Kernel: Big commit. Rewrite ELF loading code
...
We now load ELF files to VirtualRanges instead of using kmalloc.
We have only a fixed 1 MiB kmalloc for big allocations and this
allows loading files even when they don't fit in there.
This caused me to rewrite the whole ELF loading process since the
loaded ELF is not in memory mapped by every process.
Virtual ranges allow you to zero out the memory and to copy into
them from arbitary byte buffers.

Kernel: Remove offset from OpenFileDescriptor
...
This is now handled on the libc side. There might be reasons to
have it in kernel side, but for simplicity's sake I'm moving it
to libc for now :)
