[RFA] Add missing gdb_bfd.h includes

["Pierre Muller" <pierre dot muller at ics-cnrs dot unistra dot fr>]

  It seems that "gdb_bfd.h" header is not included in several
c files.
  I noticed that with a compilation failure for native windows:
gcc -g -O2    -I. -I../../puresrc/gdb -I../../puresrc/gdb/common
-I../../puresrc/gdb/config  -DLOCALEDIR="\"/usr/local/s

Makefile:962: recipe for target `windows-nat.o' failed

Upon investigation I found several missing gdb_bfd.h header,
mainly in native files.

This patch adds the header to any C source that had a match for
grep  gdb_bfd *.c
but no corresponding header inclusion.

   All those file seem to call at least gdb_bfd_unref function,
so I suppose that the inclusion is correct, but 
I would still prefer an approval from Tom, 
as he seemed to have committed all the gdb_bfd header related changes.
  
Is this OK?

As usual, 
 1) I am not  sure about correct wording for ChangeLog
 2) I never really understood the ordering logic (or to
be more precise, if there is an ordering logic) of C headers
in C source files, thus I inserted them more or less randomly...
 
 Tom, if you feel like putting them on the right place,
don't hesitate to commit yourself...
