e31dac3ba4 Lagom: Build LibJS + "js" test program 
You can now get a full Linux build of the "js" test program by simply
building in Meta/Lagom :^)

Well that was easy. LibJS can now run on Linux :^)

538537dfd0 LibJS: Use rand() for Math.random() on other systems 
I bet we could be smarter here and use arc4random() on systems where
it is present. I'm not sure how to detect it though.

6f235ad93f LibWeb: Implement cancelAnimationFrame() 
These functions (rAF and cAF) should eventually stop using raw ID's
from GUI::DisplayLink as their identifiers. That's a FIXME for now. :^)

Andreas Kling
39045bfde8 LibWeb: Add basic support for requestAnimationFrame() 
We now support rAF, driven by GUI::DisplayLink callbacks. It's a bit
strange how we keep registering new callbacks over and over.
That's something we can definitely optimize.

This allows you to update animations/whatever without doing it more
often than the browser can display.

424a3f5ac3 WindowServer+LibGUI: Add a way to get notified at display refresh rate 
This patch adds GUI::DisplayLink, a mechanism for registering callbacks
that will fire at the display refresh rate.

Note that we don't actually know the screen refresh rate, but this is
instead completely driven by WindowServer's compositing timer. For all
current intents and purposes it does the job well enough. :^)

7309642ca8 LibWeb: Use FlyString for Element tag names 
This makes selector matching a lot more efficient, and also reduces the
number of strings on the heap.

cccbe43056 LibJS: Use FlyString for identifiers 
This makes variable and property lookups a lot faster since comparing
two FlyStrings is O(1).

4f72f6b886 AK: Add FlyString, a simple flyweight string class 
FlyString is a flyweight string class that wraps a RefPtr<StringImpl>
known to be unique among the set of FlyStrings. The class is very
unoptimized at the moment.

When to use FlyString:

- When you want O(1) string comparison
- When you want to deduplicate a lot of identical strings

When not to use FlyString:

- For strings that don't need either of the above features
- For strings that are likely to be unique

d0629d0a8c Shell: More general tilde expansion 
Now expanding a tilde isn't hardcoded to just work for `cd`. It is instead
expanded while processing shell arguments. Autocompletion still doesn't
work, but this is definitely an improvement over the last iteration.

1ef3d4af69 Shell: Use starts_with() in expand_parameters

d806dfe801 Shell: Use size_t for SH_DEBUG vector iteration 
We missed this when switching to size_t for vector sizing as this
code is not normally compiled.

ec6e55cfc6 LibGUI: Don't spam WindowServer with SetWindowOverrideCursor messages 
Remember the override cursor in GUI::Window and avoid sending a message
to WindowServer when possible.

This removes a lot of synchronous IPC between Browser and WindowServer,
which noticeably improves DOM event responsiveness. :^)

e2a38f3aba LibWeb: Add a naive implementation of setInterval() 
This implementation leaks a Core::Timer whenever you call setInterval()
so it will definitely need some improvements, but it does kinda work!

7c48c3c8e1 LibJS: Parse "if" statements 
This patch implements basic parsing of "if" statements. We don't yet
support parsing "else", so I added a FIXME about that.

4dde36844b LibWeb: Add a DOM Event class (instead of events being simple strings) 
This patch adds the Event base class, along with a MouseEvent subclass.
We now dispatch MouseEvent objects for mousedown, mouseup and mousemove
and these objects have the .offsetX and .offsetY properties.

Both of those properties are hard-coded at the moment. This will be
fixed in the next patch. :^)

324b92fd06 LibJS: Virtualize access to an Object's own properties 
Object now has virtual get_own_property() and put_own_property() member
functions that can be overridden to provide custom behavior.

We use these virtuals to move Array-specific access behavior to Array.

00feef8642 LibJS: Some optimizations for ObjectExpression 
- move() the property map when constructing ObjectExpression instead of
  making a copy.
- Use key+value iterators to traverse the property map in the execute()
  and dump() functions.

bceabd7c4b LibJS: Add ArrayPrototype and implement Array.prototype.push() 
This function is ultimately supposed to be generic and allow any |this|
that has a length property, but for now it only works on our own Array
object type.
