Proposed patch

Hi Pali,

  OK, here is an initial patch to add support for the various IMAGE_SCN_...
  flags to objcopy's --set-section-flags option.  The patch is not complete
  yet - it does not update the documentation or the testsuite - but I thought
  that you might like to give it a try.

  One problem that I have found is that the BFD library enforces certain
  flags for certain sections (when working with PE format files).  So for
  example the .text section is always given IMAGE_SCN_MEM_READ, 
  IMAGE_SCN_CNT_CODE and IMAGE_SCN_MEM_EXECUTE, and this cannot be changed
  via the --set-section-flags option.  I am not 100% sure, but I think that
  this behaviour may actually be mandated by the PE file format specification.

Cheers
  Nick
