  Log:
  Fix sign-extension bug for 32 and 64-bit values. For 64-bit values
  this involves the sign-extension of the high and low "word". Both
  of which are 32-bit. The bug is especially harmful on ia64, where
  0x9fffffffe0000000 is a common address (base of register stack).
  This was invariably displayed as 0xffffffffe0000000.
  
  The sign-extension is fixed by using {b|l}e{16|32|64}dec() where
  applicable. Since elfdump(1) is not a bootstrap tool, dependency
  on these functions is not a problem.
