Remove some unsound JSVal handling in JsTimerTask::invoke.
We were using Handles to *copies* of the traced values, rather than the
originals.

An in-memory RNG that shares its file descriptor.
<!-- Please describe your changes on the following line: -->
This PR implements an in-memory random number generator that only uses an OS RNG for (re)seeding. The OS RNG is shared, so there's only one file descriptor for `/dev/urandom` being used.
The PR also implements a tidy check that we don't accidentally introduce an RNG. Rather annoyingly, there are a lot of transitive dependencies on `rand`, notably hash maps in `std`.
This PR makes it possible to use uuids for identifiers such as pipeline and frame ids.

webgl: implement bufferData
<!-- Please describe your changes on the following line: -->
Adds support for the other overload of bufferData, fixing many conformance tests. In the process I had to fix the webidl codegen in the overload-distinguished-by-an-object case. Also includes a little fix for glEnable() validation.

I was writing this to fix the error in gl-enum-tests.html test (it now
gets farther along before it fails due to us missing
getTexParameter()), but it turned out that a lot of the conformance
tests were failing due to it.
Implement discarding Document objects to reclaim space.
<!-- Please describe your changes on the following line: -->
This PR implements document discarding. Active documents are kept alive strongly, but inactive documents are only kept alive weakly. When a document is GCd, it is marked as discarded, and if it is every reactivated, a reload of the URL is triggered.
Note that this PR is pretty aggressive about discarding, and can any inactive document (other than those being kept alive by other same-origin pipelines). We might want to damp it down a bit.
Also note that this interacts with browser.html in that the reloading triggered by reactivating a document triggers mozbrowser events.
To test this, I added a `-Zdiscard-inactive-documents` debug flag, which discards all inactive documents, even ones which are reachable through other same-origin pipelines.

Properly dispatch keypress event
<!-- Please describe your changes on the following line: -->
This was an attempt to fix#14659. It turned out that the problem wasn't what I thought it was. So, I didn't fix that. On the brighter side, this fixes two related issues.
- Previously, we were unable to launch `keypress` events from `input` and `textarea` elements, because [we'd been cancelling](1327ebd52f/components/script/dom/htmlinputelement.rs (L1120-L1124)) the key events, so that they don't trigger window navigation - #8400). I've introduced an enum to represent an additional state to an event's cancellation.
- [According to the spec](https://w3c.github.io/uievents/#keypress-event-order), `keypress` (if available) should be dispatched immediately after `keydown`, and it should be followed by `input`. Canceling `keypress` should also cancel `input`. But, we'd been dispatching `input` before `keypress`. We now dispatch `input` once the `keypress` event is on the respective elements.

Fix inline layout of table cells impacted by rowspan
This is part of the fix for #11297. This PR fixes the inline layout of table cells impacted by row-spanning cells from previous rows. A separate PR to follow will fix the table block size calculations to account for rowspan.
This PR doesn't yet include any test changes. If it doesn't cause any existing tests to pass, I will add a new test to it.
