12c7b954e1 Kernel+WindowServer: Move setting tty graphical mode to Userspace
This will allow using the console tty and WindowServer regardless of
your kernel command line. Also this fixes a bug where, when booting in
text mode, the console was in graphical mode, and would not accept
input.

5ed3f7c6bf Kernel/Storage: Migrate the partition code to use the ErrorOr container
That code used the old AK::Result container, which leads to overly
complicated initialization flow when trying to figure out the correct
partition table type. Instead, when using the ErrorOr container the code
is much simpler and more understandable.

19912a0b32 Kernel+Utilities: Add the route utility
This exposes the global routing table in the /proc directory and adds
the userspace utility to query dynamically add from the table.

8596b1e0c3 Kernel: Add a global routing table
Previously the system had no concept of assigning different routes for
different destination addresses as the default gateway IP address was
directly assigned to a network adapter. This default gateway was
statically assigned and any update  would remove the previously existing
route.

This patch is a beginning step towards implementing #180. It implements
a simple global routing table that is referenced during the routing
process. With this implementation it is now possible for a user or
service (i.e. DHCP) to dynamically add routes to the table.

The routing table will select the most specific route when possible. It
will select any direct match between the destination and routing entry
addresses. If the destination address overlaps between multiple entries,
the Kernel will use the longest prefix match, or the longest number of
matching bits between the destination address and the routing address.
In the event that there is no entries found for a specific destination
address, this implementation supports entries for a default route to be
set for any specified interface.

This is a small first step towards enhancing the system's routing
capabilities. Future enhancements would include referencing a
configuration file at boot to load pre-defined static routes.

cd3e337487 Kernel: Strip null terminators from all CPUID strings, not just brand
I've noticed that the KVM hypervisor vendor ID string contained null
terminators in the serialized JSON string in /proc/cpuinfo - let's avoid
that, and err on the side of caution and strip them from all strings
built from CPUID register values. They may not be fixed width after all.

300dcb6f5e Kernel/USB: Get all interface descriptors on enumeration

a1df8a1896 Kernel/USB: Add control_transfer() function USB::Device

b0a2572577 Kernel: Don't require AnonymousFiles to be mmap'd completely
AnonymousFile always allocates in multiples of a page size when created
with anon_create. This is especially an issue if we use AnonymousFile
shared memory to store a shared data structure that isn't exactly a
multiple of a page in size. Therefore, we can just allow mmaps of
AnonymousFile to map only an initial part of the shared memory.

This makes SharedSingleProducerCircularQueue work when it's introduced
later.

1462211ccf Kernel: Allow WorkQueue items allocation failures propagation
In most cases it's safe to abort the requested operation and go forward,
however, in some places it's not clear yet how to handle these failures,
therefore, we use the MUST() wrapper to force a kernel panic for now.

063ea0088e Kernel: Enable PS2 keyboard scan code translation if not already enabled
On the QEMU microvm machine type, it became apparent that the BIOS was
not setting the i8042 controller to function as expected. To ensure that
the controller is always outputting correct scan codes, set it to scan
code 2 and enable first port translation to ensure all scan codes are
translated to scan code set 1. This is the expected behavior when using
SeaBIOS, but on qboot (the BIOS for the QEMU microvm machine type), the
firmware doesn't take care of this so we need to do this ourselves.

a1686db2de Kernel: Skip setting region name if none is given to mmap
This keeps us from accidentally overwriting an already set region name,
for example when we are mapping a file (as, in this case, the file name
is already stored in the region).

2f4ab64e8c Kernel: Use kernel_mapping_base as the minimum kernel stack address
Since KASLR was added kernel_load_base only signifies the address at
which the kernel image start, not the start of kernel memory, meaning
that a valid kernel stack can be allocated before it in memory.

We use kernel_mapping_base, the lowest address covered by the kernel
page directory, as the minimal address when performing safety checks
during backtrace generation.
