Kernel: Display virtual addresses as V%p instead of L%x
...
The L was a leftover from when these were called linear addresses.

Kernel: Implement generic framebuffer ioctls in BXVGA
...
This also hides some functions that were previously public, since that
same functionality is now exposed via ioctl functions.

Kernel: Use established device name and number for framebuffer
...
This is to prepare for other framebuffer implementations, for which it
would be inappropriate to use the /dev/bxvga device name.

Kernel: Split VMObject into two classes: Anonymous- and InodeVMObject
...
InodeVMObject is a VMObject with an underlying Inode in the filesystem.
AnonymousVMObject has no Inode.
I'm happy that InodeVMObject::inode() can now return Inode& instead of
VMObject::inode() return Inode*. :^)

Kernel: Remove unnecessary use of LibDraw.
...
BXVGADevice was using a Size object for its framebuffer size. We shouldn't
be pulling in userspace code in the kernel like this, even if it's just
headers. :^)

AK: Rename the common integer typedefs to make it obvious what they are.
...
These types can be picked up by including <AK/Types.h>:
* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

Kernel: Rename FileDescriptor to FileDescription.
...
After reading a bunch of POSIX specs, I've learned that a file descriptor
is the number that refers to a file description, not the description itself.
So this patch renames FileDescriptor to FileDescription, and Process now has
FileDescription* file_description(int fd).

Kernel: Memory-mapped files now have the absolute path as their name.
...
It's generated when the mapping is first created, so it won't update if
the file moves. Maybe that's something we should support, too.

Kernel: Make the Process allocate_region* API's understand "int prot".
...
Instead of having to inspect 'prot' at every call site, make the Process
API's take care of that so we can just pass it through.

Kernel: Pass 'prot' argument to File::mmap() and act on it.
...
Nothing crazy, this just means that PROT_READ allocates readable regions,
and that PROT_WRITE allocates writable ones.

Kernel: Have File virtuals take a FileDescriptor& rather than a Process&.
...
This will allow us to implement different behaviors depending on the role
of the descriptor a File is being accessed through.
