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.

Add clang-format file
...
Also run it across the whole tree to get everything using the One True Style.
We don't yet run this in an automated fashion as it's a little slow, but
there is a snippet to do so in makeall.sh.

IDEDiskDevice: Implement basic DMA writes.
...
This could share more code with reads, and generally be better. But it works
and it's considerably faster than PIO, so let's use it. :^)

Kernel: Tidy up IDEDiskDevice a bit.
...
The main cleanup here is putting the I/O address base in a member variable.

IDEDiskDevice: Add support for DMA reads.
...
I've only tested this with the PIIX3 chipset QEMU emulates, but it works
pretty well here. GCC compile times are cut roughly in half :^)

Kernel: Add a beep() syscall that beeps the PC speaker.
...
Hook this up in Terminal so that the '\a' character generates a beep.
Finally emit an '\a' character in the shell line editing code when
backspacing at the start of the line.

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.

I never realized the right shift key wasn't hooked up since my left pinky
always hovers over the left shift key, ready to rock.

There are much faster ways to do disk transfers, but I'm not implementing
those today. In the meantime, this is slightly nicer. :^)

This is then used to implement the userspace dbgprintf() in a far more
efficient way than what we had before. :^)
