Add output_type to bfd_link_info

The "shared" field in bfd_link_info is set for both DSO and and PIE.
There are separate fields for executable and relocatable outputs.  This
patch adds an "output_type" field:

enum output_type
{
  type_unknown = 0,
  type_executable,
  type_dll,
  type_relocatable
};

and a "pic" field to bfd_link_info to replace shared, executable and
relocatable fields so that we can use the "output_type" field to check
for output type and the "pic" field check if output is PIC.  Macros,
bfd_link_executable, bfd_link_dll, bfd_link_relocatable, bfd_link_pic
and bfd_link_pie, are provided to check for output features.
