Kernel: Check whether ELF address space can be loaded
...
Before reserving address space in SYS_EXEC verify that ELF address
space is actually loadable. For example when trying to execute the
kernel binary in userspace, binarys address space would overlap with
current kernel address space. Now kernel won't crash anymore and
will just send SIGKILL to the process calling exec*().

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.

Kernel: fix some math in physical ranges
...
I allocated 1 bitmap page per 8 data pages. Bitmap page can actually
store 8*PAGE_SIZE data pages.
Also properly set last bits in bitmap. I did not care about endianness
but now we set the bits on unsigned long longs instead of bytes.
