Kernel: Clear AHCI pending interrupts

constatly spamming interrupts like crazy :D

Kernel: Disable USB Mass Storage writing until I get it fixed
...
This prevented real hw from running for over 10-20 seconds. When first
disk sync happens after 10 secods, USB storage would enter faulty state
and not allow any io operations.
I have no idea what the problem is. If I don't send Reset command to the
USB device writing seems to work fine. I also don't think its part of
the Reset process either as reading works just fine.

Kernel: Fix Thread destruction after sys_exit
...
This had undefined behaviour as Thread's (Processes's) PageTable was
destroyed before Thread had the change to destroy its own stacks that
lived on the PageTable.

If root device is initialized asynchronously it may not be ready when

Kernel: Check max packet size for all USB devices

Spec says that this has to be done. Most cases can be probably skipped

USB device now sets its own data buffers for IN/OUT endpoints. This

c07fd265f0
Kernel: Add support for ATA CHS addressing and cleanup code
...
I thought that I had an PC without LBA support so I implement support
for CHS. Turns out that my ATA device detection was broken and was no
device on that port and initialize data was just garbage.
Now that I added CHS, I guess I should just keep it in :)
Both ATA read and write are now combined into a single function to avoid
code duplication.

Kernel/init: /dev/tty is now custom symlink to controlling terminal
...
kernel now passes the name of default console to init process so init
knows which file to open as stdio. before /dev/tty was referencing the
system wide current terminal which was inherited from cmdline. This
doesn't work anymore as we have pseudo terminals implemented that can
chage the current terminal during runtime :D

Quake II needs a lot of stack, it was overflowing my 256 KiB stack so
this patch doubles that, so Quake II can run!
Also every thread had 256 KiB kernel stack. This is unnecessarily large
and now dropped to 32 KiB.
