shamelessly stolen from newlib

yeah, I guess it was just a coincidence that the segment was aligned.

turns out that I need to do what I thought in the first place.

Heap

See merge request bslathi19/summeros!1

In userspace lib, there is a static array called lookup,
but the code is looking on the wrong place (4kb off)

pointer arithmatic got me again, I need to add 512*16 bits
since buf is a 16 bit type.

THIS DOES NOT WORK
the parent program image is gone somehow

bad inode value is -1, not 0

can't halt yet, but that's fine.

previously all blocks were were stored in memory at the same place

finally get rid of the defined but not used warning.

turns out that last commit still used a constant lol

before this it used a constant, which might not always be the case.
