LibELF: Optimize LoadableELF::clone() memory usage
...
We only clone mapped pages that have been marked as writeble.
Read/execute only pages will be exactly as in the file itself and
can be demand paged also :D

LibELF: Implement new ELF structure
...
This structure is used for demand pagable execution. It handles all
memory allocation and file reading.

BuildSystem: use -a with rsync
...
This allows cmake to not rebuild whole project every time

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.

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/LibC: move file offset back to kernel

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 :)
