  Issue #7355: Various improvements to struct module documentation.

   - note early on that the result of struct.pack includes padding
     bytes by default

   - add examples showing how order of struct fields can affect size
     (due to padding)

   - better headers and references; introduction to format strings

   - integrate packing notes into table

  Many thanks to Meador Inge for the patch.
