f511421aaa Kernel+ProcessManager: Add some more info to /proc/PID/fds 
- "seekable": whether the fd is seekable or sequential.
- "class": which kernel C++ class implements this File.
- "offset": the current implicit POSIX API file offset.

8a703c0076 ProcessManager: Add a new per-proces "open files" view showing open FDs 
This uses the data from /proc/PID/fds with ease now that it's JSON. :^)

e8b3a539b4 ProcessManager: Fix timer leak in ProcessStacksWidget 
CObjects should really be reference-counted instead of this error-prone
(but convenient) model.

Found by PVS-Studio.

5ded77df39 Kernel+ProcessManager: Let processes have an icon and show it in the table. 
Processes can now have an icon assigned, which is essentially a 16x16 RGBA32
bitmap exposed as a shared buffer ID.

You set the icon ID by calling set_process_icon(int) and the icon ID will be
exposed through /proc/all.

To make this work, I added a mechanism for making shared buffers globally
accessible. For safety reasons, each app seals the icon buffer before making
it global.

Right now the first call to GWindow::set_icon() is what determines the
process icon. We'll probably change this in the future. :^)

cf57d64481 ProcessManager: Add a "Memory map" view to show a process's VM layout. 
Fetch all the data from /proc/PID/vm for the selected process and show it
in a nice GTableView. :^)

841b2e5d13 WindowServer+LibGUI: Pass window icons as shared buffers rather than paths. 
Now that we support more than 2 clients per shared buffer, we can use them
for window icons. I didn't do that previously since it would have made the
Taskbar process unable to access the icons.

This opens up some nice possibilities for programmatically generated icons.

34ccc7b4a7 ProcessManager: Oops, the process-specific view should not be global. 
It should only be visible when we have the process table open.

9b7e1eb287 ProcessManager: Add a process-specific tab view below the process table. 
To start out, add a "Stacks" view where we see what the selected process is
currently doing (via /proc/PID/stack) :^)

c452528952 ProcessManager: Add ProcessTableView::on_process_selected() callback. 
This will be useful for doing something in response to the user selecting
a different process.

185ba4dc3f ProcessManager: Move the memory stats widget under "Graphs" instead. 
Making space for some new thingy under the process table view.

93489fbc4c Convert HashMap<Key, OwnPtr<T>> to HashMap<Key, NonnullOwnPtr<T>>. 
In every case I found, we never wanted to support null entry values.
With NonnullOwnPtr, we can encode that at the type level. :^)

72a3f69df7 LibGUI: Get rid of GWindow::should_exit_event_loop_on_close(). 
This behavior and API was extremely counter-intuitive since our default
behavior was for applications to never exit after you close all of their
windows.

Now that we exit the event loop by default when the very last GWindow is
deleted, we don't have to worry about this.

aa2224a2f0 GWidget: Add set_preferred_size(width, height) overload. 
It was annoying to always write set_preferred_size({ width, height }). :^)

1c0669f010 LibDraw: Introduce (formerly known as SharedGraphics.) 
Instead of LibGUI and WindowServer building their own copies of the drawing
and graphics code, let's it in a separate LibDraw library.

This avoids building the code twice, and will encourage better separation
of concerns. :^)

245ae479eb ProcessManager: Use CProcessStatisticsReader to get process data. 
It was silly to duplicate this functionality in so many places. Now everyone
uses CProcessStatisticsReader to parse /proc/all :^)

27f699ef0c AK: Rename the common integer typedefs to make it obvious what they are. 
These types can be picked up by including <AK/Types.h>:

* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

b79112e6d6 AK: Add String::number() for creating a String from a number. 
Instead of manually doing String::format("%d"/"%u") everywhere, let's have
a String API for this. It's just a wrapper around format() for now, but it
could be made more efficient in the future.

315716d193 GUI: Use Win2K-like "warm gray" color instead of the older colder gray. 
Someone suggested this a long time ago and I never got around to it.
So here we go, here's the warm gray! I have to admit I like it better. :^)

2bd8118843 Kernel: Change the format of /proc/all to JSON. 
Update ProcessManager, top and WSCPUMonitor to handle the new format.

Since the kernel is not allowed to use floating-point math, we now compile
the JSON classes in AK without JsonValue::Type::Double support.
To accomodate large unsigned ints, I added a JsonValue::Type::UnsignedInt.

f0a6b42066 Move common Application build steps into their own Makefile.common 
Further consolidation is of course possible, eg the Games/ programs
follow the same rules more or less.

0ed89440f1 ProcessManager+top: Rename "linear" size to "virtual" size. 
I originally called it "linear" because that's how the Intel manual names
virtual addresses in many cases. I'm ready to accept that most people know
this as "virtual" so let's just call it that.

0dc9af5f7e Add clang-format file 
Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.

1598a0a5cb ProcessManager: Draw the graphs as lines. 
This looks pretty neat. Also it exercises the diagonal line drawing code
so we get 2-for-1. :^)

This means it won't hog the CPU for more than a single timeslice. :^)

5eedb22834 Sprinkle use of AK::Vector in various places. 
Some of these are less helpful than others. Avoiding a bunch of mallocs
in the event loop wakeup code is definitely nice.

301a269ca0 Get rid of SERENITY macro since the compiler already defines __serenity__
