Add DDB_NUMSYM option which in addition to the symbolic representation
also prints the actual numerical value of the symbol in question.
Users of addr2line(1) will be less proficient in hex arithmetic as a
consequence.
This amongst other things means that traceback lines change from:
siointr1(c4016800,c073bda0,0,c06b699c,69f) at siointr1+0xc5
to
siointr1(c4016800,c073bda0,0,c06b699c,69f) at 0xc062b0bd = siointr1+0xc5
I made this an option to avoid bikesheds.
