Chrome sets both KeyboardEvent.keyCode and KeyboardEvent.charCode of "keypress"
event to same value. On the other hand, our traditional behavior is, sets
one of them to 0.
Therefore, we need to set keyCode value to charCode value if the keypress
event is caused by a non-function key, i.e., it may be a printable key with
specific modifier state and/or different keyboard layout for compatibility
with Chrome. Similarly, we need to set charCode value to keyCode value if
the keypress event is caused by a function key which is not mapped to producing
a character.
Note that this hack is for compatibility with Chrome. So, for now, it's enough
to change the behavior only for "keypress" event handlers in web content. If
we completely change the behavior, we need to fix a lot of default handlers
and mochitests too. However, it's really difficult because default handlers
check whether keypress events are printable or not with following code:
> if (event.charCode &&
> !event.altKey && !event.ctrlKey && !event.metaKey) {
or
> if (!event.keyCode &&
> !event.altKey && !event.ctrlKey && !event.metaKey) {
So, until we stop dispatching "keypress" events for non-printable keys,
we need complicated check in each of them.
And also note that this patch changes the behavior of KeyboardEvent::KeyCode()
when spoofing is enabled and the instance is initialized by initKeyEvent() or
initKeyboardEvent(). That was changed by bug 1222285 unexpectedly and keeping
the behavior makes patched code really ugly. Therefore, this takes back the
old behavior even if spoofing is enabled.

Add the first version of the IPDL-JS API, which allow chrome JS to load IPDL files and use them to communicate accross Content processes.

After these patches, these objects will no longer be globals, which would make
their current names misleading. Parts 1a-1c give more appropriate names to the
bindings which will cease to be globals.

This is the first basic implementation of a shared-memory key-value store for
JS message managers. It has one read-write endpoint in the parent process, and
separate read-only endpoints for each child-process message manager.
Changes to the parent endpoint are broadcast to the children as snapshots.
Each snapshot triggers a "change" event with a list of changed keys.
It currently has the following limitations:
- It only supports basic structured clone data. There's no support for blobs,
input streams, message ports... Blob support will be added in a follow-up
patch.
- Changes are currently only broadcast to child endpoints when flush() is
explicitly called in the parent, or when new child processes are launched.
In a follow-up, this will be changed to automatically flush after changes
when the event loop is idle.
- All set operations clone their inputs synchronously, which means that
there's no trivial way for callers to batch multiple changes to a single key
without some additional effort. It might be useful to add a
delayed-serialization option to the .set() call in a follow-up, for callers
who are sure they know what they're doing.

Some notes: this does not fully bring us to compliance to the current spec.
Instead, these are the fixes that I needed to make in order to make
css/geometry/interfaces.html pass with the DOMPoint changes in the previous
patches. I don't fully understand why that patch caused the test to fail the
way it did, but it ended up being easier to fix our code than understand why
the harness was falling over.
The DOMQuad::QuadBounds class was the source of some confusion for me. Now
that DOMRectReadOnly is a concrete class with members, I wanted to avoid
wasting them. However, the spec is unclear as to whether a DOMQuad's bound's
should be live -- that is because DOMQuad exposes DOMPoint, we can set its
points after retrieving a QuadBounds object. Our current code is live, setting
the points changes the QuadBounds. Chromium's current behavior is to never
update the QuadBounds object. I've left our behavior untouched in this patch
(and waste 4 doubles per QuadBounds object), but I am intending to file a bug
to understand what the intent of the spec is. I wonder if the author intended
the points to be DOMPointReadOnly instead. If so, we could simplify the
DOMRectReadOnly code and get rid of the virtual getters, which would be nice.
I also wasn't thrilled to put the DOMMatrix setters on the DOMMatrixReadOnly
class, but for brevity and simplicity of implementation, I've made them
public. I briefly considered making the setters protected on the ReadOnly
version of the class, but I'm not convinced that having to explicitly make
them public on the derived class is worth the extra copies of the names.

I can land the removal behind a pref first if you want and all that instead.
Again, this doesn't remove the internal usage for getComputedStyle (yet).
