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.
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 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.
Process-separated symbolication was cute, but ultimately the threat
model is kinda silly. We're already *running* the binary, but we're
afraid to parse its symbol table? :^)
This commit makes SystemMonitor and bt do symbolication in-process.
SymbolServer and the symbol user will be removed separately.
