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).

There were no automated tests for this originally, so no test changes are here, but I've verified the correct behavior manually. Definitely need to add some automated tests before this gets flipped on by default again.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This patch was mostly generated with the following command:
find . -name "*.h" -o -name "*.cpp" | xargs sed -e '/WrapObject(JSContext/ {; N; s/\(WrapObject(JSContext *\* *a\{0,1\}[Cc]x\),\n\{0,1\} *JS::Handle<JSObject\*> a\{0,1\}[sS]cope/\1/ ; }' -i ""
and then reverting the changes that made to
dom/bindings/BindingUtils.h, since those WrapObject methods are not
the ones we're trying to change here, plus a bunch of manual fixups
for cases that this command did not catch (including all the callsites
of WrapObject()).
This patch was mostly generated with this command:

plus a few manual fixes to dom/bindings/Codegen.py, js/xpconnect/src/event_impl_gen.py, and a few C++ files that were not caught in the search-and-replace above.
