Previously we were ignoring the actual parameters and setting the arity
to an incorrect value, which could cause crashes (or unexpected traps).

For some reason, I've used 'Ali.mpfard' as opposed to 'ali.mpfard'.
This maps that email to my serenityos email :P

And let's make them red too, to help us notice them. :^)

Some icons only exist in 16x16 and we should still allow them to be
loaded via the LibGUI default icon system.
This patch also reimplements GUI::default_icon() as a MUST() wrapper
around try_create_default_icon().

Print the full associated string metadata by default (if available.)

The document describes the implications of enabling and disabling that
option on the ability to enable SMP mode, and describes the requirements
for enabling IOAPIC mode even without enabling SMP mode.
|
|
We need to use the IOAPIC in SMP mode, so if the user requested to
disable it, we can't enable SMP mode either.

This is largely copied from the `man` man page, since the same
information applies.
|
|
This fixes the problem before, where searching "Shell" would list
"Shell-vars" in the results, but searching "Shell-vars" would make it
disappear.
Also removed some now-unnecessary includes.

I found it strange that `man` and `Help` did not accept the same command
line arguments since they are so similar. So... now they do. :^)
This means you can now open for example the `tar` man page in Help with
`Help tar`, or `Help 1 tar` if you want to disambiguate between pages in
different sections.
If the result is not found, it falls back to the previous behavior,
treating the input as a search query.
Initially I had this written as two optional positional arguments, but
when told to parse `[optional int] [optional string]`, and then given a
string input, ArgsParser forwards it to the [optional int], which then
fails to parse. Ideally it would pass it to the second, [optional
string] arg instead, but that looks like a fairly big change to make to
ArgsParser's internals, and risk breaking things. Maybe this ugly hack
will be an incentive to fix it. :^)

These two lambdas are always called together, in this order, so why not
make them one instead?
Also converted a couple of west-consts to east-const.
|
|
Previously, launching Help with a query like `Help tar` left the page
blank, which looks like something has gone wrong. Instead, let's show
the usual welcome page.

Based on what characters Windows 10 wrote when a key was pressed.
This makes it a lot nicer to use a Danish keyboard :^)

This patch adds a 512 frame timeline to Magnifier and the ability to
step through it with the arrow keys.
This makes it easier to check Serenity animations frame by frame for
correctness etc.

MacOS ships with an out of date ncurses that can't properly generate
terminfo from the newer source code. This change checks for a valid
`tic` executable of the proper version, first in PATH and then in
the Homebrew cellar if brew is installed. Otherwise it aborts
installation.
See comment in the code as well as the following for details:

When cp fails, now it prints an error string (strerror)
instead of an error code.

Before, `SoftwareRasterizer` was iterating over all 32 possible texture
units for each fragment and checking each if they're bound to a texture.
After this change, an intrusive list containing only texture units with
bound textures is passed to the rasterizer. In GLQuake, this results in
a performance improvement of ~30% (from 12 to 16 FPS in the first demo)
on my machine.
|
|
This smaller block size allows us to use an `u8` for the pixel mask
during triangle rasterization. These changes result in better FPS in
3DFileViewer, which periodically shoots up to 250-300 FPS on my
machine. Before, the peaks were somewhere in the range of 160-170 FPS.

For setreuid and setresuid syscalls, -1 means to set the current
uid/euid/gid/egid value, to be more convenient for programming.
However, for other syscalls where we pass only one argument, there's no
justification to specify -1.
This behavior is identical to how Linux handles the value -1, and is
influenced by the fact that the manual pages for the group of one
argument syscalls that handle ID operations is ambiguous about this
topic.

Previously we multiplied the interpolated texture coordinates by
width - 1 and height - 1 instead of width and height which resulted in
some wrongly mapped textures, especially visible in the glquake light
maps.
This also corrects the wrap mode being wrongly swapped for s/t
coordinates.
Since we do not have texture borders implemented yet we always use
GL_CLAMP_TO_EDGE for all clamping wrap modes for the time being.

Now it returns `Failure` value via `exit`, and the caller is
responsible of reporting errors to the user.

Unsurprisingly, the /proc/PID/stacks/TID stack walk had the same
arbitrary memory read problem as the perf event stack walk.
It would be nice if the kernel had a single stack walk implementation,
but that's outside the scope of this commit.
|

Since perfcore files can be generated during process finalization,
we can't just allow them to contain sensitive kernel information
if they're gonna be owned by the process's own UID+GID.
So instead, perfcores are now owned by 0:0. This is not the most
ergonomic solution, but I'm not sure what we could do to make it nicer.
We'll have to think more about that. In the meantime, this patches up
a kernel info leak. :^)
