Bananymous 80e7a89f67 BuildSystem: Base sysroot is now distributed as a tar ball 
This allows file and directory permissions work as intended.

cmake is now filled with 'sudo' but with sudo timeout this should be
fine.

Bananymous 275a730485 LibELF: We use BAN::Vector<uint8_t> as elf storage 
This is made possible by the dynamic kmalloc

Bananymous 801025ad7b 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.

Bananymous 80d9f6131b Kernel/LibC: move file offset back to kernel

Bananymous ff2e2937a5 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 :)
