Commit: Tidy up readelf's use of boolean values

[Nick Clifton <nickc at redhat dot com>]

Hi Guys,

  I have been meaning to tidy up readelf's use of boolean values for a
  long time now, and I finally gotten the time to do so.  The attached
  patch basically does two things:

   * Replaces an "int" type with "bfd_boolean" when the variable
     is being used as a boolean value.

   * Inverts the logic of some of the higher level functions so
     that now all boolean functions return TRUE upon success and
     FALSE upon failure.

  Tested, with no regressions, on lots of different targets.

Cheers
  Nick
