RFC: Objdump: Dumping PE specific headers

[Nick Clifton]

Hi Guys,

  Whilst looking at PR 310145, I realised that we currently do not have
  a way to display the contents of PE type files in their native
  format.  Since objdump does have a --private option which provides
  this kind of functionality for other file format types, I thought that
  it would be helpful if objdump could also handle PE files.  Hence this
  patch.

  At the moment it only dumps the file header and section headers, but
  this could be extended in the future.  (Especially if someone else is
  interested in doing the work...).  The output looks something like
  this:

    $ objdump -P header,sections test-section-flags.exe --wide

    test-section-flags.exe:     file format pei-x86-64

    PEI File Header:
      Magic:         0x5a4d		- IMAGE_DOS_SIGNATURE
      Machine Num:   0x8664		- AMD64
      Num sections:  6
      Time and date: 0x646f522d		- Thu May 25 13:18:53 2023
      Symbols off:   0x00001000
      Num symbols:   60
      Opt hdr sz:    240
      flags:         0x0226		- EXECUTABLE,LINE NUMS STRIPPED,LARGE ADDRESS AWARE,DEBUG STRIPPED

    Section headers (at 152+240=0x00000188 to 0x00000278):

  Thoughts, comments ?
