Servo currently uses `heapsize`, but Stylo/Gecko use `malloc_size_of`.
`malloc_size_of` is better -- it handles various cases that `heapsize` does not
-- so this patch changes Servo to use `malloc_size_of`.
This patch makes the following changes to the `malloc_size_of` crate.
- Adds `MallocSizeOf` trait implementations for numerous types, some built-in
(e.g. `VecDeque`), some external and Servo-only (e.g. `string_cache`).
- Makes `enclosing_size_of_op` optional, because vanilla jemalloc doesn't
support that operation.
- For `HashSet`/`HashMap`, falls back to a computed estimate when
`enclosing_size_of_op` isn't available.
- Adds an extern "C" `malloc_size_of` function that does the actual heap
measurement; this is based on the same functions from the `heapsize` crate.
This patch makes the following changes elsewhere.
- Converts all the uses of `heapsize` to instead use `malloc_size_of`.
- Disables the "heapsize"/"heap_size" feature for the external crates that
provide it.
- Removes the `HeapSizeOf` implementation from `hashglobe`.
- Adds `ignore` annotations to a few `Rc`/`Arc`, because `malloc_size_of`
doesn't derive those types, unlike `heapsize`.

Webdriver browsing contexts not pipelines
<!-- Please describe your changes on the following line: -->
At the moment, a webdriver session stores a `pipeline_id`s, which causes a mismatch with the spec, which asks a session to store a browsing context and a top-level browsing context. This PR fixes this mismatch.

Don't update iframe pipeline until load completes
To preserve the previous functionality of delaying load events when a
new navigation is triggered, pending pipeline id represents the
current pending load. The load event is only fired if the load message's
pipeline id matches the pending pipeline id.
Track frame size on Frame instead of Pipeline
Disabled matchMedia test
Track creator pipeline id
Sometimes clippy gets outdated by months, and its current support setup
means that each Servo component need to opt into it by depending on
the plugins crate manually, and not all components do that.
Allow script timeouts to be optional and associate timeouts with session state
These changes let WebDriver script timeouts be optional and associated all timeout state with the session. Because the durations are currently associated with the handler which is never reset, they bleed across to any subsequent WebDriver sessions.
See each individual commit for more information.

The script timeout duration may be set to null, indicating that an
injected script should run indefinitely without getting interrupted.
This change fixes the internal data structure, but does not address the
parsing of the input arguments to handle_set_timeouts.
The WebDriver timeout configuration durations should be associated with
the session so that they do not bleed across sessions. Since they are
currently stored on the WebDriverHandler, a call to the SetTimeouts
command will cause them to affect the subsequent session.
The WebDriver standard never defined acceptSslCerts, but it was used
by legacy Selenium implementations. The standard does however define a
slightly more negative-sounding capability called acceptInsecureCerts,
which to greater extent warns users about what its consequences are.
The WebDriver standard no longer specifies that the takeScreenshot and
takeElementScreenshot capabilities since it is assumed that all driver
implementations must support these features.
