Bananymous adc5ff9e99 Kernel: Implement AHCI driver
SATA drives can now be used with banan-os. This allows much faster
disk access (writing 10 MiB from 30s to 1.5s). This can definitely
be optimized but the main slow down is probably the whole disk
structure in the os.

AHCI drive is now the default when running qemu.

Bananymous 8621d8a155 BuildSystem: Rework calling qemu
I change always manually the serial/graphical. When running cmake
you can define variable QEMU_ACCEL that will be used as accelerator.

Also ninja has the following targets for running qemu
  1. qemu:            Run graphical qemu environment
  2. qemu-nographic:  Run qemu without graphical screen. You should
                      select 'serial only' from grub menu.
  3. qemu-debug:      Run qemu without accelerator and interrupt
                      debugger.

Bananymous 4c5176f751 BuildSystem: We are now using cmake instead of plain make
I have been annoyed for a while since I had to build everything
when running the os since the buildsystem was really bad.

I wanted to rewrite the whole build system and changed to using cmake

:)

Bananymous 0eb1fb8bae Buildsystem: Build disk image manually
We don't use grub-mkrescue anymore. Instead we build the disk image
manually. This allows us to have known disk layout for easier testing
when I get to implementing disk reading. For now I made the root
partition ext2 since I think that will be the first format that I'll
implement.

Bananymous 0bdb01ee04 Kernel: Replace PIC with APIC
If APIC/IOAPIC is not found, we fallback to PIC

Interrupts don't seem to work on real hardware (?)

Bananymous 3d3f12bd30 Kernel: Add new generic Printer class
kprint is now just a #define to Printer::print<terminal_putc>.

This allows us to use same print formatting for serial output :)
