When the notification server callback is executed by the Windows
notification system, it invokes Firefox with additional command line
parameters, most importantly the Windows-specific notification
"Windows tag".
If no appropriate Firefox is running, the command line will be
processed, the provided Windows tag will be inspected (and seen to not
be registered with this running Firefox instance) and a "launch URL"
stored as part of the Windows notification itself opened (if one is
provided).
If an appropriate Firefox is running, the remoting protocol will
forward this command line to the running instance. If the instance
recognizes the provided `--notification-windowsTag`, the command line
will be ignored. When the notification server exits, Windows will
fallback to the Windows 8.1 style notification callbacks registered
for this Windows tag and the existing (non notification server)
behaviour will occur.
In fact, the server therefore waits for a Windows tag-specific system
event to be signalled by the invoked Firefox (or a sibling process).
If we were to return `S_OK` from the notification server immediately,
and a running Firefox process would handle the notification via
Windows 8.1-style notification callbacks, then Windows would fall back
to those callbacks. The invoked callbacks unregister themselves upon
completion, often before the launched Firefox has an opportunity to
process the command line. By waiting for this system event, we allow
the invoked Firefox to process the command line while its own
notification callbacks are registered and therefore recognize that its
callbacks will handle the notification.

This was oversight. In background tasks, I took some care to provide
the snapshot of the default profile's targeting state to the Firefox
Messaging System, but it also needs to be provided to Nimbus to filter
experiments directly.
For expedience, I provide an extra targeting context object to
`ExperimentManager.onStartup`.
The targeting contexts for Nimbus proper and Firefox Messaging System
are somewhat independent; that's why the triggering context remains in
the invocation of `sendTriggerMessage`.

Nimbus features can now specify a list of applications they support (defaulting
to firefox-desktop). Enrollment for a given recipe will only occur if the
application supports all the features listed in the experiment. This allows
Firefox Desktop and the background task service to have different sets of
features, which prevents Firefox from enrolling in backgroundTaskMessage
experiments and the background task service from enrolling in experiments
intended for Firefox Desktop.

This patch moves EqualsIgnoreCase to ns[T]StringObsolete, and removes
the aCount argument, instead migrating callers to use `StringBeginsWith`
with a case-insensitive comparator.
In addition, nsTStringRepr::Compare was removed and replaced with either
calls to methods like `StringBeginsWith` or the global `Compare` method.
These changes required some modifications at call-sites but should make
the behaviour less surprising and more consistent.

This commit does several things:
1. It configures a new Nimbus feature and corresponding message group
`backgroundTaskMessage`.
2. It configures `Firefox Messaging Experiments` to use the new
Nimbus feature in background tasks. The existing Remote Settings
collection `nimbus-desktop-experiments` continues to be used.
These configurations are achieved by setting preferences in
`backgroundtasks_browser.js`, which is applied on top of
`firefox.js` prefs by the preference service. These preferences
apply to every background task.
3. It implements functions for enabling Nimbus and the Firefox
Messaging System (and Messaging Experiments) that can be used by
arbitrary background tasks.
It is assumed (but not enforced here) that such tasks will use
non-ephemeral (persistent) profiles, so that Remote Settings
incremental sync, Nimbus bucketing, and Messaging System message
limits, function as expected.
4. It adds a new `message` background task specifically for testing
background task messages. Invoke the testing task with command
lines like `firefox --backgroundtask message ...`.
To ease testing, the framework accepts `--url about:studies?...`
arguments from the Experimenter Web UI to explicitly opt-in to
specific experiment branches.
This task is complicated because it is intended both for QA to
manually invoke, but also to be used by automated tests.
Eventually the existing `backgroundupdate` task will use the new
functions, just as the testing `message` task does.

This is a little tricky since some behaviour must be in the profile
service while some is more naturally in the background tasks mechanism.
Essentially, some background tasks will have a consistent profile
location determined by their "profile prefix", which includes vendor,
installation hash, and background task name. Right now, those tasks are
determined by their task name, but in the future we could make this more
flexible.
A few technical notes:
1. I elected to not assume (or provide) a directory service provider
in the relevant helper, mostly to ease future commits that might
pull this functionality forward in the startup process.
2. These background task profiles are placed in "Background Tasks
Profiles" on relevant platforms (non-Unix and macOS), sibling to
"Profiles".
3. To avoid any possible vulnerability with predictable profile
directories, these non-ephemeral background task profiles are
salted. An entry is placed in the `BackgroundTasksProfiles` section
of `profiles.ini` mapping the profile prefix to the relative salted
path.

Temporary profiles mean different things in different contexts; for
example, the term is used in testing and the test harnesses.
I think ephemeral conveys what we're after well and will be easier to

The default browsing profile's targeting snapshot is read using the
standard `BackgroundTasksUtils.jsm` helpers, which allow setting the
profile location for testing.
The targeting snapshot is provided in the triggering context under
`defaultProfile`, allowing both the background task profile's
targeting (for things like current Firefox version and `currentDate`)
and the default browsing profile's targeting (for things like the
snapshot's `currentDate` and add-ons).

We take a simple approach:
1. We add a test to verify that all getters succeed in background
task mode (save for an exclusion list of getters that access
non-local hosts).
2. We make certain getters background task-aware: for example,
because they require the `AddonsManager` or legacy Telemetry.
This will allow background tasks to access their own targeting as well
as a snapshot of the default profile's targeting.

Several widget contracts use different implementations in the parent and
content processes. Since the static registration system builds its hashtable
at compile time rather than runtime, it doesn't support different contract IDs
per process. It could make the decision at lookup time, but given how rarely
it's needed, I don't think it would be worth the complexity.
This patch updates the widget components that need different implementations
in the parent and content process to register separate contracts for each
implementation, and a third stub contract which forwards to the appropriate
implementation depending on which process it's used in. The implementation
entries restrict their usage to the process they are meant to be used in.
