53db492aba Base: Rename the "html" test directory to "www" 
It was conflicting with the html program and I'm too lazy to deal with
that right now. :^)

d481ae95b5 Kernel: Defer creation of Region CoW bitmaps until they're needed 
Instead of allocating and populating a Copy-on-Write bitmap for each
Region up front, wait until we actually clone the Region for sharing
with another process.

In most cases, we never need any CoW bits and we save ourselves a lot
of kmalloc() memory and time.

9e7560fae9 AK: Make Bitmap constructors public to allow make<Bitmap>() 
I don't love this, but I also don't love the Bitmap class in general.

c58d1868cb Kernel: Fix munmap() bad splitting of already-split Regions 
When splitting an Region that's already the result of an earlier split,
we have to take the Region's offset-in-VMObject into account since it
may be non-zero.

08a1fb8f1a LibGUI+PaintBrush: Fix to GFilePicker and PaintBrush enhancements. 
GFilePicker
- Fixed GFilePicker to use new ref-counted construct method to stop crashing on open dialog.
  - PaintBrush is still crashing on open dialog due to an unrelated issue.

PaintBrush
- Created 16x16 icon for PaintBrush
- Moved Open option into App menu.
- Changed help menu to make use of the standardized About dialog.

a5e5a3fab7 LibHTML: Implement basic support for inline style attributes 
You can now style elements with inline styles:

    <div style="color: #ff0000">This is red!</div>

Pretty neat :^)

ac20919b13 Kernel: Make it possible to turn off VM guard pages at compile time 
This might be useful for debugging since guard pages introduce a fair
amount of noise in the virtual address space.

8e775d241e Kernel: Make DiskBackedFS flush writes if cache is completely dirty 
If we want to make a new entry in the disk cache when it's completely
full of dirty blocks, we'll now synchronously flush the writes at that
point. Maybe it's not ideal, but at least we can keep going.

922fd703c9 Kernel: Convert the DiskBackedFS write API to take "const u8*" 
This way clients are not required to have instantiated ByteBuffers
and can choose whatever memory scheme works best for them.

Also converted some of the Ext2FS code to use stack buffers instead.

1fc2612667 Kernel: Make DiskBackedFS::read_block() write to client-provided memory 
Instead of having DiskBackedFS allocate a ByteBuffer, leave it to each
client to provide buffer space.

This is significantly faster in many cases where we can use a stack
buffer and avoid heap allocation entirely.

a61f6ccc27 Kernel: Implement a simpler, bigger cache for DiskBackedFS 
The hashmap cache was ridiculously slow and hurt us more than it helped
us. This patch replaces it with a flat memory cache that keeps up to
10'000 blocks in cache with a simple dirty bit.

The syncd task will wake up periodically and call flush_writes() on all
file systems, which now causes us to traverse the cache and write all
dirty blocks to disk.

There's a ton of room for improvement here, but this itself is already
drastically better when doing repeated GCC invocations.

from the parent element.

elements.
