2830a0ecda Kernel: Move ProcFS related overrides in Process to ProcessProcFSTraits 
This allows us to 1) let go of the Process when an inode is ref'ing for
ProcFSExposedComponent related reasons, and 2) change our ref/unref
implementation.

748938ea59 Kernel: Handle allocation failure in ProcFS and friends 
There were many places in which allocation failure was noticed but
ignored.

51b6bd8d95 Kernel/USB: Remove UAF in device removal 
I was using a raw pointer instead of a RefPtr to keep the device alive
during removal.

872c75ac44 Kernel/USB: Split SysFS code into its own file 
This makes it controller agnostic and allows us to access it from the
USB hub code.

The copyright says "Liav A." because git blame says he wrote this.

b6a2bbba3b Kernel/USB: Replace PortNumber enum with a raw u8 
A hub can technically have up to 255 ports, given that bNbrPorts is a
u8 and the DeviceRemovable field is a VLA to support up to 255 ports.

Source: USB 2.0 Specification Section 11.23.2.1

That means this enum is not going to scale well in terms of size.
Replacing it with a raw u8 allows me to remove the two port assumption
and a cast.

86ccacf6b5 Kernel/USB: Remove get_device_{at_port,from_address} 
Nothing was using these. These can be put back in the future if
required. This also allows removing the devices array in UHCI.

14da080dcf Kernel/USB: Use allocate_kernel_region in Transfer buffer allocations 
Previously it would create a contiguous AVMO manually and pass it to
MM. This uses supervisor pages that quickly run out as they never get
returned and crash the system.

Instead, use allocate_kernel_region as we're only allocating a page so
it will be contiguous and will be returned when destroyed.

A potentially better solution would be to use a pool of transfers to
avoid all the allocations. This just prevents the system from crashing
within ~5 seconds from the continuous hub polling.

740140a661 Kernel+LibC: Share definitions in fcntl.h and sys/types.h 
This patch begins the work of sharing types and macros between Kernel
and LibC instead of duplicating them via the kludge in UnixTypes.h.

The basic idea is that the Kernel vends various POSIX headers via
Kernel/API/POSIX/ and LibC simply #include's them to get the macros.

0847ad9ca0 Kernel/PCI: Assign a PCI address in the SysFS PCI device directories 
This is a bug that went unnoticed for a long time, so the exposed values
in SysFS PCI device directories were incorrect because the assigned PCI
address was simply the host bridge always.

Also, the bus typing should really be two hexadecimal digits and not 4
digits.

7676edfb9b Kernel: Stop allowing implicit conversion from KResult to int 
This patch removes KResult::operator int() and deals with the fallout.
This forces a lot of code to be more explicit in its handling of errors,
greatly improving readability.

an Inode or not an Inode.

e06660d33c Kernel/ProcFS: Get unveil stats instead of FDs stats for unveil data

`procfs_get_unveil_stats`.

85ea66932e Kernel: Allow kfree_aligned to be called on null pointers 
The C++ standard specifies that `free` and `operator delete` should
be callable with nullptr. The non-aligned `kfree` already handles this,
but because of the pointer arithmetic to obtain the allocation start
pointer, the aligned version would produce undefined behavior.
