Note that this patch also replaces legacy VK_* with KEY_*, and replaces
synthesizeKey() for inputting some characters with sendString() because
it's better and clearer what it does and it sets shiftKey state properly.

Now, callers of EventUtils.synthesizeKey() don't need to specify
KeyboardEvent.code value anymore if they assume that active keyboard layout
is US keyboard layout.
Note that this patch changes the meaning of only test_bug551434.html.
Some callers in it don't match the key value and code value but that looks
like that they don't checking such odd keyboard events. So, they must be
bug of the test.

This patch does a minor refactor of the code used to style popup menu for
the <select> element.
It improves the custom styling experience on MacOS, preserves the functionality
on Windows and removes the unnecessary per-item CSS rules significantly
improving the performance of opening the <select> list.

Also, we only care about the properties that we support and that are animatable, as the non-animatable ones do not generate transitionend events

Since the order of events is 'blur' followed by 'focus', we send a message from the content process to the parent process and wait for a reply to give enough time for the parent process to signal that the 'blur' was related to the focusing of the search field. If the parent process hasn't signaled as such, then the content process will proceed with hiding the dropdown.

This reduces the amount of places where we need to specify the mozilla/frame-script environment. It does have
the side effect of allowing those globals in the whole file, but that is what specifying the environment would
do, and this is also for mochitest test files only.

The comparison being removed was only put in place because it seemed like a "good-idea" to prevent <select> from being unreadable, though it's not a fool-proof strategy and it breaks content that uses different styling approaches. This removal does not regress any of the other test cases.

This patch also fixes a bug in our UpdateDropDown code where we weren't computing updated styles for <select> element, as well as another bug where we weren't passing the correct number of arguments to this.populate.
