1682f0b760 Everything: Move to SPDX license identifiers in all files. 
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

0d934fc991 Kernel::CPU: Move headers into common directory 
Alot of code is shared between i386/i686/x86 and x86_64
and a lot probably will be used for compatability modes.
So we start by moving the headers into one Directory.
We will probalby be able to move some cpp files aswell.

84a399de5d Kernel: Move Kernel CommandLine parsing to strongly typed API. 
Previously all of the CommandLine parsing was spread out around the
Kernel. Instead move it all into the Kernel CommandLine class, and
expose a strongly typed API for querying the state of options.

7cf0c7cc0d Meta: Split debug defines into multiple headers. 
The following script was used to make these changes:

    #!/bin/bash
    set -e

    tmp=$(mktemp -d)

    echo "tmp=$tmp"

    find Kernel \( -name '*.cpp' -o -name '*.h' \) | sort > $tmp/Kernel.files

    cat $tmp/Kernel.files | xargs grep -Eho '[A-Z0-9_]+_DEBUG' | sort | uniq > $tmp/Kernel.macros

8465683dcf Everywhere: Debug macros instead of constexpr. 
This was done with the following script:

    find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/dbgln<debug_([a-z_]+)>/dbgln<\U\1_DEBUG>/' {} \;

acdcf59a33 Everywhere: Remove unnecessary debug comments. 
It would be tempting to uncomment these statements, but that won't work
with the new changes.

This was done with the following commands:

    find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec awk -i inplace '$0 !~ /\/\/#define/ { if (!toggle) { print; } else { toggle = !toggle } } ; $0 ~/\/\/#define/ { toggle = 1 }' {} \;

    find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec awk -i inplace '$0 !~ /\/\/ #define/ { if (!toggle) { print; } else { toggle = !toggle } } ; $0 ~/\/\/ #define/ { toggle = 1 }' {} \;

1a3a0836c0 Everywhere: Use CMake to generate AK/Debug.h. 
This was done with the help of several scripts, I dump them here to
easily find them later:

    awk '/#ifdef/ { print "#cmakedefine01 "$2 }' AK/Debug.h.in

    for debug_macro in $(awk '/#ifdef/ { print $2 }' AK/Debug.h.in)
    do
        find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/#ifdef '$debug_macro'/#if '$debug_macro'/' {} \;
    done

    # Remember to remove WRAPPER_GERNERATOR_DEBUG from the list.
    awk '/#cmake/ { print "set("$2" ON)" }' AK/Debug.h.in

d89582880e Kernel: Switch singletons to use new Singleton class 
MemoryManager cannot use the Singleton class because
MemoryManager::initialize is called before the global constructors
are run. That caused the Singleton to be re-initialized, causing
it to create another MemoryManager instance.

Fixes #3226

21d5f4ada1 Kernel: Absorb LibBareMetal back into the kernel 
This was supposed to be the foundation for some kind of pre-kernel
environment, but nobody is working on it right now, so let's move
everything back into the kernel and remove all the confusion.

5cc09b0245 Kernel: Simplify VMWareBackdoor somewhat 
- If there is no VMWare backdoor, don't allocate memory for it.
- Remove the "unsupported" state, instead just don't instantiate.
- Move the command-line parsing from init to the driver.
- Move mouse packet reception from PS2MouseDevice to VMWareBackdoor.

0fc60e41dd Kernel: Use klog() instead of kprintf() 
Also, duplicate data in dbg() and klog() calls were removed.
In addition, leakage of virtual address to kernel log is prevented.
This is done by replacing kprintf() calls to dbg() calls with the
leaked data instead.
Also, other kprintf() calls were replaced with klog().
