94ca55cefd 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.

5de483cfbb Kernel: Move DiskDevice::block_size() up to BlockDevice
All block devices should have a block size, after all. This defaults to
PAGE_SIZE if no size is specified.

401c87a0cc Kernel: mount system call (#396)
It is now possible to mount ext2 `DiskDevice` devices under Serenity on
any folder in the root filesystem. Currently any user can do this with
any permissions. There's a fair amount of assumptions made here too,
that might not be too good, but can be worked on in the future. This is
a good start to allow more dynamic operation under the OS itself.

It is also currently impossible to unmount and such, and devices will
fail to mount in Linux as the FS 'needs to be cleaned'. I'll work on
getting `umount` done ASAP to rectify this (as well as working on less
assumption-making in the mount syscall. We don't want to just be able
to mount DiskDevices!). This could probably be fixed with some `-t`
flag or something similar.

27f699ef0c AK: Rename the common integer typedefs to make it obvious what they are.

* u8, u16, u32, u64 (unsigned)
* i8, i16, i32, i64 (signed)

ebf645d72a Kernel: Tidy up IDEDiskDevice a bit.
The main cleanup here is putting the I/O address base in a member variable.

c7d8aa6969 IDEDiskDevice: Support reading multiple sectors at a time with DMA.
This is another sizable improvement to GCC compile times.
