that we create, and re-creating a new one
later.

Instead of synchronously checking the blocklist, package each plugin's
blocklist state with it when sending the information to the content
process. Whenever the blocklist is changed, just resend the whole
plugin list.

It's silly to use prmem.h within Firefox code given that in our configuration
its functions are just wrappers for malloc() et al. (Indeed, in some places we
mix PR_Malloc() with free(), or malloc() with PR_Free().)
This patch removes all uses, except for the places where we need to use
PR_Free() to free something allocated by another NSPR function; in those cases
I've added a comment explaining which function did the allocation.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those
required by the changes described above).
- Fixes a bunch of labels that had gotten out of sync with the name of the
class and/or function that encloses them.
- Removes a useless PROFILER_LABEL use within a trivial scope in
EventStateManager::DispatchMouseOrPointerEvent(). It clearly wasn't serving
any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.
- Tweaks DecodePool::SyncRunIf{Preferred,Possible} so that the labelling is
done within them, instead of at their callsites, because that's a more
standard way of doing things.

If we don't increment the plugin epoch in the parent process before
the first call to LoadPlugins, and all plugin info is already cached,
the epochs will match and we'll never get a complete plugin list in
the child. This patch makes sure our first parent/child epoch check
never matches, so we always update correctly.
