0eb6cad1ba Detect end-of-unwind 
According to LibUnwind:src/x86_64/Gstep.c:85
(HEAD=c91974f30feac05055621e33ca101a371236c786), the x86_64 ABI states
that the end of the call stack is determined by either a null RBP or an
undefined return-address column in the DWARF.

c4895ed0d1 Make context acquisition behave correctly wrt. calling site 
It now actually returns the context at the call site of the function,
instead of somewhere inside DwarfInterpret

97032ee31b Actually able to unwind the stack 
This is filled with debug prints, and is quite brutal: it saves the
whole stack. It has to be optimized a lot.

Also, needs a smooth stop when trying to unwind main.
