@jdm - this is the new profiler : "Blocked at IPC Receive"
Should I dig through all the calls to `ipc::channel` and replace them with this profiled `IpcReceiver`?

I wonder if I should also refactor the
`pub fn profile<T, F>(category: ProfilerCategory, meta: Option<TimerMetadata>, profiler_chan: ProfilerChan, callback: F) -> T where F: FnOnce() -> T method ` , but I don't feel confident enough to make the call, since I don't really understand what it would imply.

This PR implements the current draft Houdini Worklets specification (https://drafts.css-houdini.org/worklets/).
The implementation is intended to provide a responsive environment for worklet execution, and in particular to ensure that the primary worklet executor does not garbage collect, and does not block loading module code. The implementation does this by providing a thread pool, and performing GC and module loading in a backup thread, not in the primary thread.

With this change, if you supply the `-Z signpost` flag, Instruments.app
can display Servo events overlaid with callstack data. Even better, you
can get call stack profiling for individual Servo events (one layout,
one network request, one style recalculation, etc.)
This adds a dependency on the `signpost` crate. On unsupported OS's,
this crate is an no-op.

This happens asynchronously, just as it does in non-WebRender mode.
This functionality is a prerequisite for doing proper display-list-based
hit testing in WebRender, since it moves the scroll offsets into Servo
(and, specifically, into the script thread, enabling iframe event
forwarding) instead of keeping them private to WebRender.
Requires servo/webrender_traits#55 and servo/webrender#277.
Partially addresses #11108.

This PR fixes#10886. The -p option can be followed by either an interval number or a CSV filename.
* In the interval profiling, the profiler output would be spitted out to the terminal periodically.
Example usage: **./mach run -p 1 http://www.google.com** will print the time-profiling output to the terminal every second.
* In the CSV file profiling, a CSV file will be generate upon termination of servo.
Example usage: **./mach run -x -o out.png -p out.csv http://www.google.com** will generate out.csv upon termination of Servo.

This commit adds the `--profiler-trace-path` flag. When combined with `-p` to
enable profiling, it dumps a profile as a self-contained HTML file to the given
path. The profile visualizes the traced operations as a Gantt-chart style
timeline.
Example output HTML file: http://media.fitzgeraldnick.com/dumping-grounds/trace-reddit.html
Mostly I made this because I wanted to see what kind of data the profiler has, and thought that this might be useful for others as well. I'm happy to add tests if we can figure out how to integrate them into CI, but I'm not sure how that would work.
Thoughts?

The old code tried to do the speculation as a single bottom-up pass
after intrinsic inline-size calculation, which was unable to handle
cases like this:
<div>
<div style="float: left">Foo</div>
</div>
<div>
<div style="overflow: hidden">Bar</div>
</div>
No single bottom-up pass could possibly handle this case, because the
inline-size of the float flowing out of the "Foo" block could never make
it down to the "Bar" block, where it is needed for speculation.
On the pages I tried, this regresses layout performance by 1%-2%.
I first noticed this breaking some pages, like the Google SERPs, several
months ago.

Right now, the only reason that overflow calculation works is that we
rely on script inducing extra reflows that are sent for display. This
was preventing #10021 from landing.
This change regresses layout performance by about 1% in my tests.
Fixes#7797 properly.

Instead of producing a tree of stacking contexts, display list
generation now produces a flat list of display items and a tree of
stacking contexts. This will eventually allow display list construction
to produce and modify WebRender vertex buffers directly, removing the
overhead of display list conversion. This change also moves
layerization of the display list to the paint thread, since it isn't
currently useful for WebRender.
To accomplish this, display list generation now takes three passes of
the flow tree:
1. Calculation of absolute positions.
2. Collection of a tree of stacking contexts.
3. Creation of a list of display items.
After collection of display items, they are sorted based upon the index
of their parent stacking contexts and their position in CSS 2.1
Appendeix E stacking order.
This is a big change, but it actually simplifies display list generation.

This is a fix for #8468.
Currently XHR timeouts schedule themselves for execution via `CommonScriptMsg::RunnableMsg`s. This was necessary when these timeouts used a separate thread to schedule themselves. Now it's a potential race that should have been eliminated as part of #8168.

Source-Revision: 49d48a8680003267f29ebf8cd47c244b07f4c4d2
This is an rough solution to the issue described in #3396. XHRs still do their own thing and an overall clean up is in order. Before I do that, though, I'd really like someone to sign off on the overall idea.
There's one major difference to what jdm layed out #3396: The timers remain with the window/worker and only the earliest expiring one is coordinated with the dedicated timer thread.
That means both the timer thread and the window/worker have to keep track of which timer expires next, which feels a bit wonky. However, the upshot is that there's no need for communication with the timer thread when a pipeline is frozen, thawed or dropped.
Most relvant parts are
- the [`TimerScheduler`](6f5f661958 (diff-74137a6f50ab38e7a1e4d16920a66ce7R73)), which is the new per-constellation timer task and
- the [`ActiveTimers`](6f5f661958 (diff-86707d952414a2860b78bcf6c1db8e2eR34)) which is what's left on the window/worker side.

Add the energy-profiling feature. Users can compile the proper (or their own) version of energymon libraries to capture power/energy data at runtime. The results are accessed through heartbeats.

This PR adds Heartbeats capability to servo. Heartbeats are used for detailed performance and power/energy profiling. We will add the power/energy readings in the future.
New dependencies are introduced which need in-depth reviews. I'm the only one who has had eyes on any of this, and I have limited resources for testing cross-platform compatibility.
* https://github.com/libheartbeats/heartbeats-simple - provides native C libraries from a shared code base:
* hbs[-static] - performance monitoring
* hbs-acc[-static] - performance with accuracy monitoring
* hbs-pow[-static] - performance with power/energy monitoring (the one we're using)
* hbs-acc-pow[-static] - performance with accuracy and power/energy monitoring
* https://github.com/connorimes/heartbeats-simple-sys provides rust wrappers for the native C libraries above - one crate for each + a common crate. These link with the *-static versions of the heartbeats libraries.
* https://github.com/connorimes/heartbeats-simple-rust provides rust abstractions over the -sys crates above - one crate for each.
The new `heartbeats` module in the `profile` crate looks for environment variables telling it to use heartbeats for each ProfilerCategory and where to put log files. (Of course, if somebody knows how to iterate over the enum instead of hardcoding each one, that would be fantastic.) If the environment variables aren't set for particular categories, heartbeats aren't created or used.
An interface change is made in the `profile_traits` crate to pass both the start and end time in a `ProfilerMsg` instead of just the elapsed time. Later we will add energy readings as well.

A rebuild after touching components/profile/mem.rs now takes 48 seconds (and
only rebuilds `profile` and `servo`) which is much lower than it used to be.
In comparison, a rebuild after touching components/profile_traits/mem.rs takes

This change also removes some unnecessary crate dependencies in `net` and
