d19136ce07 AWavLoader: Share code between 24/16/8 bit reading
The only part of this that actually differs between all of them is the
stream -> sample reading, so turn that into a function that the channel
reader can call as it wants.

bf8d72f5a4 Kernel: Remove unnecessary use of LibDraw.
BXVGADevice was using a Size object for its framebuffer size. We shouldn't
be pulling in userspace code in the kernel like this, even if it's just
headers. :^)

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. :^)

b907608e46 SharedBuffer: Split the creation and share steps
This allows us to seal a buffer *before* anyone else has access to it
(well, ok, the creating process still does, but you can't win them all).

It also means that a SharedBuffer can be shared with multiple clients:
all you need is to have access to it to share it on again.

f60d7e5d1f JsonValue: Add to_uint(), to_int() and as_double().
The to_foo() functions are for converting when you might not be sure of the
underlying value type. The as_foo() family assumes that you know exactly
what the underlying value type is.

7a53096e8d LibGUI: Revert GWindowServerConnection to being a singleton
This was a mistake, of course. Nested event loops don't need (or want)
independent server connections.

We initialize the connection early in GEventLoop for e.g. users that
want to get the size of a GDesktop before the connection has been
established.

Bug noticed by Andreas, introduced by me ;-)

9c8dd836fc Rename new IPC headers & classes
Sticking these in a namespace allows us to use a more generic
("Connection") term without clashing, which is way easier to understand
than to try to come up with unique names for both.

2177594c96 Port LibGUI to use CIPCClientSideConnection
As a consequence, move to use an explicit handshake() method rather than
calling virtuals from the constructor. This seemed to not bother
AClientConnection, but LibGUI crashes (rightfully) because of it.

3837de0573 WSEventLoop: Remove inheritance from CEventLoop
The only reason for the inheritance was to add FDs to the select set.

Since CNotifier is available (and now also quite useful), we can make use of it
instead, and remove the inheritance.

10ffaf019f Kernel: Initial FDC Device Driver (#315)
A basic Floppy Disk Controller device driver for any system later than (and including) the IBM AT. The driver is based on the documentation supplied by QEMU, which is the datasheet for the Intel 82078 Floppy Disk controller (found here: https://wiki.qemu.org/images/f/f0/29047403.pdf)

Naturally, floppy disks are a _very_ outdated storage medium, however, as Serenity is a throwback to aesthetic 90s computing, it's a definite must have. Not to mention that there are still a lot of floppy disks around, with countless petabytes of software on them, so it would be nice if people could create images of said disks with serenity.

The code for this is mostly clean. however there are a LOT of values specified in the datasheet, so some of them might be wrong, not to mention that the actual specification itself is rather dirt and seemingly hacked together.

I'm also only supporting 3.5" floppy disks, without PIO polling (DMA only), so if you want anything more/less than 1.44MB HD Floppys, you'll have to do it yourself.

4f94fbc9e1 Kernel: Split SCHEDULER_DEBUG into a new SCHEDULER_RUNNABLE_DEBUG
And use dbgprintf() consistently on a few of the pieces of logging here.

This is useful when trying to track thread switching when you don't
really care about what it's switching _to_.

a648331e26 Kernel: Fix a nasty lock bug with exec()
Exec doesn't leave through the syscall handler, so it didn't unlock the
big_lock. This means that reentering can lock it again, and then another
thread could endlessly yield waiting to acquire the lock (futilely).

This fixes AudioServer using 100% CPU.

2df6f0e87f Work on AudioServer
The center of this is now an ABuffer class in LibAudio.
ABuffer contains ASample, which has two channels (left/right) in
floating point for mixing purposes, in 44100hz.

This means that the loaders (AWavLoader in this case) needs to do some
manipulation to get things in the right format, but that we don't need
to care after format loading is done.

While we're at it, do some correctness fixes. PCM data is unsigned if
it's 8 bit, but 16 bit is signed. And /dev/audio also wants signed 16
bit audio, so give it what it wants.

On top of this, AudioServer now accepts requests to play a buffer.
The IPC mechanism here is pretty much a 1:1 copy-paste from
LibGUI/WindowServer. It can be generalized more in the future, but for
now I want to get AudioServer working decently first :)

Additionally, add a little "aplay" tool to load and play a WAV file. It
will break with large WAVs (run out of memory, heh...) but it's a start.

Future work needs to make AudioServer block buffer submission from
clients until it has played the buffer they are requesting to play.

a17fbd98e7 LibGUI: Add input types to GMessageBox.
Currently the two available input types are:

- GMessageBox::InputType::OK (default)
- GMessageBox::InputType::OKCancel

Based on your choice, GMessageBox::exec() will return ExecOK or ExecCancel.

f98b1f635b SystemDialog: Add a new app for showing system dialogs.
Currently this will be used by the WindowServer to show some dialogs.
This is needed since WindowServer can't use LibGUI and reimplementing
message box functionality inside WindowServer would be silly. :^)

The only dialog supported in this initial version is --shutdown

a714fc661d LibCore: Add a way to mark a socket as blocking (or not)
If custom I/O is being done outside CIODevice, we need a way to force blocking sometimes.
This also fixes the default of CLocalSocket to be non-blocking, the same
as CTCPSocket.

6aa77d1999 SharedBuffer: Fix deadlock on destroy
We were locking the list of references, and then destroying the
reference, which made things go a little crazy.

It's more straightforward to just remove the per-reference lock: the
syscalls all have to lock the full list anyway, so let's just do that
and avoid the hassle.

While I'm at it, also move the SharedBuffer code out to its own file as it's
getting a little long and unwieldly, and Process.cpp is already huge.

3dac1f8ac5 Kernel: Remove use of [[gnu::pure]].
I was messing around with this to tell the compiler that these functions
always return the same value no matter how many times you call them.

It doesn't really seem to improve code generation and it looks weird so
let's just get rid of it.
