af840af1ce Documentation: Let's have a coding style document 
This is only meant to be about higher-level coding style, not the small
things like brace placement, indentation, etc. For all of that we just
obey clang-format.

de87258b4f Userland: Remove immature "tc" and "uc" programs in favor of "nc" 
The netcat-lite "nc" utility is where we should put all of the various
"lightweight" TCP/UDP client features.

5de483cfbb Kernel: Move DiskDevice::block_size() up to BlockDevice 
All block devices should have a block size, after all. This defaults to
PAGE_SIZE if no size is specified.

of an unnecessary and suspicious-looking buffer.

When the terminal app window became smaller than the longest filename,
a division by zero occured while calculating the offset.

076827a05d GModel: Rename on_model_update(GModel&) => on_update() 
Just simplifying the API of this hook a little bit.

f7dce05c82 LibGUI: Remove confusing GModelNotification concept 
This was a bad idea and it didn't stick. Instead we should just use the
simple "on_foo" hook functions like we do for everything else. :^)

4f3234148a Inspector: Show remote object properties in a table view 
This patch expands the object model of this program quite a bit.
We now have a RemoteProcess object that contains a list of remote root
RemoteObject objects.

The RemoteProcess vends a RemoteObjectGraphModel&, and indices in that
model have internal_data() pointing to a corresponding RemoteObject.
RemoteObjects in turn vend a RemoteObjectPropertyModel&, which is what
we use to show the object properties.

This is pretty cool :^)

64f16c141d Terminal: Implement basic history scrollback 
This code needs some optimization work to reduce the amount of repaints
but the history feature basically works, which is cool :^)

Fixes #431.

462336ed49 LibVT: Add scrollback history to VT::Terminal 
The default (hard-coded) history size is 500 lines. When the history is
altered, the TerminalClient is notified via terminal_history_changed().

a5cdd0afa5 NonnullPtrVector: Add ptr_at() getters for accessing the NonnullPtr 
Normally you want to access the T&, but sometimes you need to grab at
the NonnullPtr, for example when moving it out of the Vector before
a call to remove(). This is generally a weird pattern, but I don't have
a better solution at the moment.

6cd9c020ea LibC: Write to the dbg() every time we perror() in userspace 
There's a high chance that we're interested in whatever errors come out
of perror(), so let's output those on the debugger as well.

91c79440a1 Userland: Improved the printing of the ls command. (#468) 
The ls command takes into consideration the length of the largest
filename when it prints a line.

c2213449c0 LibCore: Move CObject serialization into CObject::save_to(JsonObject&) 
The idea is for subclasses to override this and add whatever properties
are relevant for them, then call up to their base class, etc.

7038935f74 GraphicsBitmap: create_wrapper() should take pitch as a parameter 
We shouldn't assume that the pitch of some arbitrary bitmap memory that
we're wrapping is going to be 16-byte aligned. Instead, just take the
pitch as a parameter.

Also update WindowServer to pass the pitch to the framebuffer bitmaps.

d11d847161 WindowServer: Fix an assertion 
Now that the window used by a WSMenu is its child CObject, the menu also
receives CChildEvent's about the window, including CEvent::ChildAdded when
the window gets created. At this point, menu_window() still returns nullptr,
so stop unconditionally assuming that it doesn't. We should not care whether
or not we have a window for unrelated events anyway.

acccf9ccda Kernel: Move device lookup to Device class itself 
Previously, VFS stored a list of all devices, and devices had to
register and unregister themselves with it. This cleans up things
a bit.

d5352b87b7 AudioServer: Turn ASMixer into a CObject 
It was wrongly inheriting from RefCounted<AudioServer> without using
reference counting. Let's just make it a CObject instead.

1b3599fbbc LibCore: Make CSocket's notifiers into children of the CSocket 
The Inspector app quickly exposes crappy flat object hiearchies without
parent/child relationships. This is one of many commits that improves
the situation by making parent/child CObject relationships explicit.

9d57e7ed68 WindowServer: Tell WSWindows who their CObject parent is 
Instead of using a weird "internal owner" pointer, just set the owning
object as the CObject::parent of WSWindow.

05cd178477 Inspector: Add a GUI tool for viewing a remote process's CObject graph 
Here comes the foundation for a neat remote debugging tool.

Right now, it connects to a remote process's CEventLoop RPC socket and
retreives the remote object graph JSON dump. The remote object graph
is then reconstructed and exposed through a GModel subclass, which is
then displayed in a GTreeView.

It's pretty cool, I think. :^)

5c7bb09a73 GTreeView: Support multiple root-level items 
Previously it was only possible to have a single root-level item in a
GTreeView. This was an oversight and I didn't realize it because this
code was only ever used in the FileManager, which has one root ("/").

Also factored out item toggling into a separate function, and increase
the base indentation level so that root items can be toggled as well.

Finally, let the user toggle the selected item with the spacebar. :^)

f6cb2fd2fb GModel: Have create_index() take a const void* 
This is just for convenience really. It lets you skip const_casting in
all the code that calls this API, which you would basically always be
doing otherwise.
