lddiff tool to diff ldd of two or more files

Lddiff lists shared libs required by programs or libs. For two or more files it aligns them as a line-by-line diff. It's a wrapper of ldd and od.

      red  missing libs
  default  primary libs, referenced directly from the file
    green  libs referenced from libs
  magenta  additional libs not seen by `ldd` but found by `od`
    black  blacked-out libs present in all existing columns  
    white  blacked-out libs with columns missing, `-dw` option
