2cee2a85e6 Kernel: DevFS now stores all devices 
This allows removing hack in PCI that was required to keep NVMe
controller alive.

fdb6dc94ba Kernel: cast between inheritance with static_cast 
using reinterpret_cast is not a good idea. preferably we would use
dynamic_cast, but that is not possible since kernel is compiled with
-fno-rtti.

fd18071975 Kernel: Implement TerminalDriver for Framebuffer device 
Use this new FramebufferTerminalDriver for terminal instead of the
old VesaTerminalDriver. Only drawback with this is that framebuffer
device can only be intialized after DevFS is initialized.

2301654c4e Kernel: Rework RamInode API 
RamInode is now a general RamInode with no data. RamFileInode is now
a inode for regular files. This is much cleaner and more intuitive
since there is no reason for most non-regular inodes to hold data
Vector.

1e6930a3bc Kernel: SYS_SYNC now schedules sync to happen soon 
You can pass non-zero argument to the syscall to block until the
sync has finished.

63dc2b6aa6 Kernel: Implement SYS_SYNC and add sync executable to userspace 
You can (and have to) manually sync disk after writes to it.

323de3c866 Kernel: Rework whole Terminal structure 
Serial monitors can now be used as a output. This requires editing
init code for the stdio opening. Serial input is not supported, so qemu
still needs graphical window for ps/2 keyboard.

c732297623 Kernel: Rename TimerHandler to SystemTimer 
I changed SystemTimer to only handle the "best" supported timer
it can initialize.

9bcfb34524 Kernel: Rewrite whole device structure 
We now have DevFileSystem which is derived from RamFileSystem. All
devices are RamInodes. We don't have separate DeviceManager anymore.
To iterate over devices, you can loop througn every inode in devfs.
