b8cf83926a LibCore: Add a basic Core::DateTime class
This is just to have a pleasant way to print the current time for now:

    dbg() << Core::DateTime::now();

Or if you want it as a string:

    Core::DateTime::now().to_string();

6cbd72f54f AK: Remove bitrotted Traits::dump() mechanism
This was only used by HashTable::dump() which I used when doing the
first HashTable implementation. Removing this allows us to also remove
most includes of <AK/kstdio.h>.

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.

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. :^)

9276582535 LibCore: Rewrite CArgsParser
This is a complete reimplementation of CArgsParser with a different API.

Now, CArgsParser properly supports and distinguishes between:
* Positional arguments (required or not)
* Options

Options can be short and/or long.

The API allows you to add custom option and argument types. A few types are
pre-implemented for convenience:
* Boolean options (take no value)
* String and integer options (take a required value)
* String and integer arguments
* Vector-of-string arguments

This commit doesn't include changes for all the users of CArgsParser (see next
commit for that).

72d68b4025 LibCore: Fix broken "stay_within" mechanism in event dispatch
The "stay_within" parameter to CObject::dispatch_event() optionally
specifies a node in the CObject parent chain where event dispatch
should stop bubbling upwards.

Since event dispatch is done recursively, this was not working right,
as we would simply return from the innermost dispatch loop, leaving
the event un-accepted, which meant that the penultimately inner
dispatch loop would pick up the event and keep bubbling it anyway.

This made it possible for events to jump across window boundaries
within an application, in cases where one window was a CObject ancestor
of another window. This is typically the case with dialog windows.

Fix #1078.

66598f60fe SystemMonitor: Show process unveil() state as "Veil"
A process has one of three veil states:

- None: unveil() has never been called.
- Dropped: unveil() has been called, and can be called again.
- Locked: unveil() has been called, and cannot be called again.

94ca55cefd Meta: Add license header to source files
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.

For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.

Going forward, all new source files should include a license header.

cee597a728 LibCore: Make CIODevice::read_all() actually read all data
It used to only read the data it could get without blocking. Andreas says this
was intentional, but it's counterintuitive and no code that uses read_all()
actually expects it to return only a part of the data. So change it to always
read data until an EOF (or an error) is received.

2a8de4cdec LibCore: Fix segfault in CArgsParser (#1072)
CArgsParser::parse_next_param did not properly ensure that, when
a param required a following argument, there were enough parameters left to
complete the parse. This meant that params_left could become negative,
avoiding parse_next_param's termination condition, and cause a segfault
when reading from argv with an out of bounds index.

This fixes the check to ensure that we do in fact have the right amount
of parameters and also adds an assertion to ensure that params_left does
not become negative.

50677bf806 Kernel: Refactor scheduler to use dynamic thread priorities
Threads now have numeric priorities with a base priority in the 1-99
range.

Whenever a runnable thread is *not* scheduled, its effective priority
is incremented by 1. This is tracked in Thread::m_extra_priority.
The effective priority of a thread is m_priority + m_extra_priority.

When a runnable thread *is* scheduled, its m_extra_priority is reset to
zero and the effective priority returns to base.

This means that lower-priority threads will always eventually get
scheduled to run, once its effective priority becomes high enough to
exceed the base priority of threads "above" it.

The previous values for ThreadPriority (Low, Normal and High) are now
replaced as follows:

    Low -> 10
    Normal -> 30
    High -> 50

In other words, it will take 20 ticks for a "Low" priority thread to
get to "Normal" effective priority, and another 20 to reach "High".

This is not perfect, and I've used some quite naive data structures,
but I think the mechanism will allow us to build various new and
interesting optimizations, and we can figure out better data structures
later on. :^)

up front. :^)

411d293961 LibCore+LibGUI: Don't fire timers in non-visible windows by default
LibCore timers now have a TimerShouldFireWhenNotVisible flag which is
set to "No" by default.

If "No", the timer will not be fired by the event loop if it's within
a CObject tree whose nearest GWindow ancestor is currently not visible
for timer purposes. (Specificially, this means that the window is
either minimized or fully occluded, and so does not want to fire timers
just to update the UI.)

This is another nice step towards a calm and serene operating system.

c74cde918a Kernel+SystemMonitor: Expose amount of per-process clean inode memory
This is memory that's loaded from an inode (file) but not modified in
memory, so still identical to what's on disk. This kind of memory can
be freed and reloaded transparently from disk if needed.

0d5e0e4cad Kernel+SystemMonitor: Expose amount of per-process dirty private memory
Dirty private memory is all memory in non-inode-backed mappings that's
process-private, meaning it's not shared with any other process.

This patch exposes that number via SystemMonitor, giving us an idea of
how much memory each process is responsible for all on its own.

1222b94ab8 LibCore: Allow LibCore to be compiled on macOS host
Compiling LibCore on macOS is needed if one wants to compile host tools
(like IPCCompiler) on a non Linux host.
These changes could be possibly reverted once "event loop" functionality
and "base library" (Vector, String etc.) will be split in two separate libraries,
updating all relevant projects.
