This adds a scale factor to Painter, which will be used for HighDPI
support. It's also a step towards general affine transforms on Painters.
All of Painter's public API takes logical coordinates, while some
internals deal with physical coordinates now. If scale == 1, logical
and physical coordinates are the same. For scale == 2, a 200x100 bitmap
would be covered by a logical {0, 0, 100, 50} rect, while its physical
size would be {0, 0, 200, 100}.
Most of Painter's functions just assert that scale() == 1 is for now,
but most functions called by WindowServer are updated to handle
arbitrary (integer) scale.
Also add a new Demo "LibGfxScaleDemo" that covers the converted
functions and that can be used to iteratively add scaling support
to more functions.
To make Painter's interface deal with logical coordinates only,
make translation() and clip_rect() non-public.

The underlying fill_rect() works correctly, but the special case for
thickness = 1 was not blending the new color with the target pixel's
color, causing RGBA colors to be painted as their RGB counterpart.

Fixes #4905

There's no reason to have this, and it will most likely fail anyway
(since there's likely no /tmp/rpc).

Problem:
- Many constructors are defined as `{}` rather than using the ` =
default` compiler-provided constructor.
- Some types provide an implicit conversion operator from `nullptr_t`
instead of requiring the caller to default construct. This violates
the C++ Core Guidelines suggestion to declare single-argument
constructors explicit
(https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#c46-by-default-declare-single-argument-constructors-explicit).
Solution:
- Change default constructors to use the compiler-provided default
constructor.
- Remove implicit conversion operators from `nullptr_t` and change
usage to enforce type consistency without conversion.

Problem:
- We were using some incorrect format strings in printf-functions:
* "%7lu" to print `size_t` values instead of "%7zu";
* "%7i" to print `unsigned int` values instead of "%7u".
Solution:
- Use out(), outln() and warnln() instead of printf-functions. :^)

`unsigned int` -> `unsigned`.
Use brace initialisers instead of equal initialisers for struct members.
Prefix global variables with `g_`.
Wrap multi-line statements in curly braces.
Also:
Use const references instead of references when possible.
Rename `file_name` to `file_specifier`: "-" is not a file name.
Rename `files` to `file_specifiers`.
Avoid some useless checks.

The vast majority of programs don't ever need to use sys$ptrace(),
and it seems like a high-value system call to prevent a compromised
process from using.
This patch moves sys$ptrace() from the "proc" promise to its own,
new "ptrace" promise and updates the affected apps.

Let's adapt this class a bit better to how it's actually being used.
Instead of having valid/invalid states and storing an error in case
it's invalid, a MappedFile is now always valid, and the factory
function that creates it will return an OSError if mapping fails.

This leaves us with a total pledge of "stdio" when writing to
/etc/passwd and /etc/shadow which is kinda neat. :^)
|

There's not much work left to do at this point, but let's be strict.

Not sure why we hadn't done this one sooner, seems like a high-value
program to pledge.

Once we have /etc/passwd and /etc/shadow open for writing, there's no
need for passwd to continue running as root.
We can also drop a bunch of pledge promises, further tightening things.
|
|
This patch moves the user account password hashes from /etc/passwd,
where they were world-readable, to /etc/shadow, where only root can
access them.
The Core::Account class is extended to support both authentication
against, and modification of /etc/shadow.
The default password for "anon" as of this commit is "foo" :^)

AT_SECURE is set in the auxiliary vector when we execute setuid/setgid
programs.
In those cases, we do not want to read environment variables that
influence the logic of the dynamic loader, as they can be controlled
by the user.
|
|
DebugSession now makes the loader stop after loading the libraries,
and parses the loaded libraries of the program before continuing its
execution.
DebugSession now also supports inserting a breakpoint at a given symbol
or source position.
Additionally, DebugInfo now takes the base address of its object into
consideration.

Linux accepts both -r and -R, but the BSDs only like -R, and
dR POSIX also only mentions -R. So make -R the canonical flag.
Keep -r available as an alias for -R.

These do not crash the process anymore.

TL;DR: Like clang-format but for GML files :^)
It takes a list of files (or reads from standard input if none is given),
formats them and prints the result to standard output or writes back to
the file when using the -i/--inplace option.
