421a340572 Piano: Make decay more accurate
1. Make decay sample-granular rather than buffer-granular
You only have ~43 buffers per second which can make a jagged signal.

2. Calculate decay in milliseconds
Decay is supposed to be a time value.

44c81ee9db Piano: Remove phony multiple same note playback
I say "phony" because it's not actually playing the same frequency
twice, it's just playing the same frequency at a higher volume. We can
properly implement this later but at the moment it'll get in the way of
our ADSR implementation.

f909095981 Piano: Fix default knob values
Now you can change the defaults in AudioEngine and not be totally
confused.

1. The default for m_octave_knob was actually upside-down.
2. The default for m_decay_knob wasn't respecting AudioEngine.
3. The default for m_delay_knob wasn't respecting AudioEngine.

47978a5828 Kernel: Add support for vmmouse
We add this feature together with the VMWareBackdoor class.
VMWareBackdoor class is responsible for enabling the vmmouse, and then
controlling it from the PS2 mouse IRQ handler.

44ddfd2bf5 WindowServer: Fix the drain mouse mechanism
Now we actually check if the Mouse packet relative flag is enabled or
not.
In addition to that, we have debug messages for mouse point changes.

3969fcc72e build-root-filesystem.sh: Set umask to 0022
On my system (Void Linux) the root user has a default umask of 0077,
causing files and directories in the disk image to have zero group and
world permissions.

c600280dde AK: The <cxxabi.h> header is not available during Toolchain build
This will need some refinement, but basically since we build LibC
during the toolchain build, we don't have libstdc++ headers yet.

9dc78338ad ProfileViewer: Only show live allocations by default
For memory profiles, we now keep track of which allocations are still
live at the end of the selected timeline range and only show those.

This is really cool, I have to admit. :^)

266d7ca268 ProfileViewer: Add basic support for loading "perfcore" files
"perfcore" is the file that the kernel generates after a process that
was recording performance events has exited.

This patch teaches ProfileViewer how to load (and symbolicate!) those
files so that we can look at them. This will need a bunch more work
to make it truly useful.

fa97ff1c83 LibC: Allow opting into malloc() and free() performance event logging
If a program is started with LIBC_PROFILE_MALLOC in the environment,
it will now generate PERF_EVENT_MALLOC and PERF_EVENT_FREE.

3879e5b9d4 Kernel: Start working on a syscall for logging performance events
This patch introduces sys$perf_event() with two event types:

- PERF_EVENT_MALLOC
- PERF_EVENT_FREE

After the first call to sys$perf_event(), a process will begin keeping
these events in a buffer. When the process dies, that buffer will be
written out to "perfcore" in the current directory unless that filename
is already taken.

This is probably not the best way to do this, but it's a start and will
make it possible to start doing memory allocation profiling. :^)

2d39da5405 LibCore: Put all classes in the Core namespace and remove the leading C
I've been wanting to do this for a long time. It's time we start being
consistent about how this stuff works.

The new convention is:

- "LibFoo" is a userspace library that provides the "Foo" namespace.

That's it :^) This was pretty tedious to convert and I didn't even
start on LibGUI yet. But it's coming up next.

f9609fe08a Userland: useradd utility
This commit implements the `useradd` utility that is found on most,
if not all *NIX systems. It allows the root user to add new users
to the password file found in `/etc/passwd`, thereby making
it easier to manipulate the file.

dfaa5ecf81 LibC: Implement append modes for fopen()
Previously, `fopen()` didn't contain an implementation for the
append modes, even though the Kernel supports it via `O_APPEND`.

This patch rectifies that by implementing them so an assert is
no longer thrown.

cdbdd397db LibC: Move FILE definition to bits/FILE.h
There are some headers in libc that require us to have definitions,
such as `FILE` available to us (such as in `pwd.h`). It is bad
practice to include the entirety of `stdio.h`, so it makes more
sense to put `FILE` into it's own header.

5b47b0d867 LibGUI: Make GAction scoped to its CObject parent (widget or window)
Unparented GActions are still parented to the application like before,
making them globally available.

This makes it possible to have actions that work whenever a specific
window is active, no matter which widget is currently focused. :^)

998765a7a6 LibC: The exec() family of functions should not search "." by default
We should only execute the filename verbatim if it contains a slash (/)
character somewhere. Otherwise, we need to look through the entries in
the PATH environment variable.

This fixes an issue where you could easily "override" system programs
by placing them in a directory you control, and then waiting for
someone to come there and run e.g "ls" :^)
