x86: add the capability to print fuzzy backtraces
For enhancing the 32 bit EBP based backtracer, I need the capability for the backtracer to tell it's customer that an entry is either reliable or unreliable, and the backtrace printing code then needs to print the unreliable ones slightly different. This patch adds the basic capability, the next patch will add a user of this capability.
