PATCH: Update DWARF3 decoding ability

[Nick Clifton]

Hi Guys,

   I am applying the attached patch to update readelf's (and objdump's) ability 
to display DWARF3 debug information.  It adds support for some of the new 
values defined in the DWARF3 spec.  I also updated the dwarf2.h header to 
mention where the DWARF3 spec can be found on the web, and to put the in proper 
names for a couple of deprecated strings.

Cheers
   Nick
