b91c49364d AK: Rename adopt() to adopt_ref() 
This makes it more symmetrical with adopt_own() (which is used to
create a NonnullOwnPtr from the result of a naked new.)

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.

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
    find . \( -path ./Toolchain -prune -o -path ./Build -prune -o -path ./Kernel -prune \) -o \( -name '*.cpp' -o -name '*.h' \) -print | sort > $tmp/EverythingExceptKernel.files

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

    comm -23 $tmp/Kernel.macros $tmp/EverythingExceptKernel.macros > $tmp/Kernel.unique
    comm -1 $tmp/Kernel.macros $tmp/EverythingExceptKernel.macros > $tmp/EverythingExceptKernel.unique

    cat $tmp/Kernel.unique | awk '{ print "#cmakedefine01 "$1 }' > $tmp/Kernel.header
    cat $tmp/EverythingExceptKernel.unique | awk '{ print "#cmakedefine01 "$1 }' > $tmp/EverythingExceptKernel.header

    for macro in $(cat $tmp/Kernel.unique)
    do
        cat $tmp/Kernel.files | xargs grep -l $macro >> $tmp/Kernel.new-includes ||:
    done
    cat $tmp/Kernel.new-includes | sort > $tmp/Kernel.new-includes.sorted

    for macro in $(cat $tmp/EverythingExceptKernel.unique)
    do
        cat $tmp/Kernel.files | xargs grep -l $macro >> $tmp/Kernel.old-includes ||:
    done
    cat $tmp/Kernel.old-includes | sort > $tmp/Kernel.old-includes.sorted

    comm -23 $tmp/Kernel.new-includes.sorted $tmp/Kernel.old-includes.sorted > $tmp/Kernel.includes.new
    comm -13 $tmp/Kernel.new-includes.sorted $tmp/Kernel.old-includes.sorted > $tmp/Kernel.includes.old
    comm -12 $tmp/Kernel.new-includes.sorted $tmp/Kernel.old-includes.sorted > $tmp/Kernel.includes.mixed

    for file in $(cat $tmp/Kernel.includes.new)
    do
        sed -i -E 's/#include <AK\/Debug\.h>/#include <Kernel\/Debug\.h>/' $file

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 }' {} \;

f64e287b82 Kernel: Make device generate their own names 
Besides removing the monolithic DevFSDeviceInode::determine_name()
method, being able to determine a device's name inside the /dev
hierarchy outside of DevFS has its uses.

9dc8bea3e7 Kernel: Allow to boot from a partition with partition UUID 
Instead of specifying the boot argument to be root=/dev/hdXY, now
one can write root=PARTUUID= with the right UUID, and if the partition
is found, the kernel will boot from it.

This feature is mainly used with GUID partitions, and is considered to
be the most reliable way for the kernel to identify partitions.

72b1998f0d Kernel: Introduce a new partitioning subsystem 
The partitioning code was very outdated, and required a full refactor.
The new subsystem removes duplicated code and uses more AK containers.

The most important change is that all implementations of the
PartitionTable class conform to one interface, which made it possible
to remove unnecessary code in the EBRPartitionTable class.

Finding partitions is now done in the StorageManagement singleton,
instead of doing so in init.cpp.

Also, now we don't try to find partitions on demand - the kernel will
try to detect if a StorageDevice is partitioned, and if so, will check
what is the partition table, which could be MBR, GUID or EBR.
Then, it will create DiskPartitionMetadata object for each partition
that is available in the partition table. This object will be used
by the partition enumeration code to create a DiskPartition with the
correct minor number.
