c4437e19bd LibDebug+Everywhere: Make DebugInfo not own the ELF image
This is required to avoid copying the image where otherwise a reference
would be enough.

57417a3d6e Kernel: Support loading the kernel at almost arbitrary virtual addresses
This enables further work on implementing KASLR by adding relocation
support to the pre-kernel and updating the kernel to be less dependent
on specific virtual memory layouts.

60d6137e73 Userland: Use /proc/kernel_base to determine the kernel base address
This removes all the hard-coded kernel base addresses from userspace
tools.

One downside for this is that e.g. Profiler no longer uses a different
color for kernel symbols when run as a non-root user.

This speeds up the boot process considerably when specifying the kernel
image via -initrd.

25c73159ce LibCoreDump: Don't subtract one from the first stack frame's EIP
The first stack frame represents the current instruction pointer
rather than the return address so we shouldn't subtract one
from it.

Fixes #8162.

e9e4358a93 LibDebug: Store LibDebug objects on the heap & make them non-copyable
This fixes an issue were some LibDebug objects (for example,
Dwarf::CompilationUnit) held a reference to their parent
Dwarf::DwarfInfo object, which was constructed on the stack and later
moved to the heap.
