Kernel: Make File::write() and File::read() return KResultOr<size_t>
...
Instead of returning a ssize_t where negative values mean error,
we now return KResultOr<size_t> and use the error state to report
errors exclusively.

Kernel: Use a FlatPtr for the "argument" to ioctl()
...
Since it's often used to pass pointers, it should really be a FlatPtr.

Meta: Add license header to source files
...
As suggested by Joshua, this commit adds the 2-clause BSD license as a
comment block to the top of every source file.
For the first pass, I've just added myself for simplicity. I encourage
everyone to add themselves as copyright holders of any file they've
added or modified in some significant way. If I've added myself in
error somewhere, feel free to replace it with the appropriate copyright
holder instead.
Going forward, all new source files should include a license header.

Kernel: Make File's can_read/can_write take a const FileDescription&
...
Asking a File if we could possibly read or write it will never mutate
the asking FileDescription&, so it should be const.

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: 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.
